A bit Pricey but works great and NO discoloring on aluminum
Ok, maybe I'm too fussy, but when I put my 30 year old aluminum carburetor in the ultrasonic cleaner bath, I want it to come out bright, looking like aluminum, not like some dingy dirty color. As an ultrasonic newbie, I watched several YouTube reviews of cleaning solutions and tried some that were suggested as being cheap and not discoloring aluminum... Well, in my first try with a low-priced citrus based cleaning solution I turned the top of my carburetor from a dirty but bright object into a battleship grey ugly thing. So I went back to look online and found someone using this Ultrasonic Carburetor Cleaner product on their old carb and it turned out nice and bright. So I gave in and bought a gallon of this product. WOW it really worked!! The next parts I tried using this product all came out clean and bright! In the attached pics, the first pic shows the grey top of the carb and the second pic is the bright bottom of the carb. Unfortunately I tried the top first with the el cheapo citrus cleaner. Both cleaners worked but only one left the surface unchanged. This is a very good product. Read more
