Another success with Buzil: In a Hermes logistics centre, the porcelain stoneware floor was not clean despite several basic cleanings and there was always rapid re-soiling. A test cleaning with Erolcid G 491 proved effective: basic cleaning is now carried out with Erolcid G 491 and maintenance cleaning with O Tens G 500 and O Tens Azid G 501 alternately. The result: the floor is clean and there is no rapid resoiling!
