Additional Uses for Silica Gel

When most people get a packet of silica gel in a shoe box or beef jerky packet, their instinct is to toss it. But savvy DIYers have long known that the omnipresent desiccants are good for a lot more than keeping jerky dry. Here are a few uses, including some great tips sent in by readers.

Dry Out a Wet Cell Phone

If your phone becomes the unfortunate victim of a spill or swim, you can still rescue it—you just need to act fast.

Leave it there at least overnight before powering it on again.

Extend the Life of Razor Blades

It is understood that oxidation on razor blades causes premature dulling. I keep a Tupperware half full of silica gel in my medicine cabinet. After each shave, I blot any residual water off the blade and store the razor in the Tupperware with the silica gel.

If you’re taking your camera out into the cold, it can face serious condensation when you bring it back into a warm room. Remove the battery and memory card, and place the camera in a bowl of silica gel to suck up the moisture.

Dry Out Wet Fishing Flies

Being an avid fly fisherman, use silica to dry out my flies when fishing on a favourite stream. Crush or ground the silica into powder form, then place it in a film canister. When your fly becomes waterlogged, place it into the canister, put the cap on, shake it for a bit, and voila
