Solvent for cleaning Teflon coated metal molds

We specialise in Teflon coating of metal molds used in molding of rubber and polyurethane products. After some time with continued use a black deposit is formed on the coated mold which is cured rubber . The problem is we cannot use abrasive means to clean these deposits as it will damage the Teflon coating. Can anyone suggest a solvent which readily dissolves these deposits from the coated molds.

Similarly in the case of molds producing PU foam parts a deposit of the release material and PU residue is formed which needs solvent cleaning. Can anyone help?

Being that teflon is almost chemically inert you can use this in your favor. Just about any solvent is not going to do any harm to the teflon, but it should be able to clean off just about any residue that you have on your parts.
