The cleaning c~ disclosed herein are effective at cleaning wheel surfaces formed of painted steel, painted aluminum, chrome, stainless steel, clear coatedaluminum, or plastic, without etching or pitting these surfaces. The cleaning ' contain a fluoride salt or cn~nhin~tirm of fluoride salts. The fluoride salt-10 containing cleaning ~ Al;o~,c of the prior art typically function by etching the surface to be cleaned, and thus are unsuitable for use on wheel surfaces.
The active ingredients in the cleaning ~ are acid fluoride salts and detergents or organic solvents. As used herein, the terrn "acid fluoride salt" refers to a partially neutralized salt of hydrogen nuoride and other fluoride salts which when 15 dissolved in water have a pH o~ less than 7. The acid fluoride salts effectively dissolve inorganic soils such as brake dust, while the detergents and/or organic solvents dissolve and emulsify tlle oranic soils. Accordingly, as used herein, the oerm "organic soil removing agent" rerers to detergents and/or organic solvents that are capable of dissolving and ~ ;r~,;l.g organic soils.
20 Suitable acid fluoride salts include metal ~luorides, such as alkali metal fluorides, and ~lnm~-ni~lm fluorides. Specific acid fluoride salts are potassium bifluoride, sodium bifluoride,: fluorides, calcium lluu~ , An~n~ ' bifluoride, sodiunl nuorosilicates, and the like. They are effective in removing inorganic soils fi-om wheel surfaces without e~ching the surface when used in amounts of about I to 25 about 20 percent by weight. Preferably they are used in amounts of about 5 to about 15 percent by weight. r.-"""~ containing greater than 20 percent by weight can be prepared, however cost becomes a factor, unless the cleaning solution is prepared as a ~,o--u~ which is to b~ diluted prior to use. Crystallization and solubility of tl~e acid fluoride salts and other incredients can also be a problem in some 30 fi~rm~ tionc when reater than 20 percent by weight of the salt is used. The pH of 2 ~ 77278 wo 9S/16006 Pcrluss4ll3s tlle f..".., ~ c is preferably between 3.0 to about 6.5. At pH below 3.0 hazing and etching of the surface which is cleaned can occur, thus damaging the wheel. Above pH 6.5 cleaning effectiveness declines.
Suitable detergents are any detergents capable of dissolving and e..-ul~ir~;..& organic 5 soils. Such detergents include, but are not limited to, the anionic synthetic detergents such as alkyl sulfates such as sodium lauryl sulfate, alkyl ether sulfates, and linear alkyl benzene sulfonates. Additionally, various nonionic surfactants can be used in the cleaning ~ .. For example, suitable nonionic surfactants include coconut , amine oxides, nonyl phenol ethoxylate, ~LIIu7~yl~L~d alcohols, 10 ethoxylate ~llUpU~ ' ' block co-polymers, and the like.

The amount of detergent used in the ~ is not critical so long as it remains 15 soluble in an aqueous solution at pH of about 3.0 to 6.5 and is capable of dissolving and emulsifying organic soils. The amount of detergent used typically depends on the t!~pe used. For example, nonionic detergents, such as amine oxides, are typically used ill amounts of about 0.5 to about 32.5 weight percent. Anionic synthetic detergents are t~pically used in amounts of about 0.10 - 25 weight percent depending on the desired 20 Icvel of foaming.

-6-t~rpenes include limonene, dipentene, ~erpinene, and olher monocyclic and bicyclic tcrpenes. Terpenes are typically used in amounts of less than about 8 weight percenl.
Cleaning ~ i..,,c containing the acid fluoride salt and detergent or organic solvent in the f~ ;.- c described herein can be used to effectively clean the 5 surfaces of most wheels, including painted steel, painted aluminum, chrome, stainless sleel, clear coated aluminum, and plastic. However, for cleaning untreated aluminum surfaces it is necessary to prevent hazing of the aluminum. Hazing is the d~ .l of a hydrated aluminum oxide layer on the surface of the wheel. Certain ~ml ~ ' of the present invention are effective at cleaning uncoated aluminum without causing 10 hazing. It has been found that the ratio of anion to acid is an important variable to consider in the rl-..1~ ,,. of a cleaning solution that is to be used on untreated aluminum. This ratio is a mole ratio wherein the nunlber of moles of anions is divided by the number of moles of the acid. For example. H2SO~ has a ratio of (I)SOJ2Ht,or 0.5. H3POJ has a ratio of (I)PO~/3Ht = 0.33. The present invention provides 15 cleaning rv. ,..,.l_li,...~ tllat safely clean untreated aluminum with reduced hazing to no hazing wherein the molar ratio of anion to acid is about 3.5 or more. Preferably the molar ratio of anion to acid is about 4.0 or more. The anion to acid ratio of the present r~.. "l-,;.. ~ can be increased into the desired range suitable for cleaning untreated aluminum by the addition of soluble salts. Suitable salts are any salt that is 20 svluble enough to provide the desired amount of anions. Ammonium acid fluoride and acetate are examples of salts which have sufficient solubility to provide anion to acid ratios in the f -, ,.~ of the present invention of greater than 4Ø
The cleaning composition can contain other types of cleaning agents in addition to the 25 fluoride acid salts and detergents or solvents. For example a scouring agent such as sodium m~ cili~ can be illCU~ into the formulation if used in amounts that enhance cleaning without pitting the surfaces cleaned. Typically, scouring agents are used in amounts up to about 2 weight percent. At levels much greater than this, the silicate tends to interfere with the effectiveness of the cleaner unless the fluoride 30 source is a lluv-~ ' .based material.
Wo 95/16006 PCTIUS94/13961 Additionally, non-aclive agcnts can b~ added to enhance various properties of the cleaning .UIllpOsi~iu~l. For example, thickening agents, such as polyacrylic acids, clay, xanthan gums, alginates, other natural gums, and the like, may be added. The purpose of these materials is to enhance the viscosity and thereby provide better cling of the 5 cleaning ~ .,. Cling, anti-sag, or viscosity allows the cleaning ~ to - stay in better contact with vertical surfaces, thereby enhancing its ~r~Li~ .css.
Various emulsifiers and dispersing agents can be used such as the pol~l-oD~Jh~,tt, builders sodium L ilJolyyhuD~ t., and ~ .-, ' . ' as well as sodium citrate and other emulsifiers cûmmonly used in the art. These are typically used at 10 Icvels of about O.l to about 5 weight percent and may also include acid phosphates such as mono and disodium phosphate and sodium acid l~y~ul ' il ' Propellants may also be used so that the cleaning cnmrnCi~inn can be applied as an a~rosol. Suitable propellants include ~Ulll~ DD~;d air, nitrogen, and the usu~1 hydrocarbon and chlorinated nuulu~ O~I propellants.
15 Typically these formulas are made by first dissolving the acid tluoride salts since these tcnd to be C,lduLll~"lllic and need time to go into solution. The surfactants are then added followed by the solvents. When insoluble solvents are used such as d-limonene, dipentene, and the like, the solvent is first blended into the surl`actants then the water is added and mixed until uniform. The acid fluoride salt is then added either in a flake 20 f~rmllla~inn or as a solution with enough water to solubiliæ the fluoride salt.
Il other materials such as silicates or phosphates are used. they are îypically dissolved il~ the water followed by tlle detergents and surfactants with the acid fluoride salt being added last either as the flake or as a solution. When a solution is used, just enough ~ater is added to the llake to dissolve it.
25 Il is important to prepare and store these formulas in plastic of the high density polyethylene, ~olypropylene, or poly\,;.,yl.l,lo.id~ types. The ~ )os;l;n~ can be mixed in stainless steel but the residencc time should be kept short as there is a t~ndency to attack the grain boundaries. Contact with glass should be avoided because 2 ~ 77278 Wo 9S/16006 PCT/U'594/13961 it ean be etched by the ~ The reacuon wiLh olass can deplete Lhe c~ ,r~ ;.... of active fluoride ions.
11l use, the ~ can be dispensed from any of the plastic boltles and sprayers tvpieally used, but care must be taken to avoid using meLal parts in Lhe sprayers as the 5 metal parts can corrode and clog the spraying apparatus, and because the addiLion of standard corrosion inhibitors are not effeetive in the ~ r-~ of the present illvention. Typical aerosol cans cannot be used because the ~ can strip off tlle protective tin plate and organic coatings typically used with such cans. The suecessful use of an aerosol foanl is most easily achieved through the use of 10 technology commonly known in Lhe art as "bag-in-a-can". This employs a laminated plastic bag welded to a valve assembly and the assembly inserted into a normal aerosol can. The cleaning ~ - is filled into the laminated plastic bao. The can is then ,f~:~Ulif~d using any of the normal gases such as ~ air, nitrogen, u~ bù--, or ehlorinated nho~ .,l,u,.~.

Each cleaning ~ o~ - was evaluated and rated for cleaning as described in Example 2 above. The surfaces tesoed were aluminum ~heels having typical road soils and grime on their surfaces. After cleaning, the lS surfaces were evaluated for hazing of the aluminum. A scale of 0 to 5 was used with 0 indicating heavy hazing and 5 indication no hazing. Table 2 outiines the f","-l,l~ evaluated and the results.

As can be seen from Table 2, the cleanin~ formulation of Control #2. which had an anion/Ht ratio of 3.0/1. exhibited rcduced hazing when compared to the Control #1, which had an anion/Ht ratio oî ~.0/1. Examples A-D, which all had ratios greatertllan 4.0, exhibited no hazing yet had excellent cleaning properties.
Cleaning ~ i..,,c containing the acid fluoride salt and detergent or organic solvent in the f~ ;.- c described herein can be used to effectively clean the 5 surfaces of most wheels, including painted steel, painted aluminum, chrome, stainless sleel, clear coated aluminum, and plastic. However, for cleaning untreated aluminum surfaces it is necessary to prevent hazing of the aluminum. Hazing is the d~ .l of a hydrated aluminum oxide layer on the surface of the wheel. Certain ~ml ~ ' of the present invention are effective at cleaning uncoated aluminum without causing 10 hazing. It has been found that the ratio of anion to acid is an important variable to consider in the rl-..1~ ,,. of a cleaning solution that is to be used on untreated aluminum. This ratio is a mole ratio wherein the nunlber of moles of anions is divided by the number of moles of the acid. For example. H2SO~ has a ratio of (I)SOJ2Ht,or 0.5. H3POJ has a ratio of (I)PO~/3Ht = 0.33. The present invention provides 15 cleaning rv. ,..,.l_li,...~ tllat safely clean untreated aluminum with reduced hazing to no hazing wherein the molar ratio of anion to acid is about 3.5 or more. Preferably the molar ratio of anion to acid is about 4.0 or more. The anion to acid ratio of the present r~.. "l-,;.. ~ can be increased into the desired range suitable for cleaning untreated aluminum by the addition of soluble salts. Suitable salts are any salt that is 20 svluble enough to provide the desired amount of anions. Ammonium acid fluoride and acetate are examples of salts which have sufficient solubility to provide anion to acid ratios in the f -, ,.~ of the present invention of greater than 4Ø
The cleaning composition can contain other types of cleaning agents in addition to the 25 fluoride acid salts and detergents or solvents. For example a scouring agent such as sodium m~ cili~ can be illCU~ into the formulation if used in amounts that enhance cleaning without pitting the surfaces cleaned. Typically, scouring agents are used in amounts up to about 2 weight percent. At levels much greater than this, the silicate tends to interfere with the effectiveness of the cleaner unless the fluoride 30 source is a lluv-~ ' .based material.
Wo 95/16006 PCTIUS94/13961 Additionally, non-aclive agcnts can b~ added to enhance various properties of the cleaning .UIllpOsi~iu~l. For example, thickening agents, such as polyacrylic acids, clay, xanthan gums, alginates, other natural gums, and the like, may be added. The purpose of these materials is to enhance the viscosity and thereby provide better cling of the 5 cleaning ~ .,. Cling, anti-sag, or viscosity allows the cleaning ~ to - stay in better contact with vertical surfaces, thereby enhancing its ~r~Li~ .css.
Various emulsifiers and dispersing agents can be used such as the pol~l-oD~Jh~,tt, builders sodium L ilJolyyhuD~ t., and ~ .-, ' . ' as well as sodium citrate and other emulsifiers cûmmonly used in the art. These are typically used at 10 Icvels of about O.l to about 5 weight percent and may also include acid phosphates such as mono and disodium phosphate and sodium acid l~y~ul ' il ' Propellants may also be used so that the cleaning cnmrnCi~inn can be applied as an a~rosol. Suitable propellants include ~Ulll~ DD~;d air, nitrogen, and the usu~1 hydrocarbon and chlorinated nuulu~ O~I propellants.
15 Typically these formulas are made by first dissolving the acid tluoride salts since these tcnd to be C,lduLll~"lllic and need time to go into solution. The surfactants are then added followed by the solvents. When insoluble solvents are used such as d-limonene, dipentene, and the like, the solvent is first blended into the surl`actants then the water is added and mixed until uniform. The acid fluoride salt is then added either in a flake 20 f~rmllla~inn or as a solution with enough water to solubiliæ the fluoride salt.
Il other materials such as silicates or phosphates are used. they are îypically dissolved il~ the water followed by tlle detergents and surfactants with the acid fluoride salt being added last either as the flake or as a solution. When a solution is used, just enough ~ater is added to the llake to dissolve it.
25 Il is important to prepare and store these formulas in plastic of the high density polyethylene, ~olypropylene, or poly\,;.,yl.l,lo.id~ types. The ~ )os;l;n~ can be mixed in stainless steel but the residencc time should be kept short as there is a t~ndency to attack the grain boundaries. Contact with glass should be avoided because 2 ~ 77278 Wo 9S/16006 PCT/U'594/13961 it ean be etched by the ~ The reacuon wiLh olass can deplete Lhe c~ ,r~ ;.... of active fluoride ions.
11l use, the ~ can be dispensed from any of the plastic boltles and sprayers tvpieally used, but care must be taken to avoid using meLal parts in Lhe sprayers as the 5 metal parts can corrode and clog the spraying apparatus, and because the addiLion of standard corrosion inhibitors are not effeetive in the ~ r-~ of the present illvention. Typical aerosol cans cannot be used because the ~ can strip off tlle protective tin plate and organic coatings typically used with such cans. The suecessful use of an aerosol foanl is most easily achieved through the use of 10 technology commonly known in Lhe art as "bag-in-a-can". This employs a laminated plastic bag welded to a valve assembly and the assembly inserted into a normal aerosol can. The cleaning ~ - is filled into the laminated plastic bao. The can is then ,f~:~Ulif~d using any of the normal gases such as ~ air, nitrogen, u~ bù--, or ehlorinated nho~ .,l,u,.~.
