Coffee stain in carpet mat

[74 thing]

I am having a difficult time removing a coffee stain that has been there a while in a carpet mat. I have used Folex with a bissell LGM, tried steam, vinegar, Duragloss carpet cleaner, APC, and a tannin remover, with a brush and shop vac and towels. A little came out but not what I was hoping for a lot better. It is a gray colored mat so the stain is not a light tan color. I would be thankful for any suggestions. The only thing I have not tried at this point is baking soda and hydrogen peroxide, although the Pro's Choice tannin/stain remover does have peroxide in it.

A scoop of oxyclean in hot water in my coffee pot lifts every stain off the sides of the glass, returning the pot to like new condition. Try that if you can.

Seems like you've used a lot of different chemicals, hopefully you haven't set the stain.

If you used APC first, you may have set the stain

I did not use APC first, but the owner did. If that is the case and the stain is set is there anything that can be done or does it just make it very very hard to remove?

if the tanning didn't work then the stain is set.

Keep repeating with the tannin, it will come out.

sure hope the stain is not set. surprised the folex did not get it out.

I'm not sure this will work especially after all you have tried, but I got old old coffee stains out of the seats in my daughter's car using Blue Coral Upholstery cleaner agitated with a microfiber hood on a PC. (The technique was discussed at length either here or on Autopia.) Worked like a charm for me.

another products is called "Browning" it removes the leaching that happens when you wet things.

Flolex might work
