Hydra Scrub and Wash Sponges are very handy for more challenging horse bathing tasks. These high quality, durable sponges have a scrubby layer on one side that is ideal for scrubbing away mud, grass stains, hoof oil stains, and other stubborn dirt. Tough yet gentle to not harm your horse's coat or skin, the scrubby side of the Hydra Scrub & Wash Sponge is approximately 3/8" wide on both sponges.
