+One - Insulated glasses, tumblers, and thermoses

False!

+Two - Bathroom accessories

True! Scrubbing your toothbrush clean can be gross. You've got toothpaste which feels so gross when it's wet, and just icky when you try to scratch it off. You've got soap residue which is slimy when wet and gross and sticky when dry. Then you have mold that can build up due to how warm and wet it gets in your bathroom. (Unless you're taking cold showers every day? Some people do.) Fortunately, your dishwasher is here to save the day. You can toss in all sorts of things from your bathroom, and they'll come out clean all without having to get things built up under your nails.

+Three - Acrylic dishes

False!

+Four - Plastic Hairbrushes

True! Have you ever looked at one of your hairbrushes after taking off the hair and noticed that it still had buildup on it? That's a mix of styling proucts and the natural oils from your scalp. Thankfully, you can get rid of that by putting it through the dishwasher. Ideally, you'd do this once a month. Just make sure not to do this with wooden hair brushes or ones with natural boar bristles. Both can be damaged by the soap and the hot water from the dishwasher.

+Five - Ashtrays

False! Ash trays are covered in, well, ash. Because of how fine that is, it can become clogged in your dishwasher's filter and lead to a dishwasher that just won't drain. We suggest using soap and an old toothbrush if you want to get your ashtrays looking good as new.

+ Six - Baseball caps

True! Oh no! Some jerk at your kid's football game got mustard on your baseball cap. It's cool, your dishwasher can clean it right up. Don't put soap on it, just rinse with cold water and put it on the top rack. We will say that you need to double check what the brim is made of first though. If it's a newer cap, you should be fine. But many older caps had cardboard brims and that can't go into the dishwasher.

+Seven - Wineglasses

False! While there are many glass makers that claim their wares can go through the dishwasher, this is only true on a technicality. While the glass can stand up to hundreds of cycles with harsh detergents without being damaged, they can't stand up to the dishwasher itself, or human error. Yup. Whether it's the glass being taller than the dishwasher itself or glasses being rattled around and shoved against the tiens and each other, it's very likley that your wine glasses will end up broken by putting them through the dishwasher.

+Eight - Ceramic knives

False! Not only will your ceramic knives likely catch on the coating of your rack, but they can also chip from being jostled around druing the wash cycle.

+Nine - Vacuum Cleaner Attachments

True! Since they're made of a heavy duty plastic, most are dishwasher safe. Make sure to double check your owners manual first, but if they give the all clear, you can run a load of just the different attachments and brushes and get them nice and clean.

+Ten - Lead Crystal

False! Crystal is heat sensitive, so it's very prone to cracking, and detergent can cause them to chip. Most importantly, lead can be leached out of your crystal, leaving them cloudy, and if it's not all washed away, potentially hazardous to your health.

+Eleven - Kitchen Tools - Metal and plastic only

True! Many of the things you use around your kitchen can be put through the dishwasher to be cleaned and sterilized themselves. Sponges, scrub brushes, drain plugs, sturdy plastic cutting boards or drainage trays, even plastic or metal shelving you have around the kitchen can go through the dishwasher provided you make room for it.

+Twelve - Flip-flops

True! Just getting back from the beach and you want to get your flops clean again? No worries. Your dishwasher has you covered. Rinse off any remaining dirt, mud, or sand either in your kitchen sink or and then loop the tongs around one of the tines on the top rack. Turn the dishwasher on like you normally would and you're good to go! Your flops will be looking lovely in a short run cycle.

+Thirteen - Wood -

Includes wooden spoons, bowls, chopping boards and wooden-handled knives. False! Wooden tools will absorb water and crack over time. It won't show at first, but the water will seep in and force the fibers of the wood apart slowly, until eventually the pieces split apart. So unless you're keen on splinters, we advse washing these lovely tools by hand.

+Fourteen - Refrigerator Components

True! Do you have any removeable bits in your refrigerator? The fruit and veggie drawers, that removeable butter tray, the shelves that you can move around for maximum storage capability? all of those can go into the dishwasher. Every three months or so is a great way to keep your dishwasher clean and sparkly. Now, if there are any metal shelves, you'll want to make sure that they're coated in rubber so that they don't chip the inside of your dishwasher. Make sure to dry them completely before with a microfiber cloth to keep them from growing mold.

+Fifteen - Gardening Tools

True! While you might usually give them a quick rinse outside in between uses, a more thorough cleaning is good before you put them away for winter. To that end, rinse off any leftover dirt, and make sure they're not aluminum before popping them in. Make sure to dry them by hand with a clean towel once they're out, and thoroughly to prevent rust.

+Sixteen - Pewter

False! Pewter is a very soft metal, with a melting point of just 400* Farenheit. It's all too easy for it to be warped by the heat of the dishwasher. On top of that the soaps you use or the foods you eat can cause pewter to become discolored.

+Seventeen - Graters and Sieves

False! The blades on the bottom of your grates have sharp edges that can either corrode or break off in the dishwasher. Seives on the other hand are more likely to rust.

+Eighteen - Metal Vent Covers

True! If your top rack is removeable you can send these through the dishwasher every six months, not only will they look nicer, but they'll also do better at keeping your house free from dust. Be sure to dry them completely before reinstalling them.
