50-Pk Extra Thick Magic Cleaning Sponges

Works well, holds up well, worth the price, I've used them to clean everything in the kitchen, bathroom, baseboard trim, grease on pots... these things are amazing, and all it takes is water! No harsh chemicals required! They are 10cm x 7cm x 3cm. Two thumbs up. I've found that they hold up pretty well with a little water and minimal wringing and twisting. I've also noticed that they work well without chemicals because chemical cleaners tend to clog the microabrasive pores that do the work of scraping the dirt and crud that you are trying to remove. Overall, they are worth the money. I don't know how eco-friendly or biodegradable they are. Maybe the manufacturer can comment on that. I've also read other sites that recommend keeping them away from pets and children because it can irritate skin if rubbed on it so I guess I would recommend not rubbing it on your skin. It makes sense. I didn't try it because common sense told me not to rub it on my skin before I even read the other websites!
