Preventing Mildew behind Caulk Preventing Mildew behind Caulk
If you notice mildew stains behind caulk, do not waste your time and money shopping for cleaners because you cannot remove them. The only solution would be to remove the caulking and replace it. The level of difficulty in taking them out would depend on the kind of caulk that was used in the construction. Hence, mildew must be prevented from growing in order to save your caulking. Mildew grows very well in bathrooms since the water and moisture makes it the perfect breeding ground for them. However, there are some things you can do to prevent them from overwhelming your bathroom.
Step 1 – Rinsing Your Bathroom
After bathing or doing other bathroom functions, rinse the walls and other areas of the bathroom that has caulk in it with water. This is necessary in minimizing oil and soap residues. This can take some time but you have to prevent mildew from getting a foothold.
Step 2 – Drying Your Bathroom
After taking a bath, leave the doors or curtain of your shower enclosure open so that the area could dry out more quickly. Turn on the vent fan for your bathroom and let it run for around 5 minutes. If you do not have a vent fan, it would be a good idea to have one installed, no matter whether your bath has a window or not. In addition, almost nobody would open a bathroom window.
Step 3 – Painting your Bathroom
The bathroom should be painted with a glossy paint. If it is painted with flat wall paint, it would be more attractive to mildew growth. Be sure to add Mildewcide to the paint before applying it.
Step 4 – Cleaning Mildew Prone Areas
To clean areas that are prone to growth of mildew, add 1 quart of bleach to 3 quarts of hot water to make 1 gallon of cleaning solution. You can then add 1/4 cup of a detergent powder of your choice together with 1 cup of tri sodium phosphate. Use the solution in cleaning your bathroom and in killing mildew and its roots.
Step 5 – Removing Caulk
If mildew had already overgrown a caulked area, remove the caulking by scraping it off with a scraper, utility knife or razor blade. Scrape off a little of the caulk at a time since removing it all at once has the danger of scratching the surface. Wear a heavy glove for the task to avoid cutting yourself. If it is a non acrylic caulk, you can peel off most of the material by putting a wet rag over it for a number of days and letting it swell. If the caulk is acrylic, lift it off the tub or tile easily by applying a 90 percent isopropyl alcohol. If it is silicone, you might have to contend yourself with scraping it off slowly but you might weaken the silicone by applying strong chemicals that are alkaline.
