Title: USE OF A UREA-BASED MAINTENANCE PRODUCT FOR UNLOADED INNER SPACES IN MECHANICAL APPLIANCES
Abstract:
The invention relates to the use of a maintenance product for unloaded inner spaces in mechanical appliances, in particular cleaning appliances, which are closed during operation, said maintenance product having a content of urea, electrolytes, complexing agents and surfactants and, where appropriate, other constituents, characterised in that the maintenance product contains (a) 5 to 70 wt% urea, (b) 5 to 70 wt% one or more electrolytes, (c) 0.1 to 35 wt% one or more surfactants, and (d) 0.01 to 40 wt% one or more complexing agents. This use means that the integrated parts in the cleaning appliances are completely freed from dirt and also prevents the development of unpleasant odours.
