| Blue Battery Acid Corrosion on Circuitry |
| (1/2) > >> |
| AquaSentinel:
Hi n00b here. I opened this 20 year old toy up. Lots of battery acid. There’s blue corrosion. Cleaned up the terminal as best I could. Thought contact would work. Not working. Looks like the blue corrosion(?) has advanced to circuitry. Can see it through the side on the back of the board. I can’t access this side because the battery terminal was soldered on the other side after insertion with plastic barrier between the 2 pieces. Can see the blue has made it through to the front side if you look carefully. Wondering if it’s possible to dunk this thing in some sort of chemical that will remove the blue corrosion & not damage the rest. You don’t know what you don’t know. Also does blue corrosion mean something. I’ve seen plenty that isn’t blue. Many thanx. |

Dipping it will certainly destroy something - like the motor. Probably best to disassemble it, then mechanically clean the PCB and everything that looks contaminated, some vinegar might help; rinse with destilled water. Unfortunately, if you don't remove it, it will creep and destroy more and more of that wonderful piece. |
| AquaSentinel:
Wow! I didn’t know it would continue to deteriorate. I can’t clean it because it was soldered together around the plastic & can’t be removed. So I can’t get to the damaged side. |

The blue corrosion is alkaline, so you'd neutralize it with a mild acid like vinegar. It'll bubble when you brush some vinegar on it. Best to disassemble and clean. Those tabs can be desoldered with great care and the right equipment. Another option would be to remove the motor + switch, and then give with whole thing a vinegar bath scrub, fully rinse with clean water, and then fully dry it out without melting the plastic. Is there any sort of speaker for the R2D2 beeps? If so, that should be removed/protected from washing also. |
| AquaSentinel:
It has a remote that contains the speaker. Has the blue “corrosion” possibly damaged the piece permanently? Or does it just stop the electrical flow? I’m wondering scientifically what’s going on here. |
