The invention consists of the foregoing and also envisages constructions of which the following gives examples.

DESCRIPTION OF THE PREFFERED EMBODIMENTS The present invention comprises a cleaning composition suitable for cleaning a stainless steel 20 surface.

The first cleaning composition comprises cetearyl isononanoate in the form of Cetiol SN mixed together with lemon oil. This may be lemon oil in the form of a range of some of the natural oils of lemon peel, or one or more of the active ingredient. The cleaning composition thus formed is especially effective in removing stains and/or grease and/or smears and/or any 25 contaminants on the surface, particularly when the surface is a metallic shiny one.

In most of the examples we prefer to use D-Limonene which is a yellow oil with a characterislic" lemon taste and odour and even though it is present in a small amount, it serves as a cleaning agent in its own right, and it also acts as an anti smearing agent. It also provides the composition with a fragrance. 1 Q6297NZD_CAP.DOC Received at IPONZ on 22 April 2008 Even though this cleaning composition contains lemon oil in the range of 1 and 10% w/w, it was found that about 2% w/w of the lemon oil tends to give the most satisfactory results. The formulation is given in Example 1.

The formulation of the second preferred embodiment is given in Example 2 and the reader will 5 see that it includes a glydant composition formed from multiple components in equal weight for weight.

The details of the preservative can be found in Table 3.

Example 1 A preferred formulation for the cleaning composition of the present invention is as follows: 10 substantially 98% w/w of Cetiol SN and substantially 2% w/w of D-Limonene.

Example 2 Another preferred formulation for the cleaning composition of the present invention is as follows: substantially 97.8% w/w of Cetiol SN; substantially 2% w/w of D-Limonene and 70% total w/w (for the glydant and solvent mixture) in any combination of 1,3-Dihydroxymethyl 5,5-15 dimethylhydantoin; l-HydroxymethyI-5,5-dimethyIhydantoin and 5,5-DimethyIhydantoin; whilst 3-Iodo-2-propynl butyl carbamate is 2.5%w/w (of the glydant solvent mixture) and 1,3-butylene glycol is 4.5%w/w (of the glydant solvent mixture), and the formaldehyde is 0.19%w/w (of the glydant solvent mixture) and the water is makes up the remainder of the w/w%.

Example 3 Another preferred formulation for the cleaning composition of the present invention is as follows: substantially 98.5% w/w Cetiol SN and 1.5% w/w perfume in the form of green lemon 4852.

Other examples employed during the research stages included 106297NZD CAP.DOC Received at IPONZ on 22 April 2008 Examole 4 Mineral oil (Finavestan A80B) as substantially 98.5% w/w and 1.5% w/w/ perfume in the form of green lemon 4852.

Example 5 Mineral oil (Finavestan A80B) as substantially 98% w/w and 2% w/w D-Limonene.

The cleaning composition is best prepared by a method which includes the steps of mixing and dissolving D-Limonene in Cetiol SN.

This is performed by placing the Cetiol SN into a clean dry mixing vessel, and adding the D-Limonene drop wise followed by the glydant dissolved in the glydant solvent mixture in a 10 similar manner.

Once the D-limonene and the glydant dissolved in the glydant solvent mixture has been dissolved, the mixture is ready for bottling.

The method of restoring the lustre^to a metal surface that has been contaminated comprises the steps of applying the cleaning wipe to the surface, applying pressure and friction with a rag, 15 tissue or cloth firmly over the surface containing the cleaning composition and subsequently removing the cleaning composition from the surface.

The preferred cleaning wipe of the present invention works particularly well in restoring the lustre of metallic surfaces such as stainless steels and chrome, however either embodiment of the cleaning wipe may also clean other smooth surfaces like porcelain copper, other metals, 20 metal alloys and even fluorinated objects having surfaces that are known commercially by the Registered Trade Mark "Teflon".

Users will also find- the, cleaning wipe effective when applied on the surface of cutlery, sinks, wash hand basins and bathtubs. It should be noted that the cleaning wipe is biodegradable. 106297NZD_CAP.DOC
