Hose cleaning rubber sponge balls are imported from Germany, and allow winemakers to mechanically
clean wine hoses and stainless steel transfer lines.
The wine hose cleaning 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 t.s.p. 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.
