steam-cleaning products
Aside from using old toothbrushes to scrub tile grout, homeowners can also use steam-cleaning products that are effective in restoring tile grout to its original look. However, homeowners should take extra precaution in choosing steam cleaning products. Some of them may be harmful for colored tile grout. Homeowners can also save some money by coming up with their own ceramic tile cleaning solution. To do this, they just have to mix ¼ cup of low sudsing, all purpose ceramic tile cleaner, one cup of ammonia and ½ gallon of cold water.
