Follow the instructions provided with your chosen mold killer. Generally, apply the product to the grout, spread it evenly, and allow it to sit for the recommended amount of time before rinsing thoroughly.

Can I use bleach to clean grout?

Bleach can be effective in removing mold and mildew from grout, but it can also damage the grout if not used properly. Always test bleach on a small area first and follow the instructions carefully.

How often should I clean grout?

The frequency of grout cleaning depends on factors like bathroom usage, ventilation, and moisture levels. Regular cleaning is recommended, especially in areas prone to mold and mildew growth.

What are some natural alternatives to mold killers?
