Cleaning

Cleaning can be done as for ordinary glass with non-alkali window cleaner; afterwards rinse with water or clean with denatured spirits and/or wipe with non-abrasive clean cloth or soft tissue. Avoid harsh cleaning materials such as scouring powder, steel wool and cloth with course metal treads in the weave or other sharp instruments; avoid also cleaning agents containing ammoniac, acid, silicone or fluoride, dishwasher and general purpose cleaners.

Handling

GroGlass Sapphire physical qualities are similar to uncoated glass. Therefore, handle it with the same care as ordinary glass to avoid breakage or damage. Special precautions need to be taken to protect the surface from sharp objects, abrasive and adhesive surfaces.
If repacking, keep the glass dry and wrap in acid-free paper at all times (thus protecting glass from scratches caused by glass rubbing against each other, chemical stains from paper, etc).

When transporting, keep the glass in a vertical position, basing the glass panes on the longer edge.

When storing, keep the glass panes dry, separated by layers of acid-free paper so that no moisture can penetrate the packaging.

When labeling, use only acid-free adhesive stickers.

When cutting and processing glass, make sure the working table and instruments are clean and free of splinters.
