Today i used jacquard decolourant on a oriental rug to fix dye bleeding. It worked really very well. I think jacquard decolourant is stronger than sodium hydrosulfite

Probably the same thing as Masterblend Magic Powder.
I got a reminder of my first experience with magic powder today... yep your turmeric stains have gone!

you never truly forget the awkwardness of the first time :shifty:

Jacquard decolourant and steamer work very well together. However I ask you a question. After reducing red, I see the color of the white wool tending to green. How to eliminate this light green reflection from white wool?

Is it a ph color shift? Then adjust the ph.

Or, did you strip some color out?

If color got stripped, then add back the missing color with dye.

Grey/Green is good
  1. Apply a bit of a detergent that is slightly alkaline pH 9 to 10
  2. Let it sit for a minute or so and then rinse off.
  3. Then apply some acid rinse at 1:10.
  4. It may turn pink again. then rinse that off and re-spray with your detergent.
  5. It will turn grey/green again but should be a lot lighter than before.
  6. Re-apply the acid rinse and it will again turn pink but each time it should be lighter than before.
  7. After 2 or 3 attempts with that leave it with the acid rinse on and you should most likely find that it's gone by next day.

Ponint 1: should this process be started on dry carpet?

Google search says the following:

wool in 50 c.c. water for 12 hours, is usually between pH 8 and 10.
