Harris Stay-Clean Flux for Metal Joining
Harris Stay-Clean liquid flux comes in an 80 oz bottle designed for general-purpose soldering on brass, copper, nickel, stainless steel and steel. It suits both lead-free and leaded solder alloys including tin/antimony and tin/lead. The inorganic-acid formula meets the A-A-51145SC standard. It is not intended for electrical or electronic work.
Capacity and Active Temperature Range
The 80 oz container provides ample volume for repeated workshop jobs while the flux remains active up to 700 °F, giving headroom for high-temperature joints. Above that temperature the flux breaks down and will no longer protect the workpiece. Clean-up requires a dedicated flux remover rather than water alone.
Bottle Format and Usage Constraints
The liquid stays in a bottle that pours directly onto the joint, so no separate pot or brush is mandated by the packaging. Because the formulation contains chemicals listed under California Proposition 65 for cancer and reproductive harm, users must follow safe-handling practices and avoid electrical or electronic applications where residue could cause corrosion.

Questions about this item
Will the 80 oz bottle of Stay-Clean flux work with the lead-free solder I already use for copper pipe?
The flux is formulated for both lead-free and leaded solders including tin/antimony and tin/lead alloys, so it is compatible with the solder you have on hand.
How can I verify the flux is still active after I open the bottle?
The liquid should remain clear and flow freely; when heated on copper or brass it will bubble and clean the surface up to the 700 Degrees F maximum active temperature.
Does the 80 oz bottle include a brush or do I need to buy an applicator separately?
The container is a plain bottle without a built-in brush, so a separate flux brush or applicator will be needed for application.
