I check if for leaks in pure water in 25 bara pressure :D.

so does the vinegar remove the oxidation or does it just polish the copper?

I thought wire brush and sandpaper was a no-no. :confused:

Idk. If you sand down too much you could open a pinhole in your braze?

Copper dust gets inside system?

Naturally, you "could" sand that deep...but the chances that you will breach are very slim. For example, lapping is just fine since the bottom of your evap should be a very thick chuck of copper anyway for good heat transfer.

Exactly, that'd be a hell of a lot of work ;) And get you nothing, I like the vinegar idea though, as long as it doesn't cause oxidation afterwards. And it does seem to create a really nice clean, or do you end up really sanding and lapping away after pio

YEs vinegar sounds like a very good idea, but does the copper need to be soaked in vinegar for like hours? or can I just pour it over tubes and it immediately breaks up oxidation?

i would imagine that a overnight soak would be required as vinegar although acidic is not that strong

So then piotres, how do you soak your last joint?

Do you have a wierd shaped bowl that you tip the unit into when you want to clean up the last braze?

Or do you just sandpaper it like nol?

he said in one of his threads he sands his joints and cleans them with a wax that he uses to clean his car.

- Vinegar is acid
- Acid gets rid of oxidation
- Acid on inside ruins compressor

You must let it sit for like a day.
