I use DeoxIT D5 in the aerosol can.

Once I finished rebuilding a 41-226 "Sled," I tried using contact cleaner on the pushbutton mechanism. The pushbuttons still refused to work correctly after cleaning with the generic contact cleaner. So, I sprayed them with DeoxIT D5, and that's all it took...the DeoxIT restored the pushbutton mechanism to proper operation.

I'll point out that you need to be sure that all of the DeOxit is dry before you apply power.

Yup. Allow the DeoxIT to evaporate before applying power = let it dry before applying power = same thing.
