Been trying to get rid a sour smell from AC with no success, have done the following
1) Vacuum interior and clean carpets
2) Change AC cabin filter
I want to get rid of the sour smell and not mask it with a strong car fragrance.
Found several different brands of aerosol AC sanitizers at Autobacs, do they work?
Usage instructions is similar for all brands, leave AC on with fan at full blast and then place aerosol at footwell until entire can is empty.
Thanks.
