Definitions
- the present invention relates to ultrasonic cleaning, particularly to an ultrasonic cleaning method employing a cleaning composition, and to a cleaning composition for use in such an ultrasonic cleaning method.
- a cleaning method may be employed wherein a special treatment is applied to the affected part. This may comprise a stand-alone treatment or a pre-treatment employed prior to employing a regular cleaning method. For example, if part of an article of clothing becomes stained a stain removal product may be applied to the stained part as a pre-treatment. The stain removal product may be applied by being rubbed into the clothing. An absorbent cloth may then be applied to the treated part to draw the stain out of the clothing. After the pre- treatment the clothing may then be washed in a conventional manner.
- a method of cleaning an inanimate article in which method a cleaning composition in liquid form is put in contact with the article, the cleaning composition comprising a peroxygen compound of solid form made part of the cleaning composition shortly prior to the commencement of the method; wherein while the cleaning composition in is contact with the article ultrasonic energy is applied to the article.
- the peroxygen compound of solid form is preferably soluble in the cleaning composition.
- Suitable as a peroxygen compound is any compound which under the conditions used for the method of the invention breaks down to yield an active oxygen species. It is presumed that this occurs via hydrogen peroxide formation (although the mechanism of action is not of significance to this specification or in the utilisation of this invention) .
- Suitable peroxygen compounds include salts, preferably metal salts, especially alkali metal salts, and most preferably sodium salts.
- Suitable salts are inorganic salts. Examples include persulphates and persulfonates . Preferred examples include percarbonates and perborates.
- a suitable percarbonate may preferably comprise an alkali metal percarbonate, for example sodium percarbonate .
- a suitable perborate may preferably comprise an alkali metal perborate, for example sodium perborate.
- the ultrasonic energy is supplied by an ultrasonic device.
- the ultrasonic device may be portable.
- a suitable ultrasonic device comprises a hand held ultrasonic transmitter.
