Promising review: "These are awesome! The size of the container is large and so was the quantity I received. The wipes are huge and tough, great for scrubbing! I cleaned my whole house with these and they removed stains I haven't been able to get out for a while. I also tried them on my walls and they did not remove the paint. Also, they smell fantastic: no chemical smell whatsoever. These are a great deal on Amazon, and I will be purchasing them again!" —Suze
