How to remove some stains
« on: October 29, 2005, 05:32:06 AM »
ATTENTION PLEASE: THIS IS A SERIOUS PROBLEM. ;D

I found some yellow stains on one of my white coats. In my opinion, it may be Fe2(SO4)3 or something containing Fe.
How can I remove it? Especially because it is in a rather embarrassing position.

PLEASE HELP ME!

If it is iron, try citric acid, or DILUTED phosphoric.

If it doesn't help, splash some coffee on the coat in different places, at least the embarassement will disappear :)

Fe2(SO4)3 is soluble in water! I think that your stains are iron oxide (Fe2O3)..in this case try diluited HCl (2mol/L)....If it doesn't work "clean" the stains with a pair of scissors ;D

I've used citric acid on stains before. Just take an lemon. It worked for me. I've been told limes work also.
