I just bought a house, and in the master bedroom bath the standup shower has a serious mildew problem. The shower is a one piece fiberglass unit. What is the best way to remove the mildew and scum stains? The mildew is also on the sliding shower glass door. My fix for that is take it out and put in a new one.
This is a dual problem. To correct the mildew, first apply a solution of 50%/50% bleach and water with a few drops os detergent to all the surfaces (I keep a spray bottle with this mixture for maintenance). Let it set over night. The bleach (much cheaper and better than the commercial products sold for this) will kill the mildew. Rince this off and then apply a commercial soap/scum removal product. Let this set for 15 or 20 minutes then scrub down with a nylon scrub pad and brush for the corneers and around the fixtures. You may have to repeat this proceedure. I use the bleach mixture on a monthly (it's so easy. The last person to use the shower for the day sprays when they finish)basis to make sure the mildew does not reapear. The soap/scum is used on an as needed basis. This is a lot easier and much less exoensive than replacement. GOOD LUCK Bill
