Hi Guys any help with this please........Did a large modern church hall 16x16 metres about 2 weeks ago,was polyprop commercial low profile carpet,cleaned up well and got loads of dirt and grit out of the carpet.Cleaned HWE
Customer says that theres a lingering smell still around od cats or dogs,and I'm still awaiting payment.
No ventilation was used after the cleaning as they locked up the room.
Any ideas of what it is and how to solve it
Thanks
Wayne
