Has anyone found the best way to clean coins?

Are you cleaning silver or copper? If you are trying to get a date then the coin probably isn't very valuable, so on silver water and baking soda mixed into a thick paste works well and on copper Novus 2 fine scratch remover works well.

I am guessing you are not asking about clad? If you are, the just
small pebbles u use for the fish bowl, salt and vinegar. If your speaking
of "old" hjistorical coins then I can't say.

On super old possible key date coins, you do NOT want to tumble or even try to clean them..!..maybe a rinse and soak in water so you can see the date...
For the rest and clad, like Robert said, tumble away with water and a mild detergent to knock the stink off...some will never come back to any appreciable lustre that can be spent, so those ones go through the coinstar, or are used in vending machines, toll booths and the like...this modern clad is no good for holding street value for very long...it rots pretty fast...you can also make yourself an electrolysis rig out of an old cell phone charger to bring some of your common silver coins/jewelry back to nearly full shine if you want, or do what Happycamper said,...plenty of youtube vids out there on how to do it...

I think you should specify what kind of coins. There are different methods according to the coins of copper, silver, modern alloys, old or new, underground or underwater.
Every problem has a solution.
If an old coin with alleged historical or numismatic value, NOT CLEAN. Do NOT RUB. A bath of one or two days in distilled water and a little toothbrush. What is gone, no returns.
On other types of coins and cleaning I can not advise anything for sure. € euros coins are cleaned well with etching, aqueous solution of hydrochloric acid, with appropriate security measures and separating the coins values. But I don't know of american coins, sorry.
The sea salt crust and sand is removed some coins with a vinegar bath.
If a silver coin has small black spots can be removed by rubbing with: pencil eraser (soft), cigarette ash, with a paste of baking soda and water.
Testing in some valuable coins.
If something goes wrong, I have not been, I do not know, I was not there.

For recent coins, wanting to put them back into circulation, either use them in vending machines, or try pickling.
My neighbor steelworking company pickled some badly tarnished Euro coins and they came out in mint condition.
What usually takes me days and frustration, took them a few seconds.

I use a ultrasonic jewelry cleaner to get the dirt off so I don't damage a nice coin.
For clad coins just to get the stink off I use a dual barrel tumbler from Harbor Freight. Separate penny's from other clad. Tumble with aquarium rock, just a tad of dish soap.
If they are really crusty use aquarium gravel, water, salt and vinegar solution. Rinse in soap and water and they will be perfect to roll and take to your bank.
I only use coin star fro crusty penny's bad zincolns with chunks out of them.
