Special dual action horse sponge. The Equi-Wash is an innovative sponge specifically designed for washing horses. It has a special dual-action effect which means that you can be a gentle as you like or have the ability to scrub away more dirty patches. The soft side is waved so that the sponge will get under the hair and allow the shampoo to act better and reach the skin underneath giving a more thorough cleaning effect. The rough side is made from a synthetic material which allows the user to scrub with more effect on tougher spots like heals or hoofs or stubborn stains without damaging the skin or hair. The sponge comes in a vacuum pack but expands when opened and dampened.
