There may or may not be need for alarm. If it is just haze wipe it
down with a wet sponge, rinse and repeat several times. Haze will
probably stick around for a couple days. Many washes are needed to
completely get rid of it off most tiles.
If it is excess grout and dried to the surface of the tile, call the
tilers and tell to too look at it. It may be a s severe as having to
replace the tiles or using a chemical like sulfamic acid to remove the
excess grout. Sometimes, and I admit in a lot of cases, a piece of Oak
wood,a small strip, use it like a scraper and it will remove most dried
We had tile installed about 4 years ago, so details are fuzzy. I
assume you have glazed tile. We were instructed to wait a certain
interval, then wipe tile with vinegar/water mixture. It is important to
do it right, as it can become difficult to remove. Call your installer
and ask them how to remove it, and when/how to seal the grout. We had
large tile with wide grout joints - installer told us ok to walk on it
with shoes on (no toe prints in grout :o)
my installer said just to wipe it off with a damp terry cloth, rewetting the
cloth as i go. a friend who is an installer said to buff it with a
scrubbing sponge, then vacume up the dust. seems like everyone has an
opinion! i took my installers' advice and some came up. some is still
there. i guess it takes a few wipes.
If you can take an inch of haze off by scraping it with your fingernail
then it is an easy fix. First, wet a clean sponge and pass it over the
tile, rinsing often to keep the sponge free of grout. Make about 2-3
passes across the tiles until the haze almost looks gone when wet.
When the tiles dry (less than an hour), you will see a light haze that
you can then use a light grade steel wool pad to buff across the tile
to remove the remaining haze. If the haze is really light, you can
buff it off with a towel instead of the steel wool (almost like
removing wax from a car).
Your installer is an idiot. Tell him to clean the haze off
himself. It's not your job. An installer should leave the
new floor spotless- if he claims to be an expert.
If your plumber tiled it on the weekend-----that's another
But since he's an idiot and you'll probably have to do
it yourself anyway, just mop the floor for a good 10 minutes
with a solution of about 10% vinegar, slopping it around
liberally, then rinsing and mopping it up. It won't hurt
the grout. If that doesn't do it, a tile dealer will sell
sulfamic acid, which is a "safer" acid than muratic.
It comes in crystals (like sugar) which you dissolve
in water per instructions on the can. Slop it around as
I described above and rinse it well. That will remove
any grout haze.
Time is your enemy now as grout haze (usually a polymer
film) gets harder day by day so act soon.
Since you said some of it came off with water and
a towel, I'll bet it comes off with the vinegar rinse.
