Here’s how it works: Simply knead a small piece of the gel into a ball and flatten it against the surface you want to clean. That’s it! Once you pull it away, all the nasties come with it. The stuff is reusable, so keep cleaning away until it turns dark from all the horrors you've been subjecting it to. It even leaves behind a pleasant lemony smell.

Amazon shoppers are seriously obsessed with this gel. Oh, and if you're looking for this gel to keep your car clean, why not throw a trash can into the mix to help driving stay tidy? Maybe this nifty car trash can with a lid — now 33% off.

“I used this to clean out the little holes on my iPhone 13,” began one former skeptic. “Before I used it, people kept telling me they could barely hear me, and the voice-to-text and audio assistant could never understand what I was saying. I used this product for about three to five minutes, and I didn't expect much from it. To my surprise, it cleared up pretty much all the problems I was having.... I can't recommend this product enough. It worked way better than I could ever ask for.”

“This gel seems to do the trick to lift dirt, dust and debris off of my dash, my console and my guitars,” said another five-star fan. “It does a great job and doesn't seem to leave any residue for the most part. I bought a second one just for guitars. Sometimes I go to the donut shop on the way to work and get an everything bagel, which leaves tons of seeds and whatever else they put on those stinking things, all over my car interior. This goo picks it all up quickly.”

“Like a lot of people, I eat at my desk," shared this animal lover. "Crumbs were getting everywhere. Plus my cat loved to lie on my keyboard if I was using my laptop. It does such a great job of getting fur and crumbs up. So much better than an air can. Must have for all office desks.”
