Mysterious

[Cairnswun]

I encapped a nylon (NOT SDN) carpet the other day.

Two days later the owner phones and say's there's a problem.

Could not see anything during pre-inspection, but it now looks like the color has been bleached out.

Any ideas what it may be.??



Ta,

Shorty.

Sorry to see you're dealing with this Shorty. Possibly there was a chemical residue in the carpet from before your cleaning. And perhaps your cleaning activated the old residue. This can happen sometimes. Bathroom cleaners, bleach, pool chems, acne medicine - are a few of the possible possible culprits. If it really is a bleach spot, as it appears to be, the spot would need to be dyed. CTI has some good stuff for this... http://www.proschoice.com/html/color_mod...etics.html

Thanks Rick, I thought the same.


I took the photo.

I then rinse and extracted the area with no change with my spotting machine.

The Lady assures me that nothing was done to the carpet.

There had been water damage in two areas where there was a slight browning in the typical wave pattern in a semi circle, these had been sprayed over with Chemox and buffed.

( Chemox would be similar to Hydrox. Chemox is a product that contains Hydrogen Peroxide. From the MSDS: Chemox is used as an additive for specialised Sonitron Detergents to improve performance. )

In both areas the browning was removed.

The marks were outside of the area that was sprayed.

As both areas were so small, the Chemox was added to a 500ml trigger sprayer and filled with water in the adjacent bathroom.

50ml Chemox to 400ml water.

Correct spray pattern was adjusted in the hand basin prior to application.


After buffing, the entire area was then encapped.


Thanks for your replies.





PS:: As this was up two flights of stairs, the Chemox was added down at the van, so no spillage, etc;
