Try this brilliant spray foam tube cleaning trick
We all do it, so don’t feel bad. You forget to clean the plastic tube and nozzle after using half a can of spray foam. Do you go to the store a month later when you need more foam? Nope! Just push a 12-gauge wire into the tube and shove out the dried foam in a single piece, then clean out the clogged nozzle with a toothpick or small finish nail. Now go ahead and use the leftover foam. Thanks to Michael Mata for this ingenious tip.
