Cleaned mine out with isopropyl 99% (NOT the 35%). ALL parts soaked in it, but carefull with the rubber parts ie. Speaker as it can dissolve. Cleaned board and all pieces with soft toothbrush. You can scrub the motherboard quite hard as components are attached very well. Dry out with silicabags. I keep my bags in an open container on the heater and when i use I put all parts in it and close firmly. I measured humidity inside to 18% when room is 65% humidity. Left it in there for 2 days. Assembled and works fine again. Had a water damage and tonnes of fungi everywhere inside!!
