AC200 from Amerlab is helping me clean the microwave liners with full automation and excellent cleanliness. It can rinse the liners with UPW and dry them with hot air automatically after the acid vapor cleaning process. I was surprised that only 250ml concentrated HNO3 was needed for a full cycle with the satisfying results from the original high ppb level to low ppb even ppt level. Generally, we are very satisfied with the white fellow.
