Let's start over......
TB cleaner.
The gunk in a TB is mostly blow by oil that has hardened and penetrated the metal surface. The gunk in a carb is gasoline deposits, blow by gasses, oil and is generally baked on at higher temps because it is closer to the cylinder heads. So naturally the Carb cleaner would need to be much more harsh of a solvent to do its job efficiently.
Dont risk your electronics by using chemicals that are designed to use something else. I bet you dont use steel wool on your mother's fine china right?
