--- Quote from: bob91343 --- I don't dispute the hazards of this solvent. However, I have been using it for decades and am a relatively healthy 86 years old. So maybe I will die from it but so far so good. --- End quote --- Yup, same :-) Still have heaps as well, and don't forget carbon tetrachloride - we'd wash our hands in it at high school !! Yup still alive :-) ahhhh memories |

Don't forget methyl ethyl ketone. That was the solvent of choice for a few years. |

Acetone is very powerful. But young women use it a lot to remove nail polish. |

I use a toothbrush and denatured alcohol for the first cleaning stage. I follow up with IPA and a different toothbrush. I then rinse under running cold tap water for about 30 seconds. I have high water pressure here, about 95 PSI. Then immediately dry the board with a hair brush dryer set to high temperature and high blow speed. The boards always end up looking very clean. No signs of damage to the silk screen or solder mask. |
