In the garage of the house I inspected yesterday, there was a very powerful odor of chemicals. I couldn't be in there until I opened the doors and aired the place out. Clients were there as well and were concerned.

I suspect the odors were from all the gasoline, fertilizers, etc. The clients didn't ask my opinion while onsite what to do about the odor, but what do /how should I make my comments in the report? Or should I not say anything as the odor will probably go away after the seller moves?
