Rain from a small leak got into my S7070 and entered through the ventilation and I'm wondering if it's possible that by leaving it off for a day or two that it will possibly dry up and still work. Is this likely? It should be noted that the unit was in standby at the time.
Thankfully I no longer use it but the olds were gonna use it for the living room so that's temporarily up in the air for the time being.
Well my old's think it will work so they've dried it out with a hairdryer (the best they can) and will probably test it in a few days. I, personally, believe it won't do jack so I'm not confident about this whatsoever.
Last thing I used it on was an admittedly cheap LED torch. It eliminated an awful lot of contact resistance (several points of contact within the torch) and I'm pretty sure I'll get longer battery life.
I reckon you would use 1/5th of a can but it would be well worth a go. Just disassemble and drown it in the stuff so it runs off everywhere. That is what it is supposed to do.
