When you purchase alcohol to use as cleanup it's best to get the highest concentration you can get, else, there is a risk of it leaving a residue and the evaporation rate is much slower. Most drug stores sell 91% or higher if you ask/look for it. 60% is more common. Higher % is better for cleaning and evaporates more cleanly. Jer

This aims to ensure that chemicals such as flux cleaners and contact cleaners will not damage the plastics that are used in the majority of components. In return, component manufacturers try to avoid using plastics that would be damaged by solvents in common use. Undiluted acetone is not part of that agreement because it's simply too aggressive, as Fred describes. Although electronics-grade solvents are more expensive than bulk commodity solvents like acetone, for peace of mind they are worth the extra cost. 73 from Ian GM3SEK ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to je...@carolinaheli.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
