The first gas mask was patented in 1849, and it's still a good thing to have to protect you from all the dust, dirt, pollen, mildew, mold, germs, and grime found in today's ?average? home. Got a house full of kids, pets, and a handyman husband? Then you probably have all this and more! Today you'll learn how to trim down housework and make your home a home ?clean? home. As for germs, the kitchen sponge is a virtual science experiment, with more germs in it than on the average toilet seat. To zap 'em, microwave for one minute after each use. To reduce mold and mildew in the bathroom, apply a penetrating sealer on tile and grout and squeegee or towel-dry moisture after showers. To eliminate up to 80 percent of tracked-in dirt, put good door mats at every entry (including the garage and patio or deck.) Increase two quick wipes to three or four good ones and add a second mat inside, or, like the Japanese, just say: ?leave your shoes at the door, please.?
