Ultrasonic chain cleaners

I bought one of these and it works quite well.  https://www.amazon.com/gp/product/B07HRFDXS8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1


I fill it with hot water (60 deg C) and use Simple Green HD concentrate in a freezer bag with the chain.  It typically takes several cycles.

This is NOT the answer to your question, but I have recently converted to full-immersion waxing and would never go back.  Now the only time I clean a chain is when it is factory fresh.

Wax on my gravel bike has been fantastic.  It is SO quiet and it's super nice to handle a chain with bare hands and not worry about nasty stuff on my hands.

1. Never put anything directly on the bottom of the tank! Always use a basket or suspend the item to be cleaned off the bottom in some manner.
2. Always fill the tank to the fill line! I think Josh indicated that isn't necessary, but I trust the instructions of people who make the product. They all say that not filling the tank can cause damage.
3. Never use flammable solvents in the tank! That could cause a fire.

holy cow who leaves a chain in anything for 5 months?

<---this guy.  I left one in the bottom of my wax crock pot during knee surgery recovery and it came out all rusty.
