I have come into possession of an RB4011iGS+5HacQ2HnD-IN. It works, but its life was spent in a cafe, and the outer casing at least has a thin layer of grease from (I guess) aerosolised grease in the air around the fryers. The top is worst, the bottom and sides seem much less affected. The four antennas are very greasy, and one seems broken. I haven't taken it apart yet to see if the innards are greasy too (don't have a small enough allen key). As it is passively cooled it seems likely that it'll be OK. It was running 24/7 in that environment, so I think anything that was going to catch fire would have done so by now :-) So I have two questions! 1: What's the best way to get the grease off (and possibly out of) this thing? Isopropyl alcohol doesn't do much. If I can get the PCB out of the case I might just wash the case with detergent and a brush :-) If I'm carefull I could probably do the same with the antennas. There are people on the Internet saying to do much the same thing with the PCB as well but... 2: Are the antennas on this model replaceable? They don't seem to want to unscrew or unplug.
