Commercial cleaners for dug coins?

[Juice in the hole]

I've tried numerous methods with only limited success. Hot peroxide dips, olive oil soak, dry picking, Arm & Hammer Super Detergent dip, naval jelly and lemon juice & baking soda. They all kind of work, but some are more destructive than others. Is it possible that a commercial coin cleaner can safely clean copper and silver coins without destroying them?

I've scoured the net and found a couple: https://www.hobbysupplydirect.com/Betterbilt-8oz-MS-70-Coin-Cleaner-p/51610.htm?dfw_tracker=2226-37760&gclid=CPmwg_vr6L0CFWXl7Aod0DcAFw

Mint State All Natural Copper Bronze Cleaner Coins | eBay

Any feedback on either of these?

Worth a try on non-key coins.
