Healthy Living: Health Dos & Don'ts of Buying Used

This is what smoking leaves behind in clothes, furniture, curtains, and pretty much everything else. It builds up over time and can last for weeks. Stay away from items you know came from the home of someone who smoked. Since you don't always know for sure, it's best to give everything you buy used a thorough cleaning.

Cribs made before June 2011 must not be used or sold because safety standards have changed. There also are strict rules for things like height, how close together the slats must be, and how the mattress fits. When you add it all up, it's not worth the risk.

Make sure the safety straps are in good working order and that no sharp parts, like screws, jut out from anywhere. And check the company's website to be sure it hasn't been recalled. Fold and unfold strollers to see if they're sturdy. Test that high chairs aren't wobbly and trays snap firmly into place. Keep in mind that some older models may not be tip-proof.

It might seem like a good deal -- until you have to pay for a doctor's visit and some medication. Makeup and brushes touch your hands, eyes, and mouth. That makes those little containers breeding grounds for all kinds of germs. Even the testers in stores can be a bad idea. You can get skin rashes and serious infections. And used makeup may no longer have labels that list ingredients and warnings and tell you how to use them safely.

If you're concerned about bedbugs -- and most of the time, you probably should be -- go straight to the dryer. Washing alone won't kill them. Run everything through on high heat for 30 minutes. Take any bags the items came in to your outside trash right away. For things that can't go into the washer and dryer, dry cleaning will get the job done.

From bikes to horse riding, most helmets are made to hold up through only one crash. Or one drop on a hard surface. Once that happens, the foam inside squeezes and won't protect you the same way, even if it looks fine. Plus, older helmets don't necessarily meet the same safety standards as new ones, and the materials can break down over time.

The bulbs in tall torchiere lamps can get twice as hot as your oven. If a curtain touches it, it can catch fire. Look for one with a wire or glass shield over the bulb. And even if the label says otherwise, don't go any higher than a 300-watt bulb. It's also good to check for a polarized plug, where one side is wider than the other. And make sure the cord isn't frayed and that the lamp doesn't have any bent, rusted, or loose parts.

While used clothing is generally fine, you don't want these items used. Because of where they sit on your body, a whole other level of germs come into play. That includes genital infections and small amounts of poop. And swimsuits tend to wear out quickly, so you're not really saving much money in the long run.

These critters can crawl into the tiniest seam or crack and go a year without eating. Once you have them, they're brutal to get out. They can be in most types of used furniture, but you're more likely to find them in mattresses or items with soft fabric, like sofas. Check these things very closely, looking for bugs, eggs, and signs of their poop, which looks like tiny black dots.

If you're allergic to dogs or cats, it's probably the dried skin flakes, known as dander, that affect you. And they're sticky, so they easily cling to clothes and other fabrics. Look for hair or fur to give you a warning sign. Washing clothes and linens will help. And furniture made of wood is a lot easier to clean than that almost perfect vintage sofa.

Like car seats and helmets, there's just too much you can't know about their history. Were they in an accident? Driven at really high speeds? Towing loads that were too heavy? All those can cause damage you can't see. And every tire has an expiration date. They're only good for 6 years, whether you use them often or not.

Water and electricity are deadly together. As long as it's plugged in, a hair dryer has electricity raring to go, even if it's turned off. Newer ones protect you with a bulky plug that has red and yellow switches on it. It cuts off the supply of electricity if it gets wet. Don't buy older models that don't have this feature. And check that the cord is in good shape.

From washing machines to strollers, pretty much anything can be recalled for safety reasons. To find out if there's been one for something you're interested in buying, get the brand and model, then check the manufacturer's website. Older products may no longer be on recall lists, so you may want to give the company a call to be sure. You can also check with the government's Consumer Product Safety Commission at www.cpsc.gov.
