I had about 3/4 of a gallon of linseed oil in a metal can sitting on the floor of the shop in a corner. The bottom rusted out and it slowly weeped out. I pried the empty can up and there is a patch about one foot square with what looks like about 1/8" thick varnish. It is fairly hard like epoxy. I will chisel it up and then maybe paint thinner/acetone or what?
I had been smelling the linseed in the shop air for months but I like the smell so I was not concerned. I poured silicone sealer on the concrete shop floor when we moved in about 15 years ago so there may be a chance of getting it so it is not sticky. I plan to move my belt/disk sander to that area so it should be covered.
