A low foaming acid cleaner composition, the composition comprising:
- (a) about 1 to 80 wt % of phosphoric acid;
- (b) about 0.1 to 40 wt % of an organic carboxylic acid;
- (c) about 0.1 to 40 wt % of a solvent comprising a hydrocarbon ether or a hydrocarbon alcohol;
- (d) about 0.1 to 40 wt % of a sequestrant;
- and
- (e) about 0.1 to 40 wt % of an ether amine composition comprising the formula:
- [R.sub.1 --O--R.sub.2 ].sub.n --N[R].sub.3-n
- wherein R is independently --H, --R.sub.1 or --R.sub.2 --NH.sub.2, R.sub.1 is a C.sub.1-24 alkyl group, R.sub.2 is a C.sub.1-6 alkylene group and n is a number of 1 or 2;
- wherein the composition has a pH of less than 5 and can remove either carbohydrate or proteinaceous soil from hard surfaces.
A clean-in-place method of cleaning a beverage manufacturing unit, said method capable of removing carbohydrate and proteinaceous soils, said method comprising the steps of:
- (a) contacting containers and conduits in a beverage manufacturing unit with a cleaning composition comprising:
- (i) about 1 to 40 wt % of phosphoric acid;
- (ii) about 0.01 to 10 wt % of an organic carboxylic acid;
- (iii) about 0.01 to 10 wt % of a solvent comprising a hydrocarbon ether or a hydrocarbon alcohol;
- (iv) about 0.01 to 10 wt % of a phosphonate sequestrant;
- and
- (v) about 0.01 to 10 wt % of an ether amine composition comprising the formula:
- [R.sub.1 --O--R.sub.2 ].sub.n --N[R].sub.3-n
- wherein R is independently --H, --R.sub.1 or --R.sub.2 --NH.sub.2, R.sub.1 is a C.sub.1-24 alkyl group, R.sub.2 is a C.sub.1-6 alkylene group and n is a number of 1 or 2;
- wherein the composition has a pH of less than 5 and is contacted with a manufacturing unit for sufficient period of time to remove carbohydrate or proteinaceous soils;
- and
- (b) removing the composition from the manufacturing unit for the purpose of reinitiating beverage manufacture.
A low foaming acid cleaner composition, the composition comprising:
- (a) about 1 to 80 wt % of food grade acid;
- (b) about 0.1 to 40 wt % of a solvent comprising a hydrocarbon ether or a hydrocarbon alcohol;
- (c) about 0.1 to 40 wt. % of a sequestrant;
- and
- (d) about 0.1 to 40 wt % of an ether amine composition comprising the formula:
- [R.sub.1 --O--R.sub.2 ].sub.n --N[R].sub.3-n
- wherein R is independently --H, --R.sub.1 or --R.sub.2 --NH.sub.2, R.sub.1 is a C.sub.1-24 alkyl group, R.sub.2 is a C.sub.1-6 alkylene group and n is a number of 1 or 2;
- wherein the composition has a pH of less than 6 and can remove either carbohydrate or proteinaceous soil from hard surfaces.
