Review: Magic in a bottle - Move over IPA! - This works flawlessly. Easy to apply, and eats through even the toughest of flux residue. I recently tried out some new solder on a test board, and this solder had some god awful quality “rosin” core. My usual 99% IPA wasn’t anywhere near strong enough to shift it. If anything, all it did was smear it in, and make an even bigger mess of the board, leaving a very sticky, grimey residue. This stuff however, cleans off the flux like it wasn’t even there in the first place. I will note, there is probably a technique to how you use this. I personally used an ESD brush, and painted it on to the PCB over the kitchen sink. I then thought it would be wise to rinse it off with some IPA. (Remember what I said about the IPA earlier?) well, the flux re-accumulated on the board, and in the kitchen sink. Leaving that horrible residue everywhere! So for my next round, I reapplied the flux remover (with the same brush) and dabbed it dry with a paper towel. This time, no mess, and I was pleasantly surprised to see a nice clean PCB afterwards. This stuff does have a little bit of a scent to it, but it’s nowhere near as pungent as my 99% IPA is. Given that most of my soldering supplies are from desertcart (flux and solder) you can’t always garuntee that they will clean off the way they say they will. In fact, most of the stuff I purchased said IPA would do the job; it didn’t. But I am certain this stuff will take care of it all! Well worth the money. And should I run out, I’d get more in a heartbeat!

Great - does what it says on the bottle

### ⭐⭐⭐⭐⭐ Go Pro 👍
*by C***Y on 28 March 2025*

So much better than standard Isopropyl Alcohol at any strength. I have been using 99% IPA for years with my soldering, but decided I wanted to in the words of Inglorious Bastards - Go Pro. And this stuff has upped my game. IPA while doing a great clean up, cannot quite get that last bit of residue left behind. I thought it did until I started using this. Then you realise this gets you PCB spotless. Worth every penny, and will last for ages.
