Review on 🔥 Chemtronics 80-3-5 Desoldering Braid, Rosin Flux, 5ft by Abdirahman Elmer

This stuff works very well. I like to cut off a 1 inch piece, hold it in the middle with needle nose pliers and use each end once. I've found that it's best to place it on top of the solder you want to remove and press it down with a soldering iron. What it doesn't do is suck solder out of holes. Coupled with a good solder sucker and a resistor to get solder out of holes, you can clean almost anything if the solder sucker isn't doing its job.
