Too much De-oxit on the PRGM/ALPHA toggle key? - Ángel Martin - 05-02-2017 07:10 PM Several months ago (can't even find the thread anymore) I asked about getting an unresponsive ALPHA key to work . Back then De-oxit was suggested as worth trying, so I got some of it with the intention of giving it a try... So I finally did yesterday, but silly me after looking at the opened halve I sort of gave up accessing the key dome from inside - so I poured it from the outside, thru the tiny gaps between the key and the enclosure. It's been 24 hours "drying" upside down, but I can still see some liquid squeezing out when pressing the keys sideways. In all likelihood I may have put too much and now I worry about shortcuts or other bad stuff. Is that a possibility? RE: Too much De-oxit on the PRGM/ALPHA toggle key? - Dave Frederickson - 05-02-2017 07:21 PM According to the Directions for Use, the 5% concentration can be left to evaporate, but the 100% concentration should have the excess wiped off. Which formulation did you use? RE: Too much De-oxit on the PRGM/ALPHA toggle key? - Ángel Martin - 05-02-2017 07:25 PM Not really sure of the concentration. It's the Deoxit-Gold D-series, p/n G100l-2C. It's very oily (viscous) and doesn't feel like it'll evaporate soon... if at all. PS. it's the 100% tube so i guess it won't dry off any soon :-( RE: Too much De-oxit on the PRGM/ALPHA toggle key? - Dave Frederickson - 05-02-2017 07:40 PM You might try using a can of compressed air to blow out the excess and then let it evaporate. From the part number you've selected the Gold, not the D-Series. The Gold is more of a preservative/contact enhancer and it sounds like you need to remove some contamination. The D-Series would probably work better. RE: Too much De-oxit on the PRGM/ALPHA toggle key? - 4ster - 05-03-2017 12:30 AM I use Deoxit Gold and D series to maintain an electrical plug used in a salt water environment. The routine I use is to spray D5 to clean/deoxidize and then when that is done/dry I treat the contacts with Gold. The Gold is really only a barrier coating. My final step, that you probably DON'T want to do, is to apply a drop of mineral oil to the plug before making the connection. Here is a link describing the various products: Deoxit RE: Too much De-oxit on the PRGM/ALPHA toggle key? - Dave Frederickson - 05-03-2017 04:11 AM (05-03-2017 12:30 AM)4ster Wrote: I use Deoxit Gold and D series to maintain an electrical plug used in a salt water environment.
