I took the capacitors off my A4000 board in preparation for washing, took out the socketed chips ( Super Buster, Kickstart & one socketed logic chip U103 ), took pictures before and after.
The initial result from washing for 40 minutes in a bath of roughly 1:6 vinegar / water isn't enthralling, the board is certainly cleaner but it hasn't done enough with the areas damaged by battery acid and capacitor leak. I will try again tomorrow with a mixture of lemon juice and water to see how well that cleans up.
I have also made a plate to fit the A4000 board on to be heated to 120 degrees C before resoldering the capacitors, I built a digital thermometer last week based on TMP36. When the project is complete and working to my satisfaction then I will post photos, videos and explanations / descriptions for any interested party.
