837-P Water Soluble Flux Pen

https://www.mgchemicals.com/products/soldering-supplies/flux-pens/water-soluble-flux-pen/

Our Water Soluble Flux Pen contains a water-soluble soldering flux. The flux has a neutral ρH at room temperature and becomes highly activated at soldering temperatures. Post-soldering flux residues must be cleaned, but are easily removed with water. The 837-P is an ideal flux pen for rework. It is designed for the prototyping, rework and repair of conventional and surface mount circuit boards.
