Save money with kitty litter even if you don’t have a cat
When I shared my post about tools to our Facebook page, one of the readers brought up the subject of rust prevention. It initiated a good discussion because no one wants to spend a bunch of money on tools only to have them become unserviceable due to corrosion. When one of the commenters recommended using desiccant packs, it reminded me of some homemade ones that we made back on ZTC, out of kitty litter, no less.
Science types should feel free to shoot holes in my thinking, but it seems to me that the active ingredient in many commercially-available desiccant packs is silica. While not the most common variety available, we also found that we could purchase large bags of cat litter made from silica. Putting two and two together, we decided to buy a bag of kitty litter, and make our own custom-sized desiccant packs.
Note: This entire post is about using kitty litter made from silica, not the more common clay variety.
The how-to details:
To hold the desiccant we purchased several packs of ladies knee-high nylons from the dollar store. After filling them until they were about the same shape as a medium-sized cucumber, we sealed off the top with a tie wrap (zip tie).
What did we do with them? We put one or two in the bottom of each of our hanging lockers, and also some in other storage areas. Did they work? Based solely on empirical data, I’d say yes, as we never had any problems with mold in our lockers.
What is the benefit of doing this? Simply cost savings. A quick search on Amazon shows me that 1 lb. silica desiccant packs sell for about 15 bucks, while a 4 lb bag of silica kitty litter can be purchased for only 10 dollars (that’s only $2.50 per pound).
