How can I remove black stains on a porcelain bathtub caused by clothes
dye? I washed a pair of black jeans and hung them to try over the tub
and the drips caused stains that I've been unable to remove.
So far, I've tried bleach, ammonia, comet and ajax powder cleansers and
TSP, but none have removed or lightened the stains.
Thanks for any help.
I have had luck on a cuple of occasions with DENTURE CLEANER yes
denture cleaner. If possiable try to place the tablet directly over the
stain (braking it up if necessary) and just add a little......bit of
water with a eye dropper or something simmilar. There are also availabe
at I believe LOWES or it may be HOME DEPOT these bleach tablets 1
tablet dissolved in 1gal of water is = to a gallon bleach you could
also try this..try the denture thing first though Good luck
You might try peroxide. I would pour it on a cloth and let it sit on
the stain if possible. If you have Oxy Clean, you might fill the tub
with water to cover the stain and put in Oxy Clean and let it sit
It is hard to imagine a porcelain tub staining to that extent unless the
glaze is worn away - old tub? What kind of dye? Is there soap scum or
mineral deposits in the tuc that are actually stained, and not the
glaze? Hate to ask dumb questions, but glaze should not stain at all.
Could try CLR in case it is actually mineral deposits that are stained.
If RIT dye, they make a color remover but bleach should do as well.
Thanks everyone for these great tips. I'll try them (not all at once of
course) and report back.
To answer norminn's questions, which are not at all dumb:
- yes, it's an old tub, so probably the glaze is worn, certainly
there are scratches on it
- i don't know what kind of dye. the jeans that ran were made by
lee, and perhaps a call to them will be instructive
- i don't think there's soap scum or mineral deposits on the tub as
i've washed and rinsed it too much to leave any soap scum and the water
in my area (nyc) is pretty soft.
Thank you for your excellent suggestions. The first thing I tried was
filling up my bathtub till there was about 2-3 inches of water over the
stain and adding about 1/3 of a bottle of OxiClean Laundry detergent.
In about an hour the stain began to fade. I let it soak until the stain
stopped getting lighter, about 18 hours. Then I added some borax (found
out about that on a web site) and it seemed to get lighter still.
I emptied the tub and thought I'd try Clorex's version of OxiClean's
paste (OxiMagic) as it was cheaper and sold in a smaller container. I
left the paste on the stain for about 45 minutes and more came off, both
by contact and scrubbing.
Then I thought I'd see how Zud would handle what was left. This was the
most amazing to me. Directions said leave on a paste for a mintue or
two, then rinse and scrub if necesary. Quite a bit of the stain was
gone with gentle rinsing. When I applied more pressure it all came off,
even the areas where the dye had colored fairly deep scratches. Not
only that, but unlike the Oxi products, the Zud made my tub shine.
The Zud also picked up the soap scum that the other products missed.
Thanks again for all your help.
