BACKGROUND
The present invention relates to glass and paint finishes. More particularly, the present invention relates to cleaning and protecting painted surfaces and glass surfaces.
Acid rain and minerals cause spots on glass such as on automobile windows, windshields, and painted surfaces which are difficult to remove. One commercially available method of removing these spots on painted and glass surfaces involves rubbing with a piece of clay (see, for example, products sold under the trademark CLAY-MAGIC, US Trademark Registration No. 1,890,761). However, this is a relatively difficult job and is typically only done professionally and not by “do-it-your-selfers.”
Glass, glass windshields, and painted surfaces become contaminated with acid rain and mineral spots and by mineral deposits from rain and other fluid sources. These contaminants are extremely difficult to remove, except by professional treatment. This treatment often involves grinding away the deposits with a buffing machine which uses an abrasive compound. This treatment has a high risk of permanently scratching the surface finish.
It is known in the automotive aftermarket trade that kaolin clay can remove mineral deposits from painted surfaces if properly applied. The prior art method involves dragging a solid block of clay across the painted surface while using a soapy water solution as a lubricant. This prevents scratching and prevents drag, however, the process is difficult and requires a high skill level. If the bar is not rotated frequently, the accumulated contaminant will quickly scratch the finish. It is also a process not lending itself to glass. Kaolin clay by itself will not scratch the glass since the material is softer, but the mineral deposits along with other contaminants picked up by the clay bar are much harder and can scratch.
Kaopolite SF (super fine kaolin clay) has been used for many years in car polishes for painted surfaces.
Fibershield 218, commercially available from Fibershield Industrials, is a coating for aircraft windows to help them repel rain, making it sheet. Fibershield 7525 is a similar coating.
A web site sponsored by PPG tells about their product “Aquapel.” It appears to be the same type of chemistry as Fibershield 218. However, it is applied using a special sponge applicator. The PPG product is for professional use and believed to be a standard water-based product requiring buffing clear. Aquapel makes no claims as scratch resistance nor any claims about treating acrylics (either Plexiglas or polycarbonate).

DETAILED DESCRIPTION
The cleaning system can comprise a clay-based formula including kaolin clay in powder form mixed with lubricants, other cleaners, and delivery agents. This formula is preferably delivered to glass by spraying, using an aerosol foaming propellant.
Before applying the glass treatment system in one embodiment, it is desirable to have a clean, uncontaminated glass surface prior to treatment for the polymer to achieve maximum effectiveness. The foaming clay cleaner of a preferred embodiment can incorporate kaolin clay, combined with sodium bicarbonate and synthetic detergent to clean away and suspend both mineral deposits and acid rain contaminant on glass. The sodium bicarbonate neutralizes the acid rain deposit(s). Chelators (such as sodium tripolyphosphate) can keep contaminant particles from clinging on the glass and re-depositing. The clay frees the mineral deposits. These three things are believed to be the most important ingredients. Additionally, the product can be (and preferably is) an aerosol foam or spray.
The device of a preferred embodiment can safely and easily remove mineral deposits and acid rain contaminants from glass such as auto glass and windshields. It is a mechanism incorporating chemical and mechanical action and differs from commercial buffing so that the procedure and device can be applied by a user without special training, machinery or skills. The device is an easy-to-use unique inverted aerosol foam that clings to the glass prior to treatment and facilitates clean clay with every application. This embodiment is a chemical/mechanical glass cleaner designed to specifically remove mineral and acid rain deposits. And, unlike the clay bar, this is a one-step process.
A smooth surface is in fact microscopically bumpy and consists of micro-sized hills and valleys. Many particles called contaminants have an atomic charge associated with them. Other contaminants such as road film, bug debris, acid rain, animal deposits, etc. have a chemical glue. Both of these mechanisms allow the contaminant particles to adhere to a surface. In one embodiment kaolin clay attacks the bonds of charged contaminant particles. In one embodiment soy esters, acid neutralizers, and surfactants can be included to attack chemical glue bonding. In one embodiment a foam is used to reach particles adhering in valleys in the surface as well as particles adhering to the tops of hills. In one embodiment a sponge 20 (see FIG. 3) is used to work into a surface being treated the cleaning solution along with acting as a receptacle for dislodged contaminant particles.
In one embodiment sponge 20 (FIGS. 1, 2, and 3) is preferably yellow in color and is very cellular in appearance. It is preferably made of polypropylene such as that made by SwissTex in Switzerland and preferably has large pores of about 1-25 mm and numerous smaller pores. Sponge 20 preferably measures about 3×5×1 inches (the measurements of the sponge can vary). In one embodiment sponge 20 is prepared for cleaning using the following method. Soak sponge 20 in clean warm water for a minimum of 3 minutes. Squeeze out water from sponge 20 leaving sponge 20 damp. During use rinse sponge 20 in a warm water bath to keep the sponge clean and remove contaminant particles.

In one embodiment the clay-based cleaning product is preferably packaged as an inverted whipped cream-like foam (preferably with a valve 11 typically used on whipped cream containers—see can 10 in FIGS. 1 and 2) but can also be sprayed upright with a preferably clog-resistant valve. This product can also be sprayed as a solvent-based aerosol. It can be sprayed similar to touch-up like paint or it can be packaged as a thick liquid squirted through a flip-top lid. Additionally, though not preferred, it can be applied as a cream or paste. Preferably it includes a clay/sodium bicarbonate glass cleaner designed to clean away mineral and acid deposits on glass. The glass can be wiped immediately, or the cleaner may be allowed to sit on the glass for a period of time such as between 1 second to several minutes or between 5 minutes to 15 minutes; the glass can then be buffed with a soft cloth for about 10 seconds to 10 minutes to remove the stains. The stains are removed through a chemical process in which the formula reacts with the stains to cause them to stop adhering to the glass.
One embodiment is a system for more effectively delivering glass protectants such as Fibershield 218 and the like. Two formulations have been developed, one water-based and the other isopropyl alcohol (IPA) based. This system preferably sprays on. It can also be a fast drying alcohol based system. Alcohol can also improve the wetting action. The formulas are as follows:

The IPA based formula can use other alcohols, such as propanol, acetone/ketone, and/or ethanol (specially denatured or fully denatured).
Fibershield 218 uses hydrogen bonding to bond to the glass; it polymerizes in about 24 hours, providing a thin film which protects the glass. This thin film lasts several weeks at least, and perhaps even several months. Additional coatings can be applied over earlier coatings.
In one embodiment the method and coating system of the present invention can be used on ceramic tiles and stone containing silicon dioxide (e.g., granite, marble), plastic and painted surfaces as well as glass.
In one embodiment the glass and surface cleaner of the present invention is specifically designed to work with the entire system of the present invention. The cleaner can include special detergents (sodium bicarbonate and non-ionic surfactant) which target embedded deposits in the grooves of glass and glasslike surfaces. The cleaner can help users prepare their surface before the application of the clay embodiment of the present invention and also helps remove the residual clay residue before the shield product of the present invention is applied. A foaming action of the glass and surface cleaner can indicate to users that it is working and can wipe away clean without leaving streaks.

The clay embodiment is preferably used before the wax embodiment. This helps to insure a contaminant-free surface for the wax application. The wax is preferably applied using a terry cloth applicator sponge 30 (see FIG. 6) measuring preferably roughly 5×31⁄2×1 inches (however the size of sponge 30 can vary.) Sponge 30 is preferably made from a towel-like material, such as cotton or a poly-cotton blend, with preferably approximately 50-300 threads per inch. The wax is applied like most waxes and let dry to a haze.
In an alternative embodiment a microfiber towel 40 (FIG. 5) can be used to aid in the removal of wax (and optionally used to remove the clay cleaner after the cleaner is applied with the sponge embodiment). Towel 40 is preferably blue in color and preferably measures roughly 16×16 inches. Towels 40 are preferably made of polycotton or a polyamide blend, with preferably approximately 50 k-90 k threads per inch. Each square inch in towel 40 preferably contains approximately 90,000 microfibers. Unlike ordinary cotton towels that move or push dirt, dust, and other contaminant particles from one point to another, microfiber can get underneath the particles lifting them from the surface. Towel 40 then stores contaminant particles in towel 40, until it is washed.
In one embodiment a wax (FIG. 7) is used which includes a blend of carnauba wax and polymers such as flourinated monomers which polymerize in the presence of water (humidity) and leave a “Teflon-like” protective film. This residual film resists harsh environmental contaminants such as acid rain, road salts, pollution, oils, salt spray, UV light, and the like. The film keeps the surface cleaner longer, enhances shine and brilliance, and helps eliminate fine scratches. The added Carnauba provides traditional water repellancy and shine. The wax can be stored in bottle 60 which can include a push and squeeze type lid which is commercially available.
