Remove mold/mildew from caulking in shower?

Kris
by Kris
We have a bathroom in our rental that hold moisture. I've used bleach, I've scrubbed, I've used vinegar and baking soda but the shower continually builds up layers of soap scum and mold / mildew. Is there anything else I can try?

    You need to clean away the old caulk, then clean with some bleach...let dry well then re-caulk. Once you have this "clean slate" then more frequent cleanings to remove soap residues. You need to break the food water growth triangle. This article I wrote covers grout but caulk issues are very similar http://www.networx.com/article/start-cleaning-tile-grout-more-easily

    They have some little handy Caulk remover tools that will get rid of the mildewed caulk. Once caulk has mildew in it, I don't know of anything that will renew it to pretty. Just redo it and get it over with. I've heard that spraying some Tea Tree Oil mixed with water will keep mildew from forming. Also, make sure your shower area doors are adjusted to let air into both sides at once - ventilation is a good preventer.

    after it is cleaned try using some pledge on it coat it very well it keeps the moisture from sticking you will have to reapply when you see water sticking instead of running off xx
  • The key to stopping most molds is to control dampness.The worst infestations usually occur in damp crawl spaces, in attics and walls wherewater has leaked in from the outside, and in basements with poor foundation drainage. Stopping leaks, ensuring good ventilation in attics, keeping crawl spaces dry and routing water away from the foundation are the best defenses.

    I had an awful job cleaning all the mineral deposits and soap scum in my shower, I used the blue Dawn and vinegar mixture popular on Pinterest to clean it all. I had to remove the caulking and replace it because of the mold. Once done I put a coating of Turtle Wax (used to polish cars) on everything and buffed it . It has lasted a long time with just a regular wipe down. Hope this helps.
