All Hydrosorbent silica gel is manufactured to the highest specifications. Inert, non-toxic, and safe to use, our silica gel remains dry to the touch even when saturated. And once saturated, can be easily reactivated in any conventional oven for lifetime protection. By surface adsorption, silica gel absorbs excess humidity from the air. It prevents condensation within enclosed areas which cause irreparable damage (rust, corrosion, tarnish, oxidation; mildew, fungus, mold, odor, spoilage, spotting, toning, stains, etc.) to your collectibles. It needs no electricity and each package comes with built in indicators which turn from blue to pink when the silica gel is saturated with adsorbed moisture. Once saturated, our silica gel can be easily reactivated in any conventional oven and re-used for lifetime protection. Hydrosorbent silica gel granules are inert and non-toxic. They will not emit harmful vapors, stain, or cause any chemical reaction. Safe to use with foods, medicines, sensitive materials, electronics, films, etc.


The more tightly enclosed, the more vapor-proof you can make the storage area being protected, the better. Otherwise, your silica gel will "drink up" moisture from all outdoors, becoming saturated and requiring reactivation so frequently as to be inconvenient. It's worth it to do your best to make the protected area as vapor-proof as possible. Remove the protective pouch in which your Hydrosorbent unit is packaged. Position your Hydrosorbent unit on an exposed surface anywhere within the enclosed area to be protected. Examine the indicator from time to time to see if reactivation is required.


When you first use silica gel in the area to be protected, it may become saturated rather quickly as it "drinks up" residual moisture. Once the residual dampness is removed, you can maintain a dry condition with less frequent need to reactivate the silica gel. Reactivation times below are minimums. Sometimes, when the silica gel becomes overly saturated, it's good practice to extend the reactivation period. However, do not vary from the recommended temperatures.
750 Gram Unit: When the blue silica gel beneath the heat resistant inspection window turns pink, reactivate as follows: Place the entire unit (do not disassemble) in a vented 325 degree F oven for at least 3 hours. (Silica gel will gradually turn blue again.)
