no silly, car wash sponges have chemical cleaners, and waxes, in them not intended for DOGS, and Uncle Norms Pet Sponge has ingredients like shampoos and conditioners just for animals...so I dont think they are interchangeable, unles you want you dog to have a nice clear coat shine.....lol
and want you car to to be detangled, and free from flees...
2-X lol
gotta LOVE some people
God bless ya
