To remove build up and mildew from the corners of your shower, spray the dirty areas with vinegar, and let it dry. Then spray again and wipe clean. The mild acidity of vinegar loosens the particles and kills bacteria. It’s much easier to prevent mold than to clean it, so it’s a good idea to spray down the shower after each use with a mixture of water and vinegar to prevent mold from settling in the first place.
A scummy plastic or vinyl shower curtain can be cleaned in a number of ways. If it’s not too bad, simply spritz it with a vinegar and water solution, then wipe clean. You can also wipe curtain with a damp sponge and baking soda. For tougher build up or mildew, you should take the curtain off the hooks and lay it on a flat surface so you can scrub it clean. You can also toss the shower curtain in the washing machine. Instead of your regular detergent, use 1/2 cup of baking soda and a few tablespoons of vinegar. Make sure to throw a couple towels in as well, to help rub the grime off.
