I'm not an acetone fan except for very limited use wiping things off. It's pretty harsh (mainly on the user). Kerosine is an amazing solvent. As an added benefit, it doesn't dry out the pores of the metal like acetone does. If you use something like acetone or brake cleaner, you have to immediately follow up with a coating of petroleum based lubricant to get into the pores of the metal. Failure to do so can result in flash rust.
