Yellow stain...origin unknown
#1
I have a commercial carpet that has a 12 inch yellow stain that I am not sure what it is. No pic but it is light yellow on a gray carpet.

Any ideas on removal?

Thanks

If you dont know what stain then it will be tough to give any advice.

I just test different products on unknown stains.
test a solvent on cloth to see if there is any transfer
test a product to loosen -----spot and boost or spot and boost green---helgel----or other emulsifiers you have

test reducing agents----redvanish
test oxygen products.

Test means small area apply product and ----- WAIT-----not many yellow stains come out fast

You can speed up oxygen with heat or UV
You can speed up reducing agents with acid but i probably would not try that on a yellow stain on carpet

Read the stain removal guide on vacaway---http://vacaway.com/vaSpottingGuide/SpottingChart.pdf

I wonder if it is where a plant used to sit. I've never been able to remove those stains from where they water plants and it leaks through to the carpet.

Is it a perfect circle, does it look like a splash?

It looks like a spill. Has a tail and some drips. They are African so maybe a curry?

Test  peroxide with steam or uv light?


problem b gone  accelerate with heat


or ammonia and peroxide accelerate with heat


Red vanish may improve stain after 24 hours not fast working reducing agent unless you are working on red.

All of these products will take all color off fiber if you use too much or heat too long---needs small amount on fibers and you must carefully use white rag to transfer stain onto rag.

procleaners tomorrow night on stain removal---ask  about your stain

What is the carpet fiber??

Some fibers can yellow when exposed to chlorine bleach.

I.D. the fiber first, then concentrate on what may have caused it.

Check the cleaners cupboard in a commercial property.

I agree ---Could be bleach

I have seen some commercial solution dyed nylon that did go light yellow--white because of bleach. Most commercial carpets do not but some do.

Try to buy some paper test strips at pool supply that test for chlorine and ph---testing stain you may need to wet fiber then press strip on yellow

Test fibers first
Invest in your business and take a carpet class for fiber id and stain removal it is worth it.

Patch looks good.
