I've only cooked them for 30-45 minutes and haven't had that problem.

Purple Power has turned some cylinders a little gray.

Media blasting works excellent for restoration work.

I use dawn original... The blue chit

They were hot for about an hour. The machined factory bases have discoloration in spots. I didn't boil them. So they reached maybe 190*F. Glad they were my jugs and not a customers.
The pod discolored the intake and transfer ports the worst. Theses jugs were shiny except the oil stains that it left behind around the exhaust port, again. It will take bead blasting or something to get them shiny now. These pod things are waaaaaaay more harsh than spray nine, simple green or awesome. It looks liked they soaked in purple power. I hate that chit cause it discolors all pot metals.

I used these. I boiled the one I posted earlier for 3-4 hours. No dark gray.

I'm just lucky boss

Let me grab a pic. It was some reaction. Maybe the plastic bag caused it. Damn thing leaked anyway after the first run of just water. My one gallon of clean water had one pod in it.
Brb

My camera just won't focus in today. The transfer ports were silver now they are near black. Outside was white and now it's charcoal grey. Notice my fill line across the spark plug hole. Note the original color on the base of the one. jug.

Can see it a little bit. LA Totally Awesome Orange will turn a bright shiny KS cylinder dark gray like a 362 or 462 cylinder in 2 minutes lol

It took the combustion chamber carbon out of one jug and polished the band. It had very soft carbon in it. Why I have corrosion, idk.
Maybe the metal studs touched of a galvonic reaction?
Never using that pod again on bright aluminum.

You could try some aluminum wheel brightener or vinegar on them, it might brighten them up.

These might be a bit better. The few bright spots left. Those transfer ports were silver and clean.

Everthing is going whack now trying to upload pics.


I'm done.
Got heartburn and I'm in a bad *f-wording mood.

I've never had anything like that happen, even with Purple Power.

I got Whitehouse white vinegar here. Drop in a chainsaw bar with rust and you don't need a battery.

We used to get a purple cleaner around 1990 that would do just this. Turn stuff like cast aluminium dark grey in minutes. It would bubble on a hot intake manifold. You smell the fumes. I etched plenty of non ferrous metals with it. Water neutralized it just like metal metal conditioner for removing rust on steel. After washing the metal a lot of times we just shot some clear on it. It turned cast iron damn near black in minutes. Same thing going on here but at a much slower rate.

The good news is I like the color on certain things.

Got about ten minutes left here to dab on some vinegar for a test.
I learned something.

I just took a closer look at that 670 cylinder and inside the transfers where I didn't scrub it down afterwards has turned dark and powdery but comes off with my finger. I'll have to get a brush in there before I use it.
