I bought this primarily for cleaning car parts as I had some projects coming up. I rebuild the TBI on my Blazer and it did a great job cleaning off the dirt and grime that had accumulated on the parts.-It is pretty loud and was annoying to me, so I put it in the back yard to clean the parts while I worked in the Garage.-Be sure to rotate the parts around a little and you may need to do multiple 30 minute cycles to get the more dirty parts clean.-The only things it had issues cleaning was the really thick oily, dirty crap that was down in the tubes of some of the parts, but for the most part I was really impressed with how it cleaned.-Don't leave your parts sitting in it overnight with it turned off. That probably makes sense to most of you, but I did it and some of my parts seemed to have a weird corrosion type thing on them. Totally my fault for leaving them in there tho.Overall I really like the cleaner and think it works exactly as advertised.
