To start you will need some of the following:
- Toilet cleaner
- Scrub brush
- Microfiber cloth
Always test all surfaces before using the cleaning product of your choice. The best way to clean grout is to pour out some of the toilet cleaner in the grout lines in about a 10 square foot area, set a timer for about 5 minutes and let the toilet cleaner sit on the grout. Make sure any of the toilet cleaner doesn’t spread into a carpeted or wood area.
Once the five minutes is up, use the scrub brush to go over the area, reset the timer for another two minutes. At the end of two minutes give the grout one more quick scrub down and then wipe the toilet cleaner away using a wet rag or microfiber cloth, Keep working your way around the room just doing small areas at a time. When you are completely finished let it all dry and check for any spots you may have missed or need to go over again.
