These clever sponges allow winemakers to mechanically clean wine hoses and stainless steel transfer lines.
Pig Hose Sponges are perfect for hose cleaning and the procedure is extremely simple. Compress one or two sponge rubber balls into the hose and push the balls through with water pressure. Then, repeat as necessary. Strong cleaning solutions appear to have very little effect on the sponge rubber material. You can expect the balls to be very durable and reusable for a relatively long period of time.
