Dirty switches are the obvious first thing to check. Servisol 10 will work better than plain IPA (don't use WD40).

Dissolved belts can be a pain to clean off, and the chemical composition varies. White spirit / turps substitute is probably as good a solvent as anything. Ordinary WD40 is mostly white spirit so can be used as a solvent, but apply it using a rag rather than spraying directly, and take care to clean off all residue or the new belts will slip. Acetone tends to attack plastics, so if you decide to try it from desperation try it on a bit of sacrificial plastic first. IPA is safe but doesn't tend to be much use shifting these hydrocarbon deposits.
