Flux Removers

MG Chemicals’ flux removers come in convenient aerosol, liquid and pen formats, and are suitable for maintenance and repair operations, service centers, prototyping, maker projects, and small scale electronics production.

We offer two options for dissolving and rinsing flux residue: a safe-on-plastics formula for general flux removal, and an aggressive alternative for removing difficult baked on flux.

Flux Remover for PC Boards is plastic safe and designed for general applications. It is effective at both dissolving flux and rinsing dissolved residues from boards.

Heavy Duty Flux Remover is highly aggressive and dissolves the most stubbornly burnt on-flux. However, it is not plastic safe, and therefore it is best used on the solder side of boards or for careful spot removal on populated boards.

Removing Flux

Flux removal is a two-step process. Step one is dissolving the flux, and step two is rinsing the dissolved flux off of the board so that it does not redeposit as white residue. Either of our flux removers can rinse as well as dissolve flux; however, our 406B Super Wash makes an extra-effective rinsing agent, because it is very fast-drying and also plastic-safe. It will quickly wash away both the slower-drying flux remover and the dissolved flux, producing a clean dry board in seconds, providing an efficient and effective flux removal process.
