Safety tiles in the kitchen area are always a bit of a challenge when it comes to cleaning. Especially when they become really grey and dirty over time due to kitchen use. This was also the case in one of the Betheda social welfare organisation's buildings: the floor was no longer really clean due to all the activity in the kitchen. Our colleague therefore carried out a deep clean on site using Erol G 490 and Erolcid G 491. The result is clear: the dirt and greying have been removed and the tiles shine again.
