Title: What could these marks be?

Hi guys,

I cleaned these carpets on 30th August - an end-of-tenancy clean. Can't remember what they were made of.  Customer has just sent me these photos as their agent is not happy and they think it is a chemical mark. (I thought I had also taken some photos at the time but can't find them. ) Carpet was grey colour, and these marks are a darker grey.

I used Prochem Power Burst as a prespary. The carpets were very very dirty. I used Prochem Fibre and Fabric in my extraction machine. No other chemicals were used. On completion I noticed these marks - one was the same shape as the small rug that had been on top of it, and the other an S shape, kind of like my extraction machine hose.

The water out of the tap was pretty hot but not boiling.

At the time I assumed it was that the carpets had been so dirty (ie the same colour as the mark under the rug) that me cleaning them had just emphasised these existing marks. I tried to clean them again at the time but there was no difference.

Any suggestions on how I might resolve this welcome.

Thanks
Andy

How clean is your solution hose?  Could be soil transfer from that especially if the hose is dirty  and becomes coated in power burst seen similar when I do Indian restaurants. I now have designated hose sets that I take to the Indian and fish restaurants I clean.

For the
Did you prespray over the top of your extraction hose? If so this area could have been missed with prespray, and therefore not cleaning as a result. or.....
If you were using hot water the extraction hose (being hot) could have dried the prespray at that point before you could extract it out.
If either of these could be a possibility just prespray and extract again.

Another possibility is a hot solution line could have created a groove in the carpet, the same way an iron flattens  fabric.

As for the area under the table, could this be just a difference in the pile? one area being flattened and the other standing up more. If so just rake over with a grooming brush.
