Nature's gift to cars. If you've ever sunken your hands into a wet sea sponge, you recognize the plush texture that rivals the softness of lambs wool, the cushiony resiliency, the porous, absorbent nature which makes a natural sea sponge a choice for shampooing any car. They soak up and hold tons of sudsy water, decreasing the amount of times you have to return to your wash bucket for more lather. There's something relaxing about sponging off your car with a natural product, rather than a synthetic man-made tool. 6 Pack.
