Friday''s Ask the Experts question from a cleaning professional on the International Custodial Advisors Network
(ICAN) "Ask the Experts"
page: Every time I research and look for a way to get dirty grout clean, I find there are many different answers. But, when I try the methods, they hardly work. What can I use to clean grout, and what steps do I follow?
There are two problems with cleaning grout. One is that it is recessed below the floor level, making agitation of a cleaning solution harder, and two, it is porous unless sealed and allows soil to sink into it.
Even so, it should not prove true that all the methods you try "hardly work."
Apply a solution of detergent or degreaser, depending on the type of soiling the floor experiences, agitate with a brush (not a pad) that will reach down into the grooves... — Lynn E. Krafft, ICAN/ATEX editor
