So we noticed a gas-like smell in our basement in February. The smell seemed to be getting stronger. I thought of getting a gas detector. We traced the smell to the room where our used paints are stored. At the beginning of March husband M figured it out . It was a leaking can of Varsol (mineral spirits) that had bled into the cardboard box that the plastic can was stored in. Varsol is highly flammable so the smell was worrying. We put the can and the cardboard in our side yard overnight and fortunately the hazardous waste disposal place was open the next day and husband M was able to dispose of it. The attendant said they didn't really take soiled cardboard but he decided to put it in their garbage. It was a relief to have this problem solved.
Now on to April!
