For applications such as printed circuit boards, switches, and heat sinks, these removers get rid of any residue left behind by no-clean flux. Product regulations restrict sales to the listed jurisdictions/areas.

Lead-free and rosin flux removers are designed to remove the flux residue but not impact the remaining solder. It's common to use this remover when soldering with lead-free and tin/lead solders.

Pens are best for spot cleaning and precise removal.
