Question How to clean dash harness fuxe block terminals

My dash harness wiring is in good enough shape that I am not going to replace it while it is out but looks like the terminals that hold fuses and spade terminal ends could use a cleaning.

What is the best way to clean them? Is there a solution I shoud use or just a small wire brush?

You could probably use a can of electrical contact cleaner.

Blue Shower is an electronic tech spray. It works good, doesn't damage plastics or wiring, evaporates quickly, and probaby kills the ozone. (JK - they changed the formula). Or you can use the old school q-tips and alcohol method. An ignition or hobby file [1/4" wide blade] is good for cleaning up copper/brass contacts. Clear silicon ignition grease (dielectric lube) is good to smear into connections to prevent re-corrosion after you've cleaned it, if you live in a corrosive or damp climate.

Use a brass "Marine tooth brush" to remove tarnish/corrosion. clean with isopropyl in a spray bottle and acid brush, then dry with compressed air or just air dry. Using any type of corrosive cleaner may deteriorate the wire over time. Treat the cleaned contacts with a corrosion inhibitor, wd-40 and dry again w/air.

If just dirty, use a q-tip with wd40 or any other mild cleaning agent. If you see rust, better to leave alone as any abrasive cleaner(wire brush, file, penknife etc.) that will clean rust will also remove the coating on the connectors that hold the fuse's. I have that problem on one of mine and it looks kaka.
In reality you can't easily get to the inner part of the fuse holders to clean them with any tool I've ever seen. I used Qtips to remove any loose crap and then some dielectric grease to minimize the effects of condensation and the water leaking design the trucks came with from GM!!
