Not affiliated in anyway,but my local electronics shop recommended it.

Between lightly dremel polishing high amp factory brass connections and spraying this stuff on interior high amp connectors, i went from 13.7 to 14.5 volts with my 66 big cars engine running.

Can't hurt to clean connections very 50 years or so...

YMMV

Thanks for posting, I'll have to look into that stuff.

 

Second to none in the world of contact cleaners.

Been using Deoxit for years.

 

I bought a couple of cans after your post and forgot to reply.

Thanks for the tip. It works great!!

 

I bought some contact cleaner at Radio Shack, ( most are closed) probably the same stuff.

 

I've used this stuff at work before (repairing electronics for the FAA). I wish it wasn't so expensive.
