How to Clean Moldy Caulking

Lately we’ve been discussing how to clean and maintain marble surfaces and grout. (“Don’t Take it for Granite. How to Avoid Damaging Fine Stone Surfaces.” How to Clean Marble Grout”, and “Top 5 Tips to Prevent Mold in Showers“)

Mold is clearly a concern that surfaces. In fact, Dan Lundstedt from Sir Grout cites mold as the number one reason people call his company. He  offered us some more tips, this time how to clean moldy caulking. His tips apply for caulking in any bathroom, whether there is marble or not.

Dan: Make a mild bleach solution by mixing one part bleach to five or more parts water. Wet a soft cleaning cloth with the solution and wipe the caulking. Let it set for a few minutes after application, then rinse.

Unfortunately moldy caulking turns into an uphill battle. Once mold forms on caulking it will generally keep reappearing until the caulking is replaced.  The more you clean it the more it gets compromised, and it is more susceptible to mold.

Never scrub caulking because it will break the seal, which may lead to water damage. Moldy caulking that will not come clean may need to be replaced. Caulking does break down over time and typically should be replaced every two years.

Maid in Chicago: The Center for Disease Control (CDC) recommends cleaning mold with a bleach solution of no more than a cup of bleach to a gallon of water. This is the equivalent of filling a 32 fl.oz spray bottle with water and 2 oz. of bleach.

Caulking is a do-it-yourself project many home owners can tackle themselves. However, if you would prefer to have a professional handle it, contact Dan at Sir Grout:
