Cleaning contacts

[Chris Fulmer]

What methods does everyone use to clean connectors and contacts on semi old electronics? I have spray cleaner for electronics by CRC but I think it is corrosion not chemical.   Mechanically with a brass brush or something is probably great for the external parts but not inside connectors.  I also plan on using some Dielectric goo when I put it back together to prevent this in the future, unless there is a good reason not to.

I have had great luck with a product called deoxit.
https://caig.com/deoxit-d-series/ it is very expensive. If I remember
something like $15 for a very small spray can. I once used it on the
turn signal switch on a 1971 Datsun 510 I sprayed it into the switch
and flipped left to right several times fast and sprayed again and
turn signals started working. I have used this stuff many times. I
would buy it again.

There is another product that I have not used yet but have herd good
things with electrical stuff usually automotive.

I have a bottle of it but have yet to use it on anything. Amazon has it.

Both of these have protecting properties.

Thank you Avery.  I went with the deoxit because I have found there clock lube to be really good.  I did not end up getting the same type as you mentioned.  I did not realize how many products they sell. I got one that was available on amazon, and said it removed oxidation and protected.  My extruder stopped skipping steps, so now to chase other problems out as they show up.
