Hmmmmm, Evapo-Rust.... what the heck is it? Bah, the MSDS is no help! |

--- Quote from: PekkaNF on February 23, 2013, 05:48:32 PM ---Lew, thank you. I was wondering the color...sometimes it's almost like gun bluing - sometimes more like parkerized. Occasionally really nice color and wonder if I could produce it freshly turned/milled parts. --- End quote --- Parkerizing is a process known as heavy phosphate coating (DOD-P-16232 in the formal American military specification which can be accessed through http://quicksearch.dla.mil/). Light phosphate coating (which can be accomplished using Naval Jelly) is codified (here in the U.S.) as FED-STD-TT-C-490 (which is somewhat harder to find as we have privatized nearly all the public specifications here in the U.S.). Does that help? |

Does that help? --- End quote --- Printted the first one. Unusual paper, only 17 pages long...should not take too long to read and digest for further reading. Thank you. That Naval Jelly brought me wrong connotations when I saw it few times....I had nothing to relate into it. But it's more clear now. Clive, that looks to me just like a normal healthy rust on rough castings and I would not be least alarmed about it. Just a little more and that healty rust would push residue sand out of surface and would make castings more machining friendly :wave: Bought small ultrasound cleaner and detergent. Works, but where I have got myself? Detergent selection seems to be very important and my prior experience does not help here at all. I'm really baffled about the results. I have one litre of industrial/professional cleaning detergent that is intended to clean small parts after machining/handling prior to assembly. It works really well, but at abt. 45€+tax/1l botle, it's pretty pricey and reserved only on special ocassions. Dish washer detergent does not work that good, neither straight lamp oil, more to test and google. PekkaNF |

re. simple cleaning: I don't know if you have them where you live but the citrus oil hand cleaners (non-pumice variety) will do a fantastic job of removing grease and dirt, and even cooked-on varnish from metal surfaces. Just spread a small amount on a metal surface without water and wait a bit before scrubbing with non-abrasive a brush and rinsing. And it's kinder to human skin than other industrial quality de-greasers, for obvious reasons, and smells a lot better too. The particular brand I use here in the US is called "Fast Orange" |

I use it clean my hands out of my hobbies :D and my daughter cleans up nail polish and such. Good to keep in mind for future use. I tried one glue/sticker remover that is mainly made out of cirtrus oil and mineral oil and it works pretty good, but leaves lotsa oil behind...needs good hot water wash after that. Hmm. Maybe these citrus things would speed up "pre wash"? Pekka |
