Best Cleaner for Granite Tile shower with nasty grout

Hi All,

Can anyone give me a recommendation on what I can clean a granite tile shower with that will disinfect the grout without damaging the tiles or ruining grout?

Preferably something generally available, as I need to do this fairly quickly.

The grout lines are pretty nasty at this point...

Thanks!

-Dylan

Hi Dylan,

Are we talking about soap residue or mildew ?

Hi Michael,

Unfortunately both- soap residue on the tiles and mildew on the grout seams...

Hi Dylan


Can you post a photo? I'm concerned about where the mildew is coming from. The shower stone & grout can be cleaned with a tile and stone specific high alkaline cleaner (such as Stone Techs KlenzAll ).

more info

As far as the mildew is concerned- I probably overstated the seriousness of it. Pretty sure it's not indicative of bigger probs- it's just been a long time since it was cleaned- a few little moldy/mildewed areas have formed in a few of the grout joints. It's a fairly new shower (maybe 3 1/2 years old).

Not sure the type of tile- it's a mixed grey color (mauve according to a box I found in the garage).

Having trouble uploading my photo, so can't seem to post.

Just looking for general cleaning guidelines so I dont mess anything up ;-)

Thanks,

Dylan

Hi an,

Sounds like you have Almond Mauve. For this one do as Doitright says then follow it up with a an impregnating sealer.

do it right, has it right!

Clean with the Stonetech Klezall - alkaline cleaner. But also get some Revitalizer - neutal cleaner as well to neutralize the alkaline cleaner. Just spray it on and wipe it off. Now your sealer can bond correctly with the surface, when not neutralized it wont be as effective.

Cleaning tip. Use a plastic bristle scrubb brush while wearing gloves and googles to get the max effect from the cleaning agent.

Hi Darrel

Neutral pH cleaners will not greatly affect neutralizing the alkaline much more than plain water. Revitalizer actually has a small amount of sealer in it. It is more critical to neutralize when working with Restore which is acidic. It's always critical to neutralize the acidic surface as it will eat away at the sealer.

If you're not around marble or acid sensitive materials, we will usually follow the alkaline cleaning of grout with an acidic cleaning. This will also effectively neutralize the surface.
