EnviRestore Glass Stain Remover is a restorative cream that removes stubborn stains from glass surfaces, and is most commonly used to remove stains that have not damaged the surface of the glass such as: waterproofing overspray, oils, soap scum, light stains, and caulking residue.

In situations where stains have damaged the surface of the glass, we recommend Glass ReSurfacer Final Polish.


This product effectively removes what is commonly referred to as stage 1 corrosion as well as stains caused by mineral deposits, including calcium, lime, magnesium, rust, salts, efflorescence and high mineral content tap or well water. This solution also removes damage caused by soap scum, oils, acid rain, adhesives, water repellant overspray and/or leaching, caulking or coating residue, exhaust fumes, everyday grime and buildup, and other stubborn stains from architectural glass surfaces without the use of machinery. This product is an effective preparatory measure when using Presto’s Glass Defender, invisible glass protection.

This product is formulated for use on plate or tempered glass surfaces, but will often work on aluminum and other exterior architectural surfaces.

This product removes stains caused by foreign materials from the glass surface, but will not repair damage caused to the glass surface as a result of corrosion. Product may cause minor scratching which can only seen when glass is viewed in direct sunlight. To avoid this, use Presto’s Glass ReSurfacer® System in order to remove all types of glass stains and repair damage.  The Glass ReSurfacer system produces optical distortion-free results.

Clean surface prior to use. Remove dirt or sand which may scratch the glass. It is extremely important that the application pad or towel used with this product is not contaminated with abrasives. Always test in a small, inconspicuous area in direct sunlight prior to use.


Apply this product to previously cleaned surface with a sponge, white, non-abrasive pad or a soft towel. Apply a small amount of product to the applicator. Agitate the product on the surface until the stain is removed, wiping away any excess residue. Do not use excessive pressure or minor scratching can occur. To remove oily stains, apply product and allow the product residue to dry to a white powder. Remove the white material by using a dry towel or white, non-abrasive pad. Do not inhale any dry dust from this product. In some instances, a second or third application may be required. If Presto’s Glass Defender will be applied after the restoration process, DO NOT use or oily detergents containing surfactants to clean the surface.


Even though this product is designed to be an employee safe alternative, we recommended limiting bodily contact with any cleaning product. This product may cause minor scratching when too much pressure is applied or when used in conjunction hard pads or a motorized polisher. While these results may be acceptable, it is best to perform a test area in direct sunlight so that both contractor and client are aware of the outcome.


Following restoration, we recommend the use of Presto’s Glass Defender to seal the glass and preserve the finish for up to 5 years.

Stone Protection Prevents Glass Stains

When removing stains causes by mineral leaching from stone surfaces such as concreter, precast and GFRC, we recommend the use of Leach Stop Mineral Leaching Mitigation Treatment to order to help to prevent further staining on the glass after the glass restoration process.
Glass Protection Prevents Glass Stains
After removing the stains from glass surface we recommend the use of high performance glass protective treatment such as Glass Defender to create a silicone hybrid polymer coating on the newly restored surface. In the future if and when contamination comes in contact with the glass the polymer barrier will allow the stains to be removed much easier than the glass surface.

Proper Window Cleaning Prevents Glass Stains

The use of high mineral content tap water and improper window cleaning detergents help to cause glass metal and stone stains. Clean only with deionized water to preserve the glass restoration investment.
