How Do I Remove White Residues from my PCBs?

Streaks or spots of white residues left behind on PCBs are often indicators of using an improper cleaning solvent or flux remover.

To select a PCB cleaning fluid or flux remover to remove the white residues, use this very simplified progression from the mildest cleaners to the strongest. Starting with the mildest cleaner is recommended since it helps protect deleicate materials and components on the PCB from potential melting or other damage.

3.  Lead-Free Flux Remover – PowerClean™
