Default White spotty haze after sealing and dry

As long as the parts are wet they look prestine... but after they dry... there is this white spotty haze or film (neither word is a good description.. it's more of a haze with white spots in it). Searching around I found maybe a possibility that I need to increase the Current Density? I was thinking that it was some particulate matter in the dye... but I have not experimented with drying the parts before sealing to see if it shows up at that stage yet. Sealing process is through the boiling water method. To remedy this for now we have been applying a very mild aluminum polish (used on automotive wheels) and it seems to work... or maybe it is just covering the spots up. I don't know but they look very nice afterward. But on the brushed finish parts, our client is not satisfied with some parts as we think the polish might be building up in the brushed grooves and causeing more of a buffed look than desired.

Has anyone else run into this haze that might point me in the right direction??
