Chemtronics Flux-Off 1035 Concentrate Flux Remover Aerosol Can - Flammable - ES835B [PRICE is per CAN] by Chemtronics Flux Off Rosin

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.

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!!

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.

This is my third order of Chemtronics cleaner, it works great for cleaning off flux and it does not damage the shiny finish of the board like alcohol does. When I give back the repaired board to the owner he cannot tell were I worked on it and that alone was what got me hooked on this product. With alcohol you could always see a dull looking area on the PCB were the alcohol destroyed the clear coating on the board.

Love this stuff. It cleans well and the brush makes it super quick and convenient. Way better than spraying then using a different brush.

When it comes to removing flux from a PCB, the spray with the brush has proved invaluable. Of any flux remover I've used, this is the best.

Always used this brand before to clean flux residuals, works like a champ.

The solvent works great. Very powerful stream using hose. Brush works well also. The only issue I have is the nozzle didn't connect to the can so depending on how it's held solvent will leak from the connection. Overall the product works great.
