I bought these pads after hearing someone comment that they "really work." Well, I needed something to really work and help me with my cleaning, so I thought I'd give these a try. I bought a pack of 4 pads. Each pad is white, it is the size of a regular sponge, and it looks like a sponge as well. It is treated with a cleaning solution that is activated when you wet it.
I soaked the sponge, squeezed it to get rid of extra water, and set to work. My first project was the fridge that had dark smudges around the handle area; these were gone almost instantly. Then I had some pen marks on the table to get rid of. The pen marks took some more scrubbing, but they were quickly gone, too - without a trace. These pads "really work" indeed! I tried them on my stove, shower, faucets. They clean everything. Sometimes all it takes is a swipe, other times I have to do some scrubbing, but the result is always sparkling clean.
These sponges wear off as I use them, thinning and eventually reducing to almost nothing. On average, one lasts me 2-4 months, depending on how much I use it.
