why is welding stainless dangerous? I do that from time to time too.
I am a welder by trade actually got sent to this site from miller welding forums,
Stainless Steel, Chrome Molly, and a few select other metals put off Chromium Hexavalents which are very very bad for your skin and lungs we are required by osha to either wear a respirator or positive pressure ventilation system while welding such materials. the amount you can breath as far as osha's regs are less than 5 parts per million with out needing a respirator and as most of you can guess it goes that high pretty much as soon as you strike the arc i could only imagine what electralysis would put off
wow, me and a buddy tried this method and it works great.
first tested on generator bracket then a water pump from a flathead.
amazing. i can save $$ from the beadblaster now.
thanks for the chemistry lesson.

The same runoff from soda blasting and home clothes washing machines is not considered hazardous here, however, it would depend on what you were removing. Personally, I skim the crud and filter the remainder before disposal so there's no question about the grease and paint. Sodium carbonate and rust in water is not considered hazardous in my area at least. Straight down the drain is allowed. Check your local laws.

Check this out. I make setup using scrap steel tubing held to the side of a 5 gallon bucket with jumper cables my test went really good and I realized I needed to leave it longer. But I broke it down and came back to it the next day. Being that I've been burning the candle at both ends trying to get my car running I was tired and distracted. Here's the good part. I hooked up the cables backwards! The carnage was impressive. These valve covers were already written off because of the rust. My problem was with all the red-black going on. I just didn't pay attention. Lesson learned.

Honor!
Honor is something you EARN and then maintain!
It is not something that comes to you through deceit or by sleight of hand, or by the slathering of Bondo!
It's good to know this stuff.
I for one am glad you let us know about a ahh crap.
And showed us the result.
Then someday I wont make the same mistake.
Thanks
Fortunately, it was a cheap lesson for you. I learned that one many years ago removing light surface rust on a finished pair of ported 440 6-pack heads that were poorly stored. The one head didn't pit as bad as your photo - but bad enough. Well, it became an excuse to get the Stage IV heads. I almost worked a trade of the fresh 440 long block and a complete 428CJ for a compete '71 Hemi, but that fell through at the last minute. So, it remains a bad memory... lol.
