Squirt bottles and Pripps

Simply put the Prips in the refrigerator for about a day after
“cooking” … then pour off the clear solution, leaving the
crystals that cause the clogging behind. If you’d like to take it
further, run the liquid through a double coffee filter.

If this doesn’t work… then it’s time to get out the black candles
and incense:)

Since we work so hard to get pieces free of all grease before
soldering, I was surprised to hear that petroleum jelly or mineral
oil are binders in paste solder…How does that work? Doesn’t the
oil inhibit solder flow?
