    Brace yourself — things are about to get frightening (in the best way).

    Promising review: "I have three indoor cats, two of them seniors and they have really started shedding terribly. I own no less than a dozen different pet hair/lint removal gadgets and not ONE of them even approaches the effectiveness of this product. Normally, I time my pet hair removal sessions to right before I shower because I am dripping sweat after half an hour of grueling work. I just removed every trace of pet hair from my sofa in less than five minutes and I didn't even break a sweat. As I stood back and examined my sofa, I did not believe it had actually removed the hair but had probably pushed it around somewhere less visible. I popped the button that opens the hair collection compartment on the roller, and THE HAIR WAS IN THERE. WHAT?!!?! It actually took the hair off of my sofa and put it in the compartment!! Literally, I almost cried. I am considering having guests over into my home again...going out to make some friends right now!" —A.W.

    4. K-Cup cleaning pods when you're ready to tackle the questionable buildup brewing inside your coffee maker. You'll be grossed out after seeing what was in there, but at least it'll be gone for good.

    Promising review: "OK, so these cleaner pods are awesome! I didn't know how gross our Keurig was until today. The big mason jar on the left is when I actually ran the cleaner through plus one rinse cycle. The middle one is another rinse cycle and the last one, on the right, is the last one I did. So yes, I would suggest running two or three rinse cycles instead of the recommended one. But it's still an awesome product for the price! I have a 2.0 and I had no issues." —Mads0421

    Promising reviews: "Saved a ton of money for vet bills. This stuff works fantastic and my cat actually doesn't mind getting the drops. I followed the instructions and they did exactly as they said. After reading the reviews, I was sort of convinced but now I won't get anything else. Totally worth the money." —Debbie M

    Promising review: "I really didn't realize how well it worked until I took the after picture. Then I felt bad that I had not done this before. Let me start by saying, I did not even do this every day. I am bad about starting something and not finishing it, but I did use the two tubes that I purchased. I plan on purchasing two more so I can get my teeth whiter. I would recommend this to anyone who wants to get their teeth whiter." —Sheri Blanchard

    8. mold and mildew remover to resolve one of *the* most annoying issues you'll ever deal with. This stuff will help you defeat stubborn mold around showers, sinks, and tiled areas. Apply it, wait a few hours, and your work is done.

    Promising review: "This stuff is amazing. I live in an older apartment complex and even though I scrub and clean my bathtub every week, the caulk around the edge still managed to grow mold and turn brown/ black. I scrubbed with many different products and it didn't seem to make a difference. I found this product and the transformation is huge. First, it's easy to apply because of the squeeze top. I was able to just really focus on the caulk. Then, because it's a gel, it stayed put and didn't ooze everywhere. It really surprised me on those vertical sides. In the first picture, I already scrubbed my tub and even used some sturdy brushes attached to my power drill. The second half of the picture is after five hours of letting this mold remover soak and just wiping it off." —Rochelle

    Get it from Amazon for $14.99.

    9. A bottle of makeup brush-cleaning shampoo because you need to wash away those impurities residing in your brush bristles immediately. The results might give you goosebumps — in the best way.

    This shampoo is hypoallergenic, cruelty-free, and paraben-free.

    Promising review: "I absolutely LOVE this brush shampoo! I was a little skeptical of how well it would clean my brushes since I'd never tried it before, but after using this I am very pleased with the outcome. It has a faint shampoo scent but nothing too overpowering, and suds like you wouldn't believe. It got all the way down to the base of the brush and gave it a really good cleaning. One of my brushes is made from boar hair (Estée Lauder powder brush) and I was worried it was going to frizz it out and ruin the shape, but it actually improved it after I had previously used baby shampoo. It's very soft and not at all coarse feeling. I also used this shampoo on my Beauty Blender, and it did a great job getting all the foundation out. All in all, I'd rate this product a 10/10!" —Ryan Brooks

    Get it from Amazon for $6.99.

    10. A pack of dishwasher cleaning tablets that'll give your machine a super thorough cleaning while it runs. If you've been pulling out spotty dishes that are far from clean, it might be time to clean the machine itself!

    Promising review: "I rarely post reviews, but this stuff has completely changed our lives. Our dishwasher, utensils, plates, and glasses were covered with dry scale and nothing we tried came close to helping. After using the tablets three times our dishwasher looks like new; our glasses are sparkling like fine china and everything else looks fabulous. Highly recommend, worth every penny, best product BY FAR!!! One great advantage is you can use it with your dishes. Some other products are used to clean the dishwasher but not to clean dishes and glasses. Buy this, you will be blown away!!! It is astounding!" —Jenny

Sometimes I would have to apply balm every hour to find some relief. This product has cured my dry lips after two days of use!!! I have been using this balm for two weeks now. I apply 2–3 times per day." —JSal

    Promising review: "I have a white tile floor and I was pretty sure the grout was white also, but it was hard to tell since it was so dirty. I had tried many different methods to clean the grout, with limited or no success, so I gave this product a whirl, and was very pleased with the results. Essentially, you squeeze the bottle, aiming for the grout lines, but in reality, it's a little hard to control, but eventually finds its way to the recessed grout lines, and then let it sit. I let mine sit for 10 minutes. You then need to use a scrub brush to 'agitate' the solution, and it lifted up an amazing amount of grime. You have to wipe up the dirty solution, which sometimes gets into the grout again, so a second application may be needed depending on how dirty your grout is. I have a 6'x6' tiled area on my bathroom floor, so it's a small area, and ended up using about half of the bottle, so this is fairly expensive, but in my opinion, it's well worth the expense because it's the only thing that's worked." —Joseph Canas
