Why Grout Lines Resoil So Quickly

I often get this question, "I cleaned my grout a few weeks ago and they are already dirty, why does this happen?"

Well there can be several reasons for this but the most probable answer is that you really never got them clean. Grout is very porous and therefore absorbs soil very quickly. What usually happens is the homeowner will put some general purpose cleaner on the grout, scrub it in with a toothbrush and then wipe it off with a towel. Well as you can imagine, most of the soil and cleaner was absorbed into the grout and as the cleaner evaporates the soil wicks to the surface.

Other reasons are: You left a residue on the grout and now it is a magnet for dirt, or a process caused efflorescence to take place where salts from the grout rise to the surface, or you removed the topical sealer thus exposing the grout to rapid re soiling.

Remedy: The only true way to clean the grout is using a professional tile and grout cleaner who uses a high pressure, high heat cleaning method followed by adding a reactive sealer. If you are a do-it-yourself er I recommend using a general purpose cleaner, agitating it into the grout and then rinsing with a Hoover Floormate or similar machine.

Hope this help,
