ABSTRACT:
FIELD OF THE INVENTION
THIS INVENTION relates to a cleaning composition. It relates particularly to a cleaning composition for cleaning metal articles. It also relates to a cleaning solution including the cleaning composition.
SUMMARY OF THE INVENTION
According to a first aspect of the invention there is provided a cleaning composition that can be dissolved in water to form a cleaning solution for cleaning metal articles, the cleaning composition comprising, in combination,
an effective amount of tartaric acid; and
an effective amount of a water soluble cleaning agent.
The cleaning agent may be a surfactant.
The cleaning agent may be in the form of soap.
The cleaning agent may be sodium lauryl sulphate.
The cleaning composition may include citric acid in an amount effective particularly for cleaning brass articles.
The cleaning composition may include iodine in an amount effective for providing a metal article cleaned by the cleaning composition with a shiny surface coating.
The cleaning composition may include 5% to 15% (m/m) iodine, 55% to 75% (m/m) tartaric acid, 3% to 10% (m/m) sodium lauryl sulphate and 10% to 30% (m/m) citric acid.
More specifically, the cleaning composition may include 10% (m/m) iodine, 65% (m/m) tartaric acid, 5% (m/m) sodium lauryl sulphate and 20% (m/m) citric acid.
The cleaning composition may be provided in the form of a dry powder.
According to a second aspect of the invention there is provided a cleaning solution for cleaning metal articles, comprising water having a cleaning composition including an effective amount of tartaric acid and an effective amount of a cleaning agent, dissolved therein.
The cleaning agent may be a surfactant.
The cleaning agent may be in the form of soap.
The cleaning agent may be sodium lauryl sulphate.
The cleaning composition may include citric acid in an amount effective particularly for cleaning articles having a brass surface to be cleaned.
The cleaning solution may include iodine in an amount effective for providing a metal article cleaned by the cleaning solution with a shiny surface coating.
The cleaning composition may include 5% to 15% (m/m) iodine, 55% to 75% tartaric acid, 3% to 10% (m/m) sodium lauryl sulphate and 10% to 30% (m/m) citric acid. More specifically, the cleaning composition may include 10% (m/m) iodine, 65% (m/m) tartaric acid, 5% (m/m) sodium lauryl sulphate and 20% (m/m) citric acid.
The cleaning solution may comprise 20 grams of the cleaning composition dissolved in one litre of water.
