Perhaps I became too boisterous about water-wash flux, but let's face it, not
too many of us are passionate about good soldering.Â I do a lot of it, and I
have found the water-wash flux to give the best results.Â I use it on
everything (see warning below).Â I am obviosly passionate about it !Â It has
a HUGE advantage in allowing the user to apply minimum temperature and dwell,
because it does a beautiful job removing dirt and oxide.Â For example, if you
solder outside in the winter like I do, you will do beautifully well with a 45
watt pencil in 0 deg F weather, whereas you might be inclined to take a propane
torch.Â The water wash flux will make that much difference.
You do need to wash, or wipe with a wet cloth; otherwise, corrosion will start
(like on car battery terminals).Â As long as you wash, there is no issue.Â I
wash whole boards at home under running water.Â I did this with W9RE's,
W0NCL's and my IC-781 boards.Â Just blow dry them off.
Water-wash flux is aggressive, hence the need to wash.Â I would advise against
water-wash flux on objects that could trap flux.Â For example, I would not
water-wash flux RG8 braid going into a PL259 (I never solder braid on PL259s;
never had a problem).Â I do however, water-wash flux the center terminal.
I guarantee that using the water-wash flux will make a tremendous difference in
your soldering results.
