The better thing to do than trying to absorb the moisture is do what the industry does, displace it. The easiest home displacment method is simply 94% or better Isopropyl alcohol. A bath in alcohol gets places the water did and pushes it out, and then the alcohol itself evaporates quickly. This also tends to remove all the residuals that cause post water exposure corrosion. > > Alternatively, if you have an electric oven or toaster oven, you could > > bake it for an hour or so at 125 degrees.?

Electronic components are rated for storage to 150 deg C, prebake in circuit fabrication is usually done at 125 deg C to drive off all moisture before soldering. The note on a gas oven is spot on, as your self defeating. After the alcohol bath room temp usually works fine if given time > Sounds like the best plan.

Rinse with proper stuff, then repeat. I would never recommend a water bath that is not immediatly followed by an alcohol or other (industry usually uses Hot Freon TF) bath for any situation. > > Thanks for your analysis. > > -- > Regards, > Dick Steffens -- Rod Grimes [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
