Our sponge cloth was further developed especially for this application and tested by the Teaching and Research Institute for Cattle Husbandry Hofgut Neumühle, belonging to the state of Rheinland-Pfalz, in Münchweiler an der Alsenz. A practice-relevant long-term investigation took place since 2006 in the dairy sector on approx. 70 dairy cows to analyse practical suitability.
The results can be seen or "read":
After more than 250 machine washes at 60°C, almost no wear can be detected, colour fastness is good, the feel for the user and the udder stimulation are classed as pleasant and very good. In direct comparison to competitors' products, the dirt absorption and cleaning capabilities were more favourably classed; the fact that the Kalle udder cloth is biodegradable was praised as an important and significant contribution to environmental protection compared to other products (disposal as manure/liquid manure).
When cleaning udders, we recommend that the sponge cloths are machine washed before every use at a minimum temperature of 60 °C using standard washing detergent, and then used in a moist state.
