i have a bad smell coming from the air con
will this get rid of the smell
Yes. The previous owner of my car was a smoker and the product neutralised the odours emitted from the air con, together with the odours which appeared to be embedded in the carpet and upholstery. I would imagine it has a similar action to dry cleaning, which is also solvent based.
After the initial solvent blast, the interior and air con is left with a fresh/neutral smell.
