Removing Mortar Residue

• 1). Wash your hands thoroughly in warm or hot water with soap to remove residual mortar from your hands. Cleaning the blocks with mortar-covered hands only makes the problem worse.
  
  
• 2). Dampen a sponge with warm water. You do not need to add soap to the sponge to clean up the mortar.
  
  
• 3). Wipe the glass surfaces with the damp sponge to remove the excess mortar. Turn the sponge regularly, or replace the sponge, to ensure that you always have a clean area on the sponge to work with.
  
  
• 4). Buff the clean blocks with a clean, dry rag. This removes any streaks or smears left behind from the sponge.
  
  

Removing Silicone Residue

• 1). Dampen a clean, dry rag with lacquer thinner or denatured alcohol.
  
  
• 2). Wipe away silicone residue with the damp cloth. The cleaning products will help dissolve the bond between the caulk and the glass. Turn the rag regularly, or replace the rag as needed, to make sure that you always have a clean area on the rag to work with.
  
  
• 3). Buff the clean blocks with a clean, dry rag to remove residual cleaner and any streaks or smears left behind by the rag.
