Any advice please.
On thursday I was called to a house where a rather large dog had messed in a number of places during the night and the customer had attemped the clean herself finishing with Marks and Spencers Carpet and Upholstery wipes.
I first used Solutions number 3 spotter and removed a fair degree of soiling which cleaned most of the stains leaving me with two larger stains which although reduced would not shift any more.
I then used Stapros double hit enzyme product and cool HWE extracted, and repeated this in varying strengths and appeared to get a 95% clean, which my customer appeared to be happy with and the carpet was left nearly dry and appeared to be dry when I revisted the customer later that day.
This evening my customer rang me so say the stains have dried brown so I will be recalling there tomorrow.
I am reasonably certain that this is not browning as the carpet has a strong synthetic rubber backing and hessian or a natural backing is not evident
The carpet is an off white fluffy synthetic fine and deep pile. (it looked like wool and something like Acrilan, I could not detect a hair smell in the burn test.)
There is a large piece of spare carpet that I can probably test to destruction and also take round to some knowledgable carpet retailers to see if they can actually identify the product and it's make up.
Help or advice would be much appreciated
Regards
