| How to clean up lab after big capacitor blew? |

Regarding cleaning, mind that that vapor / mist will land on every surface in sight. You may want to wash out some of your more intricate and unsealed electronics, just to make sure it's not gumming up the works. Electrolyte isn't so much corrosive in and of itself, but because it allows electrolysis, anything energized can eat itself to pieces! Tim |

Hiya I must have had a misspent childhood. I fondly remember connecting those large metal cased electrolytic capacitors from old radios across the mains when I was about 10 to see how big a hole I could make in my bedroom wall with the resulting projectile. (over 40 years ago!). The only requirement was a supply of replacement fuses!! >:D Cheers |

The scope display is toughened non-reflective glass so most cleaners should be fine but for the ABS of the case I'd just sponge it with warm soapy water and a good wipe dry afterwards. A little time on a window sill in the sun wouldn't hurt either. |

The only time I have blown a cap I put the mains through the low voltage side of a voltage/amp monitor. It wasn't just electrolyte it was copper dust perfectly plating the inside of the box, along with a burn mark on the carpet that perfectly matched the vent pattern in the side of the box. |

wow that's quite a mess! First off try soap and warm water, then progress to more hazardous chemicals. Anti-static foam cleaner is pretty good. Isopranol-alcohol is good at shifting oily/greasy stuff. Acetone - be careful on clear plastics with this, it WILL cloud/frost them up. I would try in that order. If you want cap explosion stories! I first started my career in a factory that repaired and built welding machines. We had a test area where units were tested as a technician would pop a few beads of weld down, units tended to be test with their lids off. The DC welders had a massive cap bank consisting of several 20,000uF, 200V electrolytic caps (about the size of a coke can) all screwed to a bus bar. one day there was an almighty 'POP!' as one of the welders was plugged in and the clanking of tin cans on the ground at the other end of this 15m long building! Caps and been screwed wrong way into bus bar and about 60V DC dumped across them! |
