I'm throwing out a lot of old packaging materials and was advised by online AI that gasoline and/or acetone was a great solvent for urethane foam!

I happened to have old gasoline I needed to dispose of on-hand, so it was serendipitous.

I tore up the foam, put it in a large cement mixing bin, and poured the old gas over it. My plan was to melt the urethane down into sludge, let the old gasoline evaporate, and then have far less volume to get rid of.

Well, it doesn't work. You end up with gasoline soaked sponges.

Protip: always test with a small amount first. Of course, I did not do this.

I was not making napalm. I'm just trying to dispose of excessive quantities of urethane foam without it taking forever because of the ridiculous volume to weight ratio.

I can tell you from my childhood that styrofoam + gasoline gives you jellied gasoline, which is similar to napalm. That's what I was hoping would happen with urethane foam. Then I could evaporate off the gas and throw away the leftover plastic sludge. They lied, it doesn't.
