Review: MG Chemicals Electrosolve Contact Cleaner – A Must-Have for Cleaning Old Mining Rigs - I picked up the MG Chemicals 409B Electrosolve Zero Residue Contact Cleaner (15.45 fl oz) to clean some old, dusty mining rigs, and it worked wonders. After months of running 24/7, my miners had collected a ton of dust and grime, and this cleaner made them look and perform almost like new. What I really like is that it dries quickly without leaving any residue, so I don’t have to worry about moisture or film causing shorts. It’s safe on plastics and electronics, which is perfect for circuit boards, fans, and power supply connectors. The spray nozzle makes it easy to get into tight spots, blowing away dust and cleaning contacts thoroughly. ✅ Pros: Zero residue formula — safe for electronics Cleans dust, dirt, and oxidation from boards and connectors Quick-drying, no waiting around Large 15.45 fl oz can lasts a long time Works great on mining rigs and other electronics ❌ Cons: Strong odor while spraying (use in a ventilated area) 💡 Tips: Always power down and unplug your miners before cleaning. Use short bursts instead of long sprays to avoid over-saturation. Do this cleaning outside or in a well-ventilated area. Pair with a can of compressed air for best results — blow out dust first, then use the cleaner on contacts. Bottom Line: The MG Chemicals 409B Electrosolve is a powerful and reliable cleaner for electronics. It brought my old miners back to life by safely removing dust and oxidation, and I’ll definitely keep a can on hand for future maintenance.
Review: Works. Took several squirts. - I don't know how it works but it does. I opened the hood of my old receiver and accessed the innards side of the volume knob. After Several squirts and a lot of rapid turning of the knob, the crackling sound disappeared.

### ⭐⭐⭐⭐⭐ really good stuff
*by R***S on May 15, 2024*

This is really good stuff for anyone who likes to work on things that are electronic. Potentiometers create Gunk and debris inside of them and this cleans it out. I use this on a marshall guitar amp, my washing machine, and a few other electronics that I decided to clean just because. Works really well.
