    31 Problem-Solving Products Reviewers Say Worked “Like A Charm”

    Whiter teeth, happier plants, shinier jewelry, and more results you'll undoubtedly be charmed by.

    We hope you love the products we recommend! All of them were independently selected by our editors. Just so you know, BuzzFeed may collect a share of sales or other compensation from the links on this page if you decide to shop from them. Oh, and FYI — prices are accurate and items in stock as of time of publication.

    1. A painless, mint-flavored teeth-whitening pen because traditional strips are tough to use, expensive, and can leave you with teeth sensitivity that is, in my professional opinion, NO fun. With this pen you can get instant results. And the best part? No lingering sensitivity. 

    Promising review: "I have to say, I was skeptical about this product from all the TikTok craze about it but after trying it out, it really does work. I’ve used whitening strips before but those usually hurt my sensitive teeth, and I hate the taste of some of the other gels on the market. This one was super easy and didn’t hurt my teeth at all and didn’t taste much different than my regular toothpaste since I got the mint flavored one. I used it for a few weeks before my brother’s wedding and it worked like a charm. I noticed visible results in only a couple of days and was able to keep using it until I reached my desired shade of white. 10/10 would recommend for anyone with sensitive teeth and tastes!" —Victoria Bravo

    2. A pack of biodegradable foaming drain cleaning tablets to take care of all the out-of-sight grime clogging (and stinking) up your garbage disposal.

    amazon.com

    Promising review: "This is fantastic! Very easy and quick to use, and works like a charm. Seeing the blue foam bubbling up from the sink is very satisfying!" —Mirjam Dijkxhoorn

    Get a four-pack from Amazon for $3.98.

    3. A bottle of wine drops so your before-bed glass of wine doesn't end in a morning-after headache. A few drops added to your glass works to naturally reduce sulfites and tannins in wine — the frequent culprit of "I had one glass, this can't be a hangover" headaches.

    a glass of wine and the dropper bottle with text reading "trying these drops out. I've been getting headaches one glass in recently. So far they are working and it makes the wine really smooth."

    Promising review: "Works like a charm if you're sensitive to tannins or sulfites. You’ll be able to drink wine again. It's not a gimmick." —mannefitz

    Get it from Amazon for $14.99.

    4. A gluten- and cruelty-free lengthening mascara if you're tired of getting excited about mascaras that never live up to their promises. This one is different — or at least according to the 176,000+ 5-star reviews.

    amazon.com, amazon.com

    Promising review: "This extends and lengthens like a charm. Great product for such an affordable price. Will definitely purchase again." —Jesse

    Get it from Amazon for $4.99.

    5. A pack of Miracle-Gro plant food spikes for helping all your plant babies live their healthiest, happiest indoor lives. One fertilizer spike continuously feeds plants with nutrients they need to thrive for up to two months!

    amazon.com

    Promising review: "My mother has always used the MiracleGro plant food spikes, so I grew up familiar with them. Of all the products out there, these are the easiest to use and have never burned my plants. It works like a charm for plants that are droopy and out of sorts!" —BlueFug8

    Get a 24-pack from Amazon for $2.79.

    6. An organic cotton bacon sponge that can absorb up to 10 TIMES its weight in grease. No more wasting a roll of paper towels every time the sweet smell of bacon calls your name. *AND* it washes up for reuse with a little dish soap pre-soak before tossing it in the washing machine.

    Green City Living is a small biz based in Denver that specializes in eco-friendly home goods. They donate 2.5% of sales to the Climate Emergency Fund, an organization that supports climate activists.

    Promising review: "My husband calls the Bacon Sponge my Baconator! Since the lockdown and the scarcity of paper goods, I've reevaluated my carbon footprint. Where I used to go through several paper towels as I blotted the grease off of food, I needed nothing more than the bacon sponge laid across my cutting board to do the trick this time. It sopped up the bacon grease like a charm. After a few minutes soaking in Dawn dish detergent, I threw it into the wash with my towels. Came out lovely — fresh and ready for another round. I do plan on trying it with other foods like chicken. A top-notch product!" —dvitola

    Get it from Amazon for $14.99 or from Green City Living on Etsy for $14.99

    7. Dishwasher cleaning tablets because (to my shock and horror) you have to clean the thing that cleans your dishes and these tablets make giving your machine a deep internal clean as easy as...well...running the dishwasher.

    amazon.com

    Promising review: "I used this to clean my new rental, and to clean the old one. I did use them twice on both over the course of a few days due to build up on the inside. It worked like a charm. I am a big believer in leaving my apartment cleaner than I found it, and this definitely did. My dishes have come out cleaner, and without any residue. Note that I did use two tablets each time I ran it through. I'm excited to try the other products in this line since the dishwasher tablets did so well." —Tom Steude

    8. An easy-to-use collagen-coating hair mask you can apply at home to make it look like your hair hasn't undergone years of abuse at the hands of bleach and blow-dryers.

    10. A patented pet hair remover if the amount of adhesive rollers you're going through is getting out of hand. This roller uses bristles, not sticky tape, to catch lint, meaning you can clean and reuse it over and over and over again.

    amazon.com

    Because it doesn't rely on adhesive paper, you only have to buy it once and can reuse it — cleaning the hair off the brush when it gets clogged, of course!

    Promising reviews: "This is amazing!!! I can't say enough good about it. Works awesome on short dog hair. Cleaned the underside of my comforter where my little rat terrier/chihuahua mix sleeps every night like a charm. I would recommend this wholeheartedly. It is not a sticky thing. It is a brush with little tiny bristles that picks all the hair off the material and then you empty out the chamber where the dog hair collects. I love it! I wish I had found it a long time ago." —Laurie Horn

    Get one from Amazon for $26.95.

    11. A pack of washing machine tablets for complete confidence that the hand-me-down washer that cleans your clothes is actually clean — with no scrubbing required! Just pop a tablet inside your empty washer and run through a cycle like normal for a shiny, deodorized washer drum.

    amazon.com, amazon.com

    Promising review: "LOVED this. It worked like a charm. My washer smelled so gross for some reason. I was desperate and read all the great reviews and it says to keep repeating it like 3x if it stinks really bad, but I only had to do it once. Now I just need to clean the drum. I will recommend this to my mom. She is having same problem." —Alece Louviere

    Get a pack of three from Amazon for $6.99 (also available in a pack of five or six).

    12. A compact knife sharpener that makes it super easy to maintain your blades so you can effortlessly slice through sweet potatoes without any unsafe sawing.

    This teeny-tiny knife sharpener features two slots with carbide blades on one side to provide quick edge setting capabilities, and ceramic rods on the other for the final edge honing. Plus, there is a nonslip base for added stability and control.

    Promising review: "Well I’ve been looking at some expensive knife sets because all mine were dull, Somehow I came across this and I read the reviews so I bought it. It works like a charm, just a few strokes on this sharpener and it’s better than brand new! All my knives are sharp again and I’m slicing paper-thin onions like magic. Needless to say, I won’t be spending the money on new knives." —Jessica fleming

    Get it from Amazon for $11.10.

    13. A pack of multipurpose dermaplaning razors because that middle school eyebrow mishap has made face shaving and brow shaping feel like a daunting (and risky) task. These teeny tiny blades safely remove peach fuzz, exfoliate skin, and include a precision cover for worry-free eyebrow maintenance.

    amazon.com, amazon.com

    Promising review: "Took me a little while to figure out the right angle to use this effectively but once I did it worked like a charm. I’ve used it for shaping eyebrows and managing the little bit of blonde peach fuzz I have on my upper lip. I haven’t tried it anywhere else but no bad reactions or pain, and relatively easy to maneuver with a bit of practice." —Kelly G.

    Get a three-pack from Amazon for $4.99 (also available in a pack of nine).

    14. A pack of bottle-cleaning tablets to remove stubborn stains from the walls of metal tumblers and impossible-to-clean water bottles with NO scrubbing required!

    amazon.com

    Promising review: "I bought these because my husband bought a water bottle with such a small opening I couldn't wash it. It cleans it and does so much more. I've used it on my stainless steel tumbler that I drink tea from. It removes tea and coffee stains like a charm! Makes the bottles look brand new. I just wish the package came with more tablets. I feel like I have to use them sparingly due to the price." —Taylor B.

    Get a 12-pack from Amazon for $8.

    15. A stainless-steel foot file so you treat your feet on the regular and scrape off all that dried, cracked skin keeping you from being the foot model you were always born to be.

    Promising review: "This file is the most amazing product. You name it, I’ve tried it. I’m 80 years old and have calluses on my left foot and heels. This little guy worked like a charm. In 10 minutes both feet were done and smooth. My feet were dry, not wet, and I was careful not to press down. I can’t say enough about the Rikans Foot File." —Arlene R. Bridgeman

    Get it from Amazon for $9.95.

    16. A concentrated allergen spray if you're looking for a quick and easy way to reduce the presence of airborne and surface allergens from pets, mites, and more. Just combine with water and spray those pesky sneezes away!

    Promising review: "I am honestly and simply amazed by this product. It lived up to all it promoted. The true test was a long visit from my daughter who is highly allergic to my cat. Typically the visits are cut short due to constant sneezing or drowsiness from allergy medication. I’m sooo pleased to say she spent hours at my house Christmas Eve and never sneezed once. I spray often and especially before her arrival. Works like a charm!" —Di

    Get it from Amazon for $19.99.

    17. A pair of copper-infused compression sleeves for arch support that won't limit your range of motion. They can be worn directly over your skin — just like socks — and reviewers say they help relieve heel and arch pain caused by a range of issues from bunions to plantar fasciitis.
