Ultimate way to clean your toys? I'm thinking it'd be a great radiator flush, no?
I have no experience in using such a mix for cleaning loops, but I believe it would make quite a tasty mix for something to do with fish.
Salmon perhaps? :D

3 cups distilled white vinegarQuote:

It's a really nice acidic mix to clean copper, (once mixed) but dont leave it any more than 30 minutes :up:
I'm not sure about the radiator but its nice for cleaning corrosion of the block.
Rather pure citric acid.Juice is such a recession:D
Ive used this to clean copper..minus the lemon juice..make sure you rinse it VERY well when done. It does a great job cleaning copper tho.Quote:

This will clean the entire loop too. Just rinse with distilled water.

Chemistry lesson...
Distilled white Vinegar pH level: ~2.4
Lemon juice pH level: ~ 2.2
I'll leave the rest of you to figure out what I'm getting at. ;)
Lemon juice wins! (coz it smells fresher) :rofl:Quote:

Guess you missed the point I was making. Both vinegar and lemon juice are in the same acidic range, that makes one of them (the vinegar) redundant. Just use the lemon juice and salt, then use a good base (like baking soda) mixed with water to rinse the parts with. This will stop the acidic reaction and keep your parts from looking funny after the final water only rinse and they've dried out.Quote:

Pull apart and get the big stuff (if any)
Rinse + old toothbrush (distilled water only)
Clean in solution (Lemon juice + salt)
Rinse in base solution

Dry
Re-assemble
Steps 3 & 4 should only be done if it's absolutely needed.
Please remember that acids eat things...especially copper. If you see your mix turn bluish, that's dissolved copper and you should cease cleaning immediately and start the base rinse.
My experience:
I have a 2.5 gallon commercial ultrasonic cleaner. Worked in aerospace for a number of years primarily doing O&M work. We had some solid copper machined diplexers returned from the field with severe corrosion on the inside. They were pressurized with SF6 gas. The corrosion was green, about an eighth of an in thick. I didn't know what to clean these with so I tried adding about 3 cups of white vinegar to the water. It removed all the green corrosion very quickly, however, it left the copper with a very, very dark discoloration.
In the end result, when the corrosion was removed there was quite a lot of pitting on the inside. They would never stabilize again and were discarded.
I suspect a similar reaction would take place on any copper this type of mixture was used on. Now the discoloration was just on the surface of the copper, very thin, almost like a plating.
Just an fyi.
Nobody particularly liked my earlier suggestion of sulphuric acid, so now I offer up safety pickle it's a pH neutral oxide remover for gold, silver, brass, bronze, and... copper. Again, give your nearest jeweller a call and he/she can probably let you have a little baggie for a few quid.
Anything using SF6 is subject to arcing and gas breakdown, the left over metal fluorides were probably responsible for the dark discoloration, not the cleaning solution.Quote:

The cleaning solution caused the discoloration on both the inside AND outside. Prior to the cleaning the outside had been bright & shiny.Quote:

Regardless, it doesn't etch copper like say nitric acid, though it does leach copper oxide and a bit of copper along with, it doesn't make any noticeable mark or impression on copper (or silver, or gold) and that's 7h at 40C and over night at ambient room temperature (probably about 10C) so it's certainly safe to use, just make sure to neutralise thoroughly before putting anything back in your loop.Quote:
