Let me tell you, these oil absorbent pads have been a game-changer in my garage. The first time I used them was when my lawnmower decided to leak oil all over my workbench. I grabbed one of these gray pads (about the size of a placemat) and watched it suck up the mess like magic.
What surprised me most is how they hold liquid without leaking through. Unlike paper towels that just push oil around, these actually contain it. The multi-layer design works exactly like the reviews said - slow to absorb at first, but once it does, that oil isn't going anywhere.
I've since used them under my leaky car (power steering fluid drama), in the kitchen when olive oil bottles tipped over, and even under my sink during a plumbing emergency. They're not great for wiping - more for containing spills - but for that purpose they're perfect.
The 15x20 size is versatile - big enough to matter but you can easily cut them down. After using about half my pack over several months, I can say they're durable enough to justify the price. Just wish they came in different colors so I could color-code my messes!
