A method of lubricating a moving surface in the presence of an acidic beverage, the method comprising:
- a) providing a concentrate lubricant composition comprising
- i) a fatty acid;
- ii) a neutralization agent;
- and
- iii) a soluble pH buffer selected from the group consisting of carbonate, bicarbonate, citrate, amine selected from the group consisting of urea and morpholine, and mixtures thereof;
- b) mixing the concentrate with a carrier to form a dilute lubricant composition;
- and
- c) applying the dilute lubricant composition to a moving surface.
