Which Caig?

I think ProGold is their 'sealant' formula that protects for a few years (unless you're unplugging and replugging a lot) which is very conductive and remains so...can be used on any metallurgy. I use that and Deoxit D5 first to clean. The D5 is the best cleaner I've ever tried. Their both-in-one cleaner/sealant formulas don't seem to clean nearly as well. A little #0000 steel wool on contact surfaces first can work well, too...a bit of a pain, but it does seem to help with the sound a bit sometimes.

Thanks again folks. I am ordering the CAIG Audio Survival kit. Looks like it comes with the required tools.

That's a good choice, I have the Survival Kit as well. But you'll still want the large squeeze bottle, as the amount of DeOxit supplied in the kit is only a small tube and a small aerosol that tends to over-spray.

Thanks Dgarretson. I will order the bigger bottle as and when needed. This would be my first time trying to clean the terminals.
