Cleaning Sandblasted Glass with Interior Sealer Coating

The best recommendation Milestone can give is to take the utmost care to keep the sandblasted glass clean, so it doesn't need cleaning.

Another firm recommendation is to not clean the sandblasted glass unless it needs it. Over cleaning can fatigue the sealer coating and result in a non-pristine appearance.

Think of the sandblasted glass surface as that of a piece of fine furniture, use extreme care in cleaning and the products used to do so.

Fourthly, it is important to understand the difference between a surface contaminate that can be cleaned, and damage, that cannot be cleaned. Fingerprints, dirt, dust, and the like, are contaminates that are on the surface of the sealer. Milestone Mfg. recommends first trying to remove such contaminates by lightly buffing the surface with a clean dry cloth. If that doesn't remedy the problem, a light application of an ammonia and alcohol free aerosol glass cleaner can be used. Milestone Mfg. recommends "Sprayway, S-50" glass cleaner or equivalent. The glass should be sprayed lightly overall and gently wiped down until dry. Always start off cleaning as lightly as possible, only getting more aggressive if needed. Aggressive cleaning on one particular spot can potentially create a slight visual difference in that area. Always proceed with care. Also, cleaning too aggressively could damage the sealer coating. Always allow the glass to air dry.

Never clean the seal coated surface with cleaners that contain ammonia or alcohol. Do not use pine based cleaners, or solvents of any kind. The sealer coat, which is a very thin layer of plastic over the sandblasting, can be irreversibly damaged by the use of these products or chemicals. A very mild detergent solution can be used as an acceptable cleaner.

It is not advised to use squeegees, nylon pads, razor blades, scrapers, brushes, or any other cleaning devices that could mar the sandblasted glass surface. Avoid using products that could leave lint or other contaminates on the glass.

Always test any unproven cleaners in an inconspicuous area prior to applying to the overall surface of the glass.

Damage to the sealer coating is typically caused by abrasion, or chemical degradation. A scrape or visual abrasion will not clean off the glass with any cleaner. A seal coated surface that has been compromised by chemical reaction cannot be cleaned off with any cleaner. Re-sandblasting and re-seal coating the glass is the only way to fix this type of damage. Care when moving furniture, or other items must be observed so as not to scrape and damage the sandblasted glass. Also, it is imperative that the correct cleaning products are employed.

Cleaning Sandblasted Glass with Interior Sealer Coating

Cleaning sandblasted glass that has been seal coated with the renewable exterior sealer coating, is much the same as outlined previously. Typically, most surface contaminates will buff off with a clean dry cloth. If further cleaning is required, treat with the Sprayway glass cleaner. The renewable sealer coating is less susceptible to damage as the interior sealer. If cleaning with glass cleaner does not bring the surface to an acceptable appearance, the surface can be retreated with the sealer. Re-application of the sealer removes the old sealer, along with any contaminates, and re-deposits a new coating of sealer which brings the sandblasted surface back to a pristine condition.

It is the customer's responsibility to understand and disseminate all the appropriate handling, transporting, storage, and cleaning instructions to all those in their organization and to the end user of the sandblasted glass.
