Real Simple recommends Scrubbing Bubbles Mega Shower Foamer as the best commercial shower cleaner. Jill Schoff, the author of the book "Green Up Your Cleanup," recommends using a simple paste of baking soda and water to clean shower doors, then rinsing with vinegar.
To clean shower doors, users can spray Scrubbing Bubbles Mega Shower Foamer on all shower surfaces including glass doors, let sit for three minutes, and then rinse. Scrubbing Bubbles products are available in major retailers nationwide.
Individuals can also make their own effective shower cleaner by mixing baking soda with a small amount of water until it forms a thick paste. They can then rub this paste on shower doors with a non-abrasive sponge and rinse the mixture off with vinegar.
