ELI5 Money laundering. I've seen all the tv shows and I still don't fully understand how you "clean" it.

You need a legit business that deals in cash, say a car wash.

Then, let's say you cook the best meth in all of New Mexico and you need to be able to use the money you make selling it to pay for legitimate stuff, like cancer treatments. 

Now, you'll slowly bring some of the cash you made selling your meth to the car wash and give it to your accountant wife, who is in on the game.

She will create receipts for things that never happened and attach them to the illegally gained cash. She'll probably tell you to dump out some car carpet shampoo and such to support the fake receipt.

Now, just bring all that cash to the bank and deposit it into the car wash's account.

You'll probably run into a problem with having to launder too much money to stand an audit. So you probably should have set up a chicken fast food restaurant with a lot of locations.
