DeOxit and ProGold

I like ProGold but never spray it onto (or into) anything.

Instead, I spray a tiny bit on a Q-Tip stripped of most of it's cotton tip and clean the connector carefully by hand. Wipe off all excess so the surface hardly shows the application of the product.

I only use DeOxit on badly corroded things.

RCA, XLR speaker connections and such get only the ProGold. DeOxit sounds really bad unless it's completely removed and then replaced with ProGold after the initial cleaning.

ProGold is also sold in a small plastic pancake with screw off lid. Inside are small saturated cotton squares handy to pick up, scrub with and dispose of.

I like the sound of ProGold as much as any product out there and I've tried at least a half dozen over the years.

Great stuff, but DON'T SPRAY IT. Use brushes, q-tips, etc to apply it just where you want it. It does NOT evaporate and you don't want to get it all over everything ;--)

ProGold is a great product, I like the whipe too, easy to use and no mess. I believe the ProGold name has been changed to DeoxitGold.

I tried a new (to me) tweak this weekend, by cutting Q-tips in half then sticking the stick part into my dremel tool, then applying either Deoxit (for cleaning), or ProGold (for clean up and conditioning), directly to the Q-tips, I was able to easily clean PC plug blades and speaker cable spades. Worked really well getting some old QuickSilver Gold off the spade connectors. You will go through a lot of Q-tips to do a really good job on dirty stuff, but the Q-tips are soft and you shouldn't hurt the finish of whatever you are cleaning if you go at low spead and do not press too hard. You can use dry Q-tips to clean off the Deoxit residue and when finished you can still apply a thin layer of Pro Gold using the applicator brush.
