Im just sitting looking at IICRC odour control courses because odour problems seem to cause me the most problems and stress.
And right on cue the phone rings from a job i did the other day - smell still there after cleaning.
She says the odour is from where the dog ate a pack of butter on the landing
I think he had some meat as well.
Polyprop felt back cleaned with f90 with bactericidal deodoriser in the tank and whole carpet treated with deodoriser after cleaning.
Any ideas how to proceed??
