But DO NOT wad up the linseed oil-soaked cloth and toss it aside. Spread it
out, outside, so that it will dry completly. This will prevent spontanious
combustion that linseed oil soaked rags are known for.

We had a lawyer burn his house and family down with oil soaked rags
left over from a refinishing job around here a few years back.

Take oil soaked rags, linseed, tung oil, watco , wood stain etc
outside and burn them. They only burn once.
