They aren't the biggest problems, but they sure are annoying.

The humidifier you know you've gotta clean. Your teeth that seemingly turned yellow overnight. A loose wall outlet that's basically unusable now. Welp, not anymore! We rounded up some everyday problems and their simple solutions thanks to some Amazon must haves you'll want to add to cart ASAP.

THE SOLUTION: Use an impressive foaming drain cleaner that'll pull out some truly disgusting filth from sink, tub, *and* floor drains... and might just have you seeking out filth like John Waters. 

Check out a TikTok of the foaming pink drain cleaner in action. 

Promising review: "Wow! I don't think I've ever been more excited to use a cleaning product before. Who knew you could get so much satisfaction from a drain cleaner. I could probably make an ASMR video and post it, as it is that satisfying! Even though I had to angle this over my sink drain, to avoid the low faucet, it worked perfectly. The foam went down the drain and up through the overflow, bringing lots of black, yucky gunk with it. I have used lots of drain cleaners before, but not one that actually came up through the overflow. I'd never even considered what stuff was in there. It did a great job of cleaning everything out and it left the sink smelling fresh and clean as well." —Amazon Customer 

THE SOLUTION: Pat on some Catrice "Instant Awake" Under Eye Brightener, a quick, easy fix for concealing and brightening your under-eye dark circles because you don't wanna have to do a full face every single day. This "invisible" coverage oft gets compared to the $33 Becca version. 

The color adaptive formula is designed so one of two shades will work on any skin tone. 

Promising review: "Girlies with dark under-eyes, probs like myself, need to have a brightener! I used to spend $40 on Becca. This one is better, in my opinion!! It’s very pigmented and covers a blue hue in the corners of my eyes. It can be worn alone, but I prefer it under my concealer. It blends incredibly well. Very creamy and easy to apply. It will probably last me six months. A little dab goes a long way. It’s extremely buildable, too. I am just so in love. I’m a sucker for saving money, and this purchase just saved me over $30. I will recommend it to all my friends and family. Just BUY it!" —Caitlin Newcomb

Get it from Amazon for $6 (available in two shades). 

THE SOLUTION: Try out a WD-40 pen that can give you all the same greasy benefits of the OG and help you better target the formula to that squeaky bathroom door hinge you hear every morning approximately 11 minutes before your alarm. 

It'll easily slip into your junk drawer and your toolbag AND your purse because guess what...it comes in a three pack!

Promising review: "I love WD-40 products and use them for everything. I spray on shovels to keep dirt or snow from sticking, spray around windows and thresholds to deter bugs, clean Sharpies off wood and walls, and, of course, stop squeaky doors. These small direct-point application pens are great. Keep one in the glove box, my kitchen 'junk' drawer, and the house toolbox." —BBP623

THE SOLUTION: Brush on some Venus Visage Teeth Whitening Pens you simply apply and let sit a minute or two to dry. Buh-bye annoying, sliding strips and coffee stains.

You can use each pen ~20 times and should expect your teeth to lighten 4–8 shades. I'm currently working my way through one of these pens!

Promising review: "I have only used the two original pens that I purchased and can already see an improvement. I am older than 60 and drink coffee daily and red wine weekly." —vicki houska

THE SOLUTION: Mount a simple cat-grooming brush to help your kitty get some rubs when your hands are all tied up with other tasks.

Promising review: "I got this for my three-legged cat because he can't scratch his left side. He'll be trying to scratch and all you see is his little nub going crazy. I found these and he immediately LOVED it! The expression on his face when he first tried it was priceless. The only downside is that it's possible it'll fall off because it was hard for me to get all pieces of tape to stick on a corner at the same time, but I can always buy more double-sided tape so not a big deal to me. The product is for Floyd, not me, and he's happy, so 5 stars." —Pippa Runs

THE SOLUTION: Place a nearly invisible Snug Plug in the loose outlet to create a snug fit for your hair dryer that keeps falling out of the outlet. No need to pay for an electrician to get involved!

Snug Plugs is a small business that specializes in home improvement products. I had THIS very problem (as a renter) in the top socket in my sole bathroom outlet and one of these little things was a perfect, cheap fix!

Promising review: "I saw Snug Plug on TikTok and immediately ordered them. I have outlets at home AND at work that I couldn't keep anything plugged into because they're so loose. Snug Plug quickly and easily solved that problem and now I can finally have a phone charger in my den. Yay! I highly recommend this product." —KSay

THE SOLUTION: Tap on some Laneige Neo Blurring Powder to absorb oil and blur the look of pores when you start to get shiny mid-day. I own this and it WORKS. 

Promising review: "I loved this setting powder, it blurred my pores and blended my makeup so well that even my husband noticed. Wow! I will be buying more before people find it and sell it all out, hehehe." —Charlotte Laim 

THE SOLUTION: Invest in a genius humidifier tank cleaner that can help look after that lil' machine that's saving your skin this season. This cartridge "swims" around the water tank, helping inhibit the growth of buildup for up to 30 days.

Promising review: "Just drop this in your humidifier and it keeps the water pretty darn mildew and mold free. Super easy to use, no smell, and safe. I have already repurchased and given a few to other people as well." —Kristine

THE SOLUTION: Try some Lumify Eye Drops beloved by the masses who've tried other redness-reducing eye drops before. Yes, these are a bit pricier than other versions. But reviewers say it's totally worth it! Oh, and don't forget that it's also made to help relieve dry eyes. (Just because you TOOK a red eye doesn't mean that you have to put up with literal red eyes.) 

Note that eye drops can potentially mask symptoms of eye conditions, so you should talk to your eye doctor about what's right for you. And according to Mayo Clinic, you should avoid redness-reducing drops if you're looking for dry eye relief.

Promising review: "I have a big spot of blood vessels in the inner corner of my left eye. I use the expensive lubricant eye drops for moisture — I've used Visine, Clear Eyes, you name it. No eye drop has made my eyes look this great. Only Lumify! I was soo happy when I looked in the mirror and saw some beauty in my eyes instead of darkness and redness." —Angela Leonard

"Two drops in your eyes and all day, they look perfectly white and healthy. I would definitely buy these again." —Kelley

THE SOLUTION: Invest in some simple little towel clips to keep dishcloths and towels right where you want and need them instead of slipping off the faucet or oven door handle onto the floor. 

Promising review: "The towel kept falling from the handlebar on the dishwasher. I got sick and tired of constantly picking it up from the floor. Saw this clip on Amazon — it is absolutely perfect. The towel stays in place, and I just love it." —Dee
