wanting to clean all my eletrical connections, what connections are a must to clean and what do i use to clean them with?

 

clean with brake and electrical cleaner then use dielectric grease...

 

Just watch out ...........Some Brake cleaners are no good for the Electrical plastic connectors........They may cause a reaction on contact and heat up the plactic.......

I would only use the electrical cleaner that's safe on all plastics........Then like said above.......Dielectric grease.......

Note as a electrican by trade......These cleaner are very high flame point, and please give lots of time to dry and evaporate before sending and current or power through them.........Most of these cleaner will catch fire,if a spark is present.......Caper.........

 

make sure the grounds are good as well.
