I think the flakes might be "SALTS" precipitation, Filter them out with a coffee filter- one possible "solution" (Pun intended!)Jackpot! I think you are correct.
I need to purchase some Ph testing strips to keep tabs on my concentration levels and "sweeten" the solution periodically to maintain effectiveness.

I know he mentioned that using HARD water instead of distilled water can cause surface finish streaking, & maintaining your ph range is critical to the solutions effectiveness.
Hood hinges and latch catch are manganese phosphate. Bigger darker almost black crystals, must be oiled and is used for applications where parts rub one another.
The black Zinc on bolts is a passivation conversion from silver zinc using a chemical dip.
Same with Yellow, Clear, and Olive. ALL four are Passivation conversions of silver zinc which modify the surface of the ZINC coating into a harder surface more resistant to abrasion and corrosion.
FWIW I have been ZINC plating parts lately and as a sample I have had a fender shim laying in the driveway since January and it has yet to show a spec of rust yet.
Are you guys using it mostly on bolts? or what other items are you using it on?The big parts on our cars are the hood hinges-springs and the hood release mechanism in front of the rad support.
What is the process for using it on bolts that is the most simple?
