SunFounder Solder Tip Cleaner

While a brass sponge removes surface debris, this compound chemically reacts with the tip to dissolve stubborn oxidation and re-tin the surface. It is designed for deep cleaning when a sponge is no longer effective at restoring heat transfer.

Yes, the lead-free formula is safe for use on all standard soldering iron tips. It is specifically formulated without diammonium phosphate, which prevents the premature degradation often caused by harsher cleaning agents.

The grinding headstone is intended for heavy-duty maintenance. Use it only when your tip has significant, hardened oxidation that the chemical tinner cannot remove on its own.

No, the compound is designed to be wiped away after the tip is re-tinned. Once you have dipped the hot tip into the compound and cleaned it on a sponge, the tip should be shiny and ready for immediate use.

You don't need to use it every time you solder. Use it periodically as part of your maintenance routine, or whenever you notice the tip is no longer wetting properly with solder.
