If your glass block shower wall has recently come under attack from mold, mildew, or other shower-related grime, you may be curious about how to properly clean it. Fortunately, the glass block is a simple material to clean. Much more so than traditional shower tile.
Clean Your Grout First
Clean your grout before cleaning your glass block shower wall. Lightly soak the bristled end of a toothbrush or a small scrub brush with an abrasive commercial cleaner and gently scrub away the grime. When cleaning the grout, try not to put forth an excessive amount of elbow grease, as you'll want to avoid chipping away at the grout. Once you have fully purged the grout of filth, use a spray bottle full of water or a damp, non-abrasive cloth to rinse off the cleaning solution.
Use Mild Soap and Warm Water
When cleaning your glass block shower wall, use a homemade cleaning solution of warm water and mild liquid dish-washing soap to remove dirt and debris. Lightly soak a nonabrasive washcloth in this solution and wipe your wall in a circular fashion. Do not exert too much pressure on it.
Treat Any Mold or Mildew
When dealing with excessive mold or mildew, use a homemade cleaning solution of .25-cups of white wine vinegar and 1-cup of water. Once you've finished cleaning, rinse your solution in the same manner as you would the nonabrasive cleaner.
