I cleaned a stainless steel container and lid to clean parts with acetone. I rinsed and brushed the inside and outside with 1:30 Simple Green:DI Water, washed the outside with DI water, sonicated for 10 minutes with this solution inside the container, washed the inside with water, sonicated for 10 minutes with DI water, washed out the inside with acetone, and sonicated with acetone for 10 minutes. I then labeled the container and lid.
