Review: My goto flux remover - I have been into building/repairing and designing PCBs for hobby and business for 40+ years, and have used many different flux removers. Chemtronics works and drys quickly, that's why I buy it.
Review: Literally makes the board look brand new. Worked beyond all my expectations. - I bought this several months ago, and finally used it on a monitor chassis I was recapping.. It was amazing. Where I had thought maybe I had used too much heat and darkened the board, this stuff shined the board right back up and made it look like new. Functionally, it let me see clearly where I did, or did not possibly have a solder bridge, and gave me confidence in the job I was doing. I just wish it wasn't so expensive, because I'm going to use the heck out of this stuff from now on!!

### ⭐⭐⭐⭐ Worked pretty well
*by L***E on October 11, 2025*

I just replaced all the capacitors from a vintage Reel to Real Player and I must say once I was done the circuit board was pretty mucked up. I use this product and it actually worked pretty good, it's still left a slight film but for the most part it worked quite well. You have to remember this motherboard was from the '60s and it was kicked on pretty good. Glad for the purchase.
