Everything is tougher in the cube
Water wipes are good for cleaning stuff I clean my glasses, fishing rods, frying pan allsorts with them they might work, Google might have a good cleaning solution for the material you are trying to clean?
General alarm with receiver question? Do all alarms with receivers have a slight delay to the receiver? My soniks seem to as did my old fox sounder box as it travelled up the wire ð but as these are silent do they still transmit slightly slower than the line movement like if I had my alarm volume down ?
