Stains appearing from no where

Huh Huh Huh

Cleaning a wool rug today black with cream design, no visible staining (no backing also no visible staining) done the usual tests, every thing ok, applied pre-spay (wool safe agent) left it to dwell, plain water extracted. Then I notice in certain areaís mainly around the corners a Greene brown and pinkie colure appearing together and in others just pinkie.

Any ideas?

Only come across similar thing once before Shocked
Rug had been left on stone flooring whilst the housekeeper had mopped floor........hence the edges and corners had weak colours due to ammonia/bleach in floor cleaning product Roll Eyes You cannot check whole rug for test but check PH on the bad areas and check the placement of the rug for what may have been used to clean around it. Laminte may mean soapy edges, Stone may mean bleached edges and white carpet may mean
that it has not been moved when carpet was cleaned at some time Huh

Hi Len

I have not come across this problem and I have to bow to Chris's previous experiences somewhat.

Check the pH of the Woolsafe product that you used, I think you may find it slightly alkaline... it may be worth a try and use the alternate pH on the acid side to see if it will reverse.... no promises.

In this trade the accepted 'neutral' for pH levels is 5.5 to 8.4

The BSI test 'ranges' I saw used were 5.5 to 8.4

However when the BSI tests are carried out they are precise... and neutral is 7 †(not 6.9 or 7.1)

What this said to me was that if we extend the pH ranges beyond that of the BSI test ranges then we are in a 'risk' area.

Hi Chris

Tests are going well but saying that the pinking still remains. I will certainly keep all informed. I have a feeling that it urine which I canít smell! The customer is adamant nothing is towards? But I have my reservations probably see them in court.

Sorry to be personal what part Surrey (big county as is Kent/London) do you cover as Iím some times ask to go to your neck of the woods, and have to bale out, which I donít like! I donít have any contact Surrey even that it local to me (kent)
