diatomaceous earth and quartz.
4. A metal cleaner-polish comprising a liquid slurry containing at
least 20 percent of finely divided abrasive, at least 30 percent of
aliphatic hydrocarbons, and at least 5 percent isopropanol.
5. The process of cleaning and polishing the exterior surface of
fuel tanks of tractor trailers, comprising dampening a cloth or pad
with a slurry comprising at least 30 percent of finely divided
abrasive, at least 30 percent aliphatic hydrocarbons, and at least
5 percent isopropanol, and wiping the surface with said dampened
cloth or pad.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This is a continuation-in-part of application Ser. No.
09/504,553, filed Feb. 15, 2000.
BACKGROUND OF THE INVENTION
[0003] The cleaner-polish of this invention has particular
application to the fuel tanks of large trucks, but its utility is
not confined thereto. The driver-owners of tractor-trailers (semis)
are meticulous about the appearance of their rigs. They try to get
and maintain a high shine on their fuel tanks. The existing metal
cleaners-polishes for semis' fuel tanks require vigorous rubbing,
with pressure, to penetrate the grime and corrosion that
accumulates over time.
[0004] It is an object of this invention to provide a metal
cleaner-polish that requires less effort to accomplish its purpose
than metal cleaners-polishes known heretofore. Other objects will
become apparent to those skilled in the art in the light of the
following description.
BRIEF SUMMARY OF THE INVENTION
[0005] In accordance with this invention, generally stated, a metal
cleaner-polish is provided that comprises on the order of 35-44%
mineral spirits (see Merk Index, 9.sup.th ed. No. 6052), 20-30%
finely divided abrasive (such as crystalline aluminum oxide, silica
crystoballite, quartz, or diatomaceous earth, and mixtures thereof,
for example), 5-15% isopropyl alcohol, 5-10% kerosine, 5-10% water,
2-4% Stoddard solvent (see Merk Index, 9.sup.th ed. No. 8602), 1-3%
petroleum oil, and small amounts, (less than 1% each) of
triethanolamine stearate, stearic acid and other fatty acids and
glycerides and sodium gluconate. Mineral spirits, kerosene and
Stoddard solvent are all species of aliphatic hydrocarbons,
derived, as is petroleum oil, as distillation products from
petroleum. All percentages are by weight. Elements of applicant's
composition are found in commercial products: DRX-25 polishing
compound, a product of PPG Industries, Inc., at 19699 Progress
Drive, Strongsville, Ohio 44136; Eagle-1 Metal Polish (Big Rig
formula), a product of Eagle-1 Industries, Box 4246, Carlsbad,
Calif. 92018; WA-300, formerly a product of Global Products
Systems, Inc., 103 East Taylor, Grant Park, Ill. 60940; now
replaced by LC 3567, a product of Jacksonlea, a unit of Jason Inc.,
75 Progress Lane, Waterbury, Conn. 06720, but neither in the
combinations of the present invention nor in their proportions.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0006] An illustrative example of a metal cleaner-polish of this
invention is as follows:
[0007] 41% mineral spirits
[0008] 23% abrasive
[0009] Crystalline aluminum oxide (alumina) 8.0%
[0010] Silica crystoballite 8.0%
[0011] Diatomaceous Earth 6.0%
[0012] Quartz 1.0%
[0013] 13% isopropanol (rubbing alcohol)
[0014] 8.5% water (in addition to the amount in the
Isopropanol)
[0015] 8% kerosine
[0016] 3% Stoddard solvent
[0017] 2% petroleum oil
[0018] 0.8% Triethanolamine
[0019] 0.5% Stearic acid
[0020] 0.2% Sodium gluconate
[0021] For example, three gallons of the mixture, in a large
container, are agitated until the mixture becomes homogeneous. With
the introduction of the isopropanol, the mixture remains in a
substantially homogeneous suspension for three or four weeks. If
some precipitation of solid material occurs then, agitation will
restore the suspension.
[0022] As another example, 128 ounces of DRX-25 polishing compound,
32 ounces of Eagle-1 metal polish (Big Rig formula), 128 ounces of
LC 3567, 256 ounces of mineral spirits, and 80 ounces of
isopropanol are mixed as above. The DRX-25 polishing compound
contains kerosene, cristoballite, a crystalline silica,
diatomaceous earth, petroleum oil, and quartz. The Eagle-1 metal
polish contains aliphatic hydrocarbons (Stoddard type), stearic
acid, and sodium gluconate. The LC 3567 contains crystalline
aluminum oxide, triethanolamine stearate and water, the mineral
spirits (ligroin) is refined solvent naphtha. The isopropanol
(isopropyl alcohol) is in the same form as rubbing alcohol.
[0023] A key ingredient in any formula is the solvent-homogenizer
alcohol. Isopropyl alcohol has been found to be the alcohol of
choice. Ethanol, for example, is not as effective.
[0024] In using the metal cleaner-polish of this invention, it is
only necessary to dampen a cloth or pad with the slurry, and to
wipe the surface to be cleaned. It requires no pressure beyond the
weight of the hand of the user, to clean the surface of a big rig
fuel tank, for example.
[0025] Numerous variations in the composition of the cleaner-polish
of this invention, within the scope of the appended claims, will
occur to those skilled in the art and in light of the foregoing
disclosure. As has been indicated in the Brief Summary of the
Invention, above, the proportions of the ingredients can be varied.
Merely by way of example, the amount of abrasive, particularly the
silica, can be increased somewhat, for example, to 30% and the
amount of mineral spirits decreased, for example, to 39%, and the
amount of isopropanol, to 8%. It is preferred that the variations
in the proportions be in the amounts of abrasives, aliphatic
hydrocarbons, particularly mineral spirits, and isopropanol, they
constituting the bulk of the ingredients, but the other components
can be adjusted within limits. The amount of isopropanol preferably
should not be less than 5%. These variations are merely
illustrative.
