Preventing Mold in the Bathroom
To prevent problems with mold and mildew, keep your bathroom dry and well-ventilated. During and after a shower or bath, open a window or use the vent fan, and use a squeegee or mop to get rid of excess water buildup. Likewise, try to keep the sink area dry after use.
Ideally the humidity in the bathroom should be kept below 55% to prevent mold growth. You can maintain this by ventilating your bathroom well, especially after you've had a shower or bath. Turn on the bathroom fan while you shower and leave it on for about five minutes afterwards to remove the steam and dry out the air. If you don't have a bathroom fan, or as well as using the fan, open the window to let steam out and circulate the air.
Besides leaving the window and door of the bathroom open after having a shower or bath, if you are concerned about the moisture levels you can also wipe down wet surfaces so they dry faster.
Mold can often be found in the shower and the bathtub. Grime from body oils and soap scum which is washed off and onto the shower or tub create a food source for mold to feed on. And of course there are abundant water sources for mold created by the running water and steam.
If you can't get all the mold off grout you can remove and replace the grout. Use a flat screwdriver to scrape out the old grout and then apply the new grout mixture.
