Keeping your bathroom in good shape and preventing mildew involves more than just catching leaks and ensuring your shower is spraying in the right direction. The very presence of water is a great environment for the growth of mildew or mold. If you've just had your plumbing redone and remodeled your bathroom, you'll still have to contend with keeping mildew off of places like your shower curtain. Here are three ways to take care of that detail.
There are commercial sprays available (usually a mixture of vinegar and other anti-mildew cleaners) that you can spray on the curtain and the rest of the tub (or stall, if all you have is a stand-up shower stall). Use the spray after each shower or bath and let it air dry. You'll still have to manually clean the bathroom on a regular basis -- the spray won't take care of all dirt -- but the spray will make it easier and it will keep your newly fixed bathroom looking a lot better.
Salt and Scissors
Apartment Therapy had an innovative and cheap way to prevent mildew if you've had to go and buy a new shower curtain. When the curtain is new and unused, soak it in salt water. You'll have to do this for "a few hours," as well as let it dry completely before using. The site also suggests cutting the bottom of the curtain (if it's a plastic liner and not a decorative cloth curtain that could unravel) with pinking shears. These cuts will increase the ability of water to run off the liner instead of sitting at the bottom and feeding mildew.
This is likely the cheapest but most attention-intensive option. After you finish your shower and get out of the stall or tub, extend the curtain as far as it will go so that there are as few pleats as possible. Open the bathroom window or turn on the ventilation fan. When you're done doing things in the bathroom, set a box fan or table fan in the doorway and aim it at the curtain. (Do not set the fan on the floor if it's wet! Set the fan on a stool, a book, or a dry patch of carpet just outside the bathroom door.) Occasionally go back into the bathroom and shift the curtain to ensure all parts of the curtain get exposed to the air. When the curtain appears dry enough, move it outside of the tub so that the very bottom of the curtain gets some air, too.
If you find that you're still having issues with mildew appearing, you may want to call plumbers back to take another look at the shower. It could be there is a small leak still causing extra water to seep out somewhere. Contact a business, such as Roto-Rooter Sewer & Drain Service, for more information.
