This might be a silly question but how do you properly dispose of the soiled cleaning degreaser, and would the same ultrasonic cleaning process work with a second pass of a rust remover?
If you think the product you’re using may be hazardous, it is best to dispose of it at a local hazardous waste collection site. I have never used rust remover in my ultrasonic cleaner, so I can't speak to how it would work in the cleaner and what results you may or may not achieve.
Ha! Wellll...that makes sense! I remember thinking to myself, that is wayyy hotter than 75 degrees F. I wonder why the display would read C when they are selling them in the US?! Rebadged product and too much $$ to convert to F is my guess...
