Question about using Ultrasonic Cleaners…

[sna77]

I just bought the Crest 2 Quart (1/2 gallon) Ultrasonic Cleaner, and basket:

Anyhow, after reading a few threads on this, I have a few questions:

- My unit is heated, with a max temp of 80 degrees Celsius. What temperature should I heat the water too?

- How long should I leave the ring in the UC?

- It came with some cleaning solution. A few people recommended Mr. Clean or ammonia. What are other favorite recipes? How much solution are you using?

- Do you dump the water / cleaning solution every time you use the UC, or do you use the same solution for a week or so at a time?

Thanks!

PS: What is the best thing to use to dry the ring with?
