Shower Door Cleaning Tips

Soap scum builds up on shower doors as the result of the paraffin that's used as a binder in bar soap. Over time, the combination of the soap and minerals in the water create a waxy film on the doors that's difficult to remove. Hard water can make the problem even worse. Experiment with various solutions to find one that works best.
Step 1
Use a commercial soap scum remover. Use the product exactly as directed. Understand that multiple applications may be required at first to remove built-up soap scum. Follow with a shower spray to prevent future build-up.
Step 2
Attack the soap scum with straight household vinegar and a net-covered sponge. Apply the vinegar and scrub, working from the top of the doors down.
Step 3
Mix 1/4 cup of household ammonia with one quart of tap water in a clean spray bottle. Spray the solution over the soap scum and scrub with a brush or nylon scrubber. Rinse well and dry with a soft cloth.
Step 4
Remove the shower doors. Apply automotive rubbing compound to the soap scum. Use a power buffer to remove the soap scum. Rinse and dry the doors well and reinstall.
Step 5
Take preventive measures. Wash the shower doors with a little shampoo before exiting the shower. Rinse the doors well and use a squeegee to remove the excess water.
Step 6
Wipe down the shower doors weekly with lemon oil. Apply the lemon oil to a soft cloth and wipe over the door and trim. Turn the cloth and wipe away any excess.
Step 7
Prevent soap scum by using liquid soap instead of bar soap. Purchase liquid soap by the gallon and pour it into a smaller pump container for the shower.
Tips and Warnings
Do not use abrasive cleaners or wire brushes. They will scratch the shower doors.
Make sure the room is well ventilated when working with ammonia or cleaners that contain ammonia.
Do not combine ammonia with any other any other household chemicals, especially chlorine bleach. Toxic fumes can result.
