Review on Premium SRA Sal Ammoniac Tinning Block - 100 Grams: Efficient Soldering Solution by Black Croom

This material is great for cleaning all types of tips and soldering iron tips, especially before starting. It's especially good when I use pure copper homemade bits in cheaper auto irons. This bar-sized unit will give you a LONG time at a fantastic price. Anyone who solders a lot should have an ammonia block under their soldering tools, nothing makes cleaning and extending the life of soldering tips easier.
