Tile countertops may look really great when they are clean, but they can be really difficult to keep that way. Getting rid of dirt in the grout between your countertop tiles can be a chore, but mixing baking soda and vinegar to clean the grout can work wonders.
Pour a little baking soda on the grout, then a little bit of vinegar. Watch it make a little volcano as the baking soda and vinegar mix together. Combining these products will get the dirty grout nice and clean.
Scrub the grout stains with a used fabric softener sheet. You will see it clean immediately or after a few minutes, depending on how dirty your grout is.
Rinse it out well with water. Repeat scrubbing with the dryer sheet if necessary.
Let the area dry well before you place anything on your countertop again.
