Soldering Iron Tip Refresher Cleaning Paste - 1PCS

It definitely cleans the tip of your soldering iron

Dip the tip in that, and it seems to turn into some type of acid, it dissolves the crud, wipe it on a damp sponge and your tip becomes shining new. Only need to use it after you've left the iron on too long, or abused the iron to burn a hole in the foam.

A LITTLE MAINTANCE GOES A LONG WAY...

Makes tips brand new
