UN 15R removes limescale from coffee machines, steam generators, hot water boilers (HD units), drive-through car washes, and in the toilet area.

Processing
Apply U.N. 15R to the soiled surface. The reaction with the lime is immediately apparent (slight foaming). Then assist cleaning with a sponge or brush. Finally, rinse thoroughly with water.
Caution: Never use concentrated product on chrome-plated parts in the sanitary area. Risk of surface damage.
When used in a circulation system, adapt the cleaning solution to the material.
For example, with stainless steel, U.N. 15R is used in a high concentration. With non-ferrous metals, the water content is increased.
Please determine material compatibility beforehand!

Application concentration:
Use U.N. 15R as a concentrate for heavy soiling.
U.N. 15R for daily sanitary area maintenance cleaning use at a dilution of 1:20 to 1:100.
These details are recommendations; please determine the optimal mixing ratio through practical testing.
