Grout stain stain

[Derek Atlanta]

A couple of questions...

If I left a little stain residue along the grout lines in a couple of places on my porcelain tile, is there something I can do to get it off without damaging the stain on the grout?

Also, what is the best way to stain a grout line that adjoins a painted sheetrock wall? Do I just use blue tape on the wall?

Hi Derek

How much excess are we talking? Thick? Right on the edge of the joint?

Do you think you can get at it with a razor?

If not, you can use a solution of 1 part ammonia to 10 parts water (or so…no science here). Let it dwell a few minutes, then use a green scrub pad and try to cut it in. Any softening of the stain will cure out, and re-harden, upon evaporation of the ammonia solution.

Yep, blue tape. I don’t use it myself, but I recommend it. After so many years of cutting in baseboard, carpet and such, you get good at sponge control and real fast with a clean, wet terry towel.
