Refers to where you have to again apply (because the previous layer of said cleaner that you'd already spread on the joint accidentally got wiped off or contaminated) ferrous-metal-cleaning paste/fluid before using solid/acid-core solder to join non-electronic-type items, such as sheet-steel or piping.
Soldering is often cranky and tedious enough as it is, and so having to keep applying tinner's fluid is enough to give you acid-reflux from sheer frustration!

Acid salting is when you add HCl gas to an Amine to turn the freebase Amine dissolved in dry ethanol into an HCl salt. An example is bubbling HCl gas to turn freebase Propylhexedrine dissolved in ethanol into Propylhexedrine HCl. It also works with Amphetamine (A), Methamphetamine (MA), Ethylamphetamine (EA), MDA, MDMA, MDEA, Mephentermine, Modafinil, Propranolol, and more. Adding HCl acid solution works too, but it's more difficult to get powder and crystals.

acid is not only the name of a drug or fiery substance, it can also be a name of a person. people named acid can be the baddest bitch you know, the most dap dapper of the dapper gentleman, or the most strangely attractive old hobo man with an equally strange essence to match. people named acid are most commonly all of the above. they are people of strength, kindness, superior humor, and are very chill and non judgmental (which makes them good listeners). they can’t always relate but they won’t ever make you feel less than valid. they know trauma, but, if you are friends with someone named acid, let them deal with it, they have a method and they’re gonna do it their way. they are generally one of the best friends you could have in your life so you better treat them correctly and don’t let them push you away (which they commonly tend to do as a self sabotage mechanism). you gotta keep their tiny, gremlin ass right next to you and hand them some nic, chai tea, and some popcorn goddamnit. they won’t leave your side. give acid some love, you won’t regret it.
