Ceramic tiles and grout tend to get dirty very quickly and are one of the most challenging cleaning tasks in any facility. The buildup of dirt, grease and grime in grout is very unpleasant to look at because of the drastic color change that alters the appearance of floors and walls. The way most facilities accomplish this task is with brushes and harsh cleaning chemicals. Some of these harsh chemicals, however, will discolor the grout or will erode sections of it.
A steam vapor cleaner is an efficient, mess-free, and environmentally friendly way facilities can quickly restore grout to its original color. The high heat, low moisture and gentle pressure from the steam forces the dirt out of the grout and brings it to the surface where it is easily wiped away or extracted.
There are some exceptions where steam cleaners are not the solution, however. If the grout is sealed, steam will not get the dirt out from under the seal. Also, old, broken grout, where holes and cracks are visible should not be steam cleaned. Grout erosion is usually the result of a chemical reaction from the acidic cleaning agent that was previously used. In those cases the grout should be replaced.
