A word of warning about "Goof-Off". It is a paint remover. If left too long on a painted sueface, like a minute, it will remove the paint. Don't spill any, splash any or leave a Goof-Off soaked damp cloth on a painted surface. Careful usage in the kitchen can remove really stuck on food stains and dirty finger prints. Goof-Off may contain acetone, which also works well. Another good product is Krud-Kutter available at Home depot. The odor of Simple Green Makes me sick, so I don't use it, others do.
