Abstract
The present invention relates to a method for polishing hard surfaces. The method includes applying a composition including an alkoxylate to a hard surface to be polished.
Description
- The present invention relates to a method for polishing a hard surface. The method includes applying a composition including a glycol and/or alkoxylate to a hard surface to be polished.
- Metal surfaces have long required polishing, in particular, in the food service and health care industry. Recently, more and more home kitchen appliances have begun to use stainless steel as a facing. Unfortunately, the stainless steel readily shows grease smudges, fingerprints, etc. and requires polishing to restore its shine.
- Current polishes include oil, such as mineral, vegetable, or silicon oil as the polishing agent. Such polishes have several disadvantages. For instance, any overspray of the polish onto the floor presents a slip hazard due to the oil polishing agent. Also, due to the low water solubility of the oil, any clean up of the polish is difficult. In addition, mineral and silicon oils are undesirable on surfaces that may come in contact with food, such as steel sinks in restaurants. Vegetable oils oxidize on a metal surface causing the metal surface to darken over time.
- There remains need for a method for polishing that does not employ an oil based polish.
- The present invention relates to a method for polishing a hard surface. The method includes applying a composition including a glycol and/or alkoxylate to a hard surface to be polished.
- In an embodiment, the method of polishing a hard surface includes applying a composition including a glycol and/or alkoxylate and a source of alkalinity.
- In an embodiment, the method of polishing a hard surface includes applying a composition including an glycol and/or alkoxylate, a wetting agent, a source of alkalinity, and a sequestrant.
- In another embodiment, the glycol is represented by Formula I: HO(R—CHCH2O)nH, where R is an alkyl group containing 1 to 3 carbon atoms and n is 1 to 10,000.
- In another embodiment, the method of polishing a hard surface includes applying a composition including an ethoxylate propoxylate.
- In another embodiment, the method of polishing includes removing soil.

- Various solutions of propylene glycol in water were prepared and tested as a polish on a stainless steel door of a dishwasher. The concentration had an impact on performance in terms of overall gloss and whether or not streaking occurs. For instance, the 30% by weight propylene glycol had slight streaking and good gloss behavior. Good gloss behavior means an individual can discern 15 point letters in a reflection that is 6 inches from the hard surface, but the reflection is not crisp or well defined. The 50% by weight propylene glycol had no streaking and excellent gloss behavior. Excellent gloss behavior means an individual can discern 15 point letters in a reflection that is 6 inches from the hard surface, and the reflection has crisp edges and is well defined.

*poor gloss = cannot discern individual letters of a 15 point print word in reflection from 6″
