# Branson EC (may be discontinued, definitely at least back ordered) "Best electronics cleaner ever. I will never use any other cleaner. I tried the cheap alternatives everyone on the electronics forums recommended and obviously they have never tried this stuff. Heavily abused PCBs come out looking brand new. No scrubbing. I use about 100ml per gallon of distilled water at a temp of 65C for 4 minutes. I bought it here for $126 but realized I could buy it elsewhere for $34. That's not a fault of the product but of the seller Discountland. I'll just have to shop around next time." Use in Ultrasonic Cleaner: https://www.youtube.com/watch?v=ls4hTFee7Qw "Based on my experience mixing formula is 3% of Branson EC concentrate + 97% of Distilled Water @ 50 -> 55°C" still has stock: like $70 shipped https://www.techni-tool.com/product/10163634-100-955-920 ## simple green 1:30 dilution try? # alternate method - rinse with tap water - gently scrub with dish soap and a tooth brush - rinse with tap water - shake vigorously, swing it around to make the water fly off - spray with IPA 99+, scrub gently - shake vigorously, swing it around to make the alcohol fly off - put in a toaster oven on 100F convect, door cracked open for about 15 minutes And it's ready to use at this point [https://www.youtube.com/watch?v=1mnBydEHg_4](https://www.youtube.com/watch?v=1mnBydEHg_4) (this is a plain SE board, that doesn't suffer the cap plague so it was mostly pointless in this video)
