Choosing a contact cleaner which will restore and not harm your equipment is always a better choice than using a low-cost contact cleaner, as replacing your original part once the hidden internal plastics cracked or melted, or the metal shaft seized, are often impossible and tedious at best, so you are better to not attempt to clean with a questionable product and instead live with the unit as it is until you can obtain a suitable contact cleaner which will not harm your precious treasure. You can usually purchase a safe bottle at a decent electronics store or over the internet though it is important to be certain shipping of the product is approved by the shipping service as many contact cleaners are flammable and sometimes cannot be shipped certain methods or to certain locations.
The contact cleaner may air dry in a few hours; no wiping is typically necessary, but. . . avoid spray on things you don’t want affected that should not be sprayed, such as rubberized belts, friction wheels, pulleys, motor shafts, meter displays, light bulbs, audio or video heads, window or dial faces. Good luck cleaning any of those off if they get a mist on them. Be certain to not soak high voltage power switches as they may at some point ignite so please don’t flood your high voltage power switches with contact cleaners, they almost never need to be cleaned and are safer to replace if they would.
