Hello ladies and gentlemen! also a computer network engineer, i also hold an FCC license to repair electronic radios, i can tell you that i have used dozens of soldering iron tip re-tinning compounds, mainly used to remove oxidation and deposits, and i can tell you that i have tried dozens of other brands that have been less than marginally effective. Compositions for retinning/cleaning solders and tips. I would give this brand an 11 on a scale of 1 to 10. Invest a little money and you will be amazed! the job I think he does and many other PROFESSIONALS and similar ELECTRONICS REPAIR PERSONNEL!For trying this brand AND IT'S NOTHING!I'm not used to making product reviews but felt compelled after seeing this one product had used! The only thing that could be improved is the larger size, including the applicator brush! Sincerely, oh one more thing, like all solder and tip connections, the fumes are toxic and can come from dormancy. Do yourself a favor, spend about $40 and buy a smoke evacuator, which you can get here at Revain. Trust me on the health is worth it ! dr Thomas J. Contartesi. FAAC
