Removing Grout stains from a carpet

[Guest]

I foolishly spilled some black powder grout on the landing carpet, it
was dry (ie, out of the grout bag and hadn't been mixed with water) but
seems to have stained the carpet because it won't vacuum out. Help!

A better vacuum cleaner is all I can suggest.
You could perhaps try one of the dry powder carpet cleaners
(shake-n-vac type things).

if the carpet is 100% synthetic, I'd use an acid such as HCl,
sulphamic acid or similar. But if theres any natural fbre in there it
would eat it for breakfast. A mild slow acting acid would be vinegar
or lemon juice, much safer option but slow. Acids eat cement, which is
what grout generally is.

I wouldn't introduce water into the equation in any form. The grout is
probably black oxide with an acrylic binder, which will give you a much
bigger problem if it's dissolved.

Thanks to all - no success thus far :-(

Having tried what? (and what vacuum cleaner)?

It's a woollen carpet, the grout is black BAL grout. Much dry scrubbing
and dyson vacuuming so far, it's slightly better but still a problem. On
a spare piece of carpet I've experimented with white spirit and water
but (not surprisingly) they didn't help.
I've emailed BAL adhesives in the hope that they can tell me what the
dye is.

If the carpets wool then permanence is a real possibility. You might
just have to go round sprinkling grout on it every 12" in a regular
pattern

Meanwhile you can try the usuals like bio washing powder, oxalic acid,
and oxy-anything.

Reply from BAL:
"To remove BAL Wide Joint Grout Charcoal powder from a woollen carpet,
the use of any liquids or solvents may worsen the situation. As a
consequence, we would recommend using a vacuum cleaner to remove the
powder. As you have already tried this approach with limited success,
then maybe warm soapy water could be used but do try a small
inconspicuous test area first. Alternatively, a proprietary cleaner may
be available which is more suited but it needs to be capable of dealing
with a cement-based powder containing a black inorganic pigment."

Apparently the pigment is either carbon black or iron oxide.

I just spilled brown grout on my lightly colored carpet in my 3 station weight room and thought I was doomed! I vacuumed up as much as I could but the stain remained. I then called a professional carpet cleaner name Randy (Illinois western suburbs-224-805-6556). He came in and cleared up the problem by using a professional vacuum where he could adjust the PSI (more powerful than a conventional vacuum) then cleaned it using 3 professional stain removers. I was relieved that I did not have to buy new carpeting!
