Heated mat.

For dunked stuff it's best to take any power sources out and keep wet. Then dissasemble as much as is sensible wash the bits under clean running water dry off with something absorbent then give it the warm place for a day or two treatment.

I think for your needs a small lightly ventilated box so you can bring the whole object up to 30 or 40C to dry would be better than just a warm mat that will really only heat the bits it's touching. As this needs to be warm for a day or three or longer some sort of powered heat source rather than a Hottie or hotwater bottle is required. We are only talking a small box with not a great deal of ventilation, so I suspect a 21W 12V brake light bulb would do, if that gets too warm try a tail light bulb.

I'll still use the sonic bath though, after all, if it comes to this it is shit or bust. Wife's phone was in her pocket and she fell into a dirty stream camera pocket down and when she brought it home, you could see mud everywhere.

Learned something from the man at the pet shop today, he does something along the same lines with cameras and phones. He told me that if you take the battery out and look at the contact end of the case, you might see a red component, if you can, the phone is beyond economical repair. It's there to tell the engineer what to do next, repair or bin.

From your description, you are slowly turning me to the idea. I just hope that I still have an old 12 V transformer I can use, as the main one has a few transceivers powered by it and is switched off when the radio shack is not in use.

A bit of thin MDF and some glue would produce an enclosure.

Thanks.

That sounds like an urban myth to me. Some batteries have a little slider that can reveal a green or red splodge. The slider doesn't do anything other than cover one or the other splodges which the user can set to indicate the charge state of the battery.

If powering a brake bulb is a problem a 15W pygmy mains bulb would do, with the obvious caveats about mains...

AFAIK there are some phones with a water detector fitted. It changes colour and your warranty is void if it has tripped.

I thought about that this morning, along with a dimmer switch to set the temp, depending the season.

All you need's a thin bit of sheet steel and a 12-20w transformer. Cut the secondary winding off and add a single turn of 2.5mm^2 from some T&E. Connect this to each side of the tin pad, and there ya go, heat. Since the specs of these types of haeters are very approximate, check the transformer doesnt get too hot to hold in use. It can take as long as an hour to reach max temp.
