Some folks use it pure as long as you don't soak/flush too long and make sure you rinse/flush it very well after. If you wanna be on the safe side you can dilute some first and try to see how clean it gets then concentrate it more as you go. Can use some baking soda in water after to neutralize any acid that may have been left behind. If you can add compressed air to your cleaning solution soak it will help even more.

Ok cool. This one says it's 31% in the bottle. We were going to throw it in a cooler but we only have a gallon. Looking at it now we should probably cap this back up and just fill it?
The fact that I'm here helping tells you the knowledge level around at 10:30PM in the Burrard Civic work yard

Ya I've only ever used it just as it comes from the hardware store and flush very well after on things I've cleaned with it. Just use caution with it. Not friendly stuff. You don't wanna breath that stuff in or get it on you. Guess you don't have access to air compressor if you're doing it down on the dock but if you can blow air into it as it's soaking it will clean so much quicker and better than without.

Ok cool thanks. I'll hook it up to the truck exhaust.

Man I don't know if that's a good idea cause that would be adding heat to it and that would cause a lot of hydrochloric acid fumes that could be dangerous.

Sorry and how long should this go for?

Not long or the acid can start negatively attacking metal and solder parts other than the copper parts. That's why it's important to make sure it all gets rinsed really well and/or neutralized with baking soda after using the acid.

If the soak doesn't clean out the holes well enough you may have to drill them or use a rifle cleaning tool to scrub out the holes more.

I would just take it to a rad shop and have it tanked. Not expensive and they can pressure test it afterwards

Pull the end caps and use a straightened coat hanger to clean the tubes, get some neoprene gasket material and make new gaskets. I've found lots of crap hung up inside mine that an acid wash won't touch. I've also had problems with corrosion on the inside of the caps. I use 1/4" SS plate and make new caps.
