Found an old receiver remote that the batteries had corroded in. It doesn't work with cleaning and new batteries. Is it

[Dennis S]

I ran across a long-lost remote to a 20+year-old Technics receiver. The batteries were corroded, but not really bad. I cleaned the corrosion with a toothpick and toothbrush and loaded some new batteries, but it doesn't work. I've cleaned behind the negative metal flaps as good as I physically can. Is there some kind of liquid that it can be soaked in safely to clean it? Does the corrosion, which wasn't terribly bad, eat its way into the innards of the remote?

I got one like this, a fiberglass corrosion cleaning pen. Works great!

or set of three for all grades of corrosion: http://www.amazon.com/3pc-Pen-Style-Scra...d_sim_hi_5

A nail file will also work. You can take it apart and check the PCB for acid damage. If the traces are toast you *can* repair it, but usually not worth the effort

You could trace where the new battery voltage goes/or doesn't.

I saw a 6 in 1 universal remote at the DollarTree yesterday that might work. It will only cost you $1 to find out.

perhaps one of them Home Depot or Shack sold universal remotes might work?

A little vinegar on the end of a q-tip?

[Dennis S]

The vinegar solution sounds like #1 and the Dollar Tree remote is #2. I don't have a gizmo like Billb suggested.

You probably have corrosion elsewhere as the batteries off-gassed. Sorry, but:
