Never clean a coin, unless you find it metal detecting. It will ruin the value.
However, if you find a coin while metal detecting, then it will probably have some dirt on it. Try rinsing the coin in water, and then pat dry with a towel. If that doesn't do it, try soaking the coin in acetone and then rinse the coin in water.

Silver coins come out of the ground in nearly the same condition as when they were dropped. Other than a pure acetone soak, do nothing put a pure water rinse and air dry.
Copper can frequently become corroded in ground. But still use nothing but pure water and pure acetone.
Never scrub a coin of any type.

ok I see some videos of them rubbing the coin with dirt on it and all I think of is like 60 grit sand paper against it lol. Thought I seen someone using peroxide on a coin or might have been a button. I'll have to get a hand held spray bottle for them.

There are a couple of other non-damaging ways to remove soil and perhaps some of the corrosion. One is ultrasonic cleaning - you'll need an ultrasonic bath and some detergent in water. Many ultrasonic baths are available, designed for jewelry.
Another somewhat harsher method often used on coins found by metal detector is to tumble in a rotary rock tumbler with a polishing medium. This will remove corrosion and is good for crude overall cleaning, but can be abrasive and generally should not be used on coins with nice surfaces or significant numismatic value. There are many articles on the pros and cons of this method. Good luck to you!

If its spendable, then rub it with toothpaste and water. If its a rare coin, be very gentle with removing the dirt as you can make it worse.

Metal detecting recoveries? Good old soap 'n running water, and rub with bare fingers.
Coins that are still unidentifiable may need brushing.
Worn bronze coins that are so heavily patinated to black or very dark brown may not be worth much. Such a heavy patina can completely ruin eye appeal, and make them difficult to photograph. If all of the detail is obvious and easily seen, then best left well alone, without brushing. Leave them very dark.
