I have been having problems getting a uniform anodizing surface. The parts that im doing will have runs where the dye wont take because it has not been anodized. I believe it is due to cleaning. I heat my cleaner up to 140F and dunk in for 10 min. The water test never passes!
I normally take a toothbrush and scrub. I did this one part a 2 times the first time without th toothbrush cleaning and the latter with the brush. It made a major improvement but still not a uniform anodize grrrr!!!
(especially around holes)
I do use RO water, I do spray extensivly.
Im wondering if there is anything that can clean my parts appart from the degreaser?
