As long as you’re cautious of the common red flags, scouring Facebook Marketplace is a great way to score deals on secondhand furniture and home decor. That doesn’t mean every Marketplace find is a good one, though: Beyond following general safety guidelines (such as always meeting in a public place and never paying for the item before your meetup to avoid getting scammed), there are a few household items you should always skip buying secondhand.

Whether it’s old upholstery or items likely to have faulty wiring, these are the items you should never buy on Facebook Marketplace.

1. Vintage Lighting

You should always keep safety in mind when coordinating a Facebook Marketplace pick-up, but don’t forget to consider the safety factors of the item you’re purchasing, as well. Products like antique lamps are often sold with the original electrical components, which can be a major fire hazard. If you’re set on purchasing anything with potentially faulty wiring, just be prepared to have your secondhand find rewired by a qualified electrician.

2. Used Cleaning Devices

There’s nothing wrong with purchasing things like vacuums, mops, or other cleaning devices on Marketplace—as long as they’re listed as “new in box” and you can confirm they have never been used. If you’re purchasing something you’ll use to clean your home, you want to make sure the item itself is clean before bringing it home.

3. Old Upholstery 

Part of the thrill of secondhand shopping is finding something with great bones that just needs a bit of TLC. If you’re on the hunt for a DIY furniture flip, it’s best to stick to solid wood pieces, as upholstered items can pose more of a hazard. Even if you’re purchasing an item with the intention of having it re-covered, old upholstery has a higher risk of carrying bed bugs, pest infestations, and hard-to-eliminate odors. 

4. Anything Manufactured Before 1978 That May Contain Lead 

If you’re a seasoned vintage shopper, you’re likely familiar with the risks of lead in your antique finds. Any item produced before 1978 (when lead products were banned in the United States) carries a potential risk. Items more than 50 years old with highly pigmented paint, varnish, or glaze likely do contain lead—and because items listed on Marketplace likely don’t have an exact year or manufacturer listed, it’s best to steer clear of these altogether.

5. Recalled Products

Because Marketplace listings are created by individual people rather than brands themselves, it’s possible you’ll come across a for-sale item that’s previously been recalled by the manufacturer. Facebook typically flags listings for baby products (because things like cribs and bassinets are frequently recalled), but no matter what you’re shopping for, it’s worth doing a little research on the product name and brand to make sure the item you’re buying doesn’t have any recalls associated with it.
