Abstract
The present invention relates to the use of a carboxylic-acid-containing cleaning agent for removing stains of vegetable origin and/or for decontaminating surfaces contaminated by plant-protection agents. The agent comprises 20-60 wt. % of an aliphatic C1-C10 carboxylic acid, preferably formic acid, or a mixture of two or more of such aliphatic carboxylic acids which preferably comprises formic acid, at least one surfactant, preferably an anionic surfactant and/or at least one non-ionic surfactant, and water and/or solvent as the remainder. In another aspect, the present invention relates to specific carboxylic-acid-containing cleaning agents for hard surfaces, which agents are particularly suitable for the intended use.
Claims18
A liquid acidic cleaning agent composition for hard surfaces, wherein the cleaning agent composition comprises:
- 20-60 wt. % of formic acid,
- 1-30 wt. % of C12-C18 alkanesulfonate sodium,
- 0.1-5 wt. % of a C13-C30 fatty alcohol ethoxylate having a degree of ethoxylation ranging from EO 3 to 9, and
- water and/or solvent.
A method for the removal of contamination of vegetal origin and/or for the decontamination of contaminated surfaces, the method comprising:
- applying a carboxylic acid containing liquid acidic cleaning agent composition on the contaminated surface;
- and
- at least partially wash off or otherwise remove the cleaning agent from the surface,
- wherein the cleaning agent comprises:
- 20-60 wt. % of formic acid,
- 1-30 wt. % of C12-C18 alkanesulfonate sodium,
- 0.1-5 wt. % of a C13-C30 fatty alcohol ethoxylate having a degree of ethoxylation ranging from EO 3 to 9, and
- water and/or solvent.
