The acidity of the lemon powder and the vinegar powder may be higher or lower based on application and other considerations. These two primary powder ingredients are preferably mixed together at a ratio of about nine (9) parts vinegar powder to one (1) part lemon powder. This admixed composition, in powder form, can be dispensed within the dishwasher, for example, in the bottom of the dish reservoir, or placed in the detergent dispenser provided as part of the dishwashing machine.
Alternatively, the powder can be compressed into a tablet shape, or contained in a water-soluble packaging means, such as a pod or packet or pouch (also known as a sachet), and the dishwashing machine can be operated in a conventional manner, pursuant to the operating instructions or recommendations for use provided by the manufacturer of the dishwashing machine.
The vinegar powder and lemon powder are comprised of a variety of chemical ingredients. Vinegar powder comprises, primarily, acetic acid (HC2H3O2) which is a common component of liquid vinegar. Most over-the-counter vinegar products include about 5% acetic acid and 95% water.
Lemon powder primarily comprises citric acid (H3C6H5O7), which is found in lemons, limes, oranges, and other citrus fruits. Citric Acid constitutes about 8% of the dry weight of a lemon.
When the lemon powder and the vinegar powder are mixed with water in the dishwasher, both acetic acid and citric acid will be formed in a mild state. Both of these mild acids are non-toxic, and both are commonly consumed daily, without harm to a person consuming the acids.
During operation of a dishwashing machine employing a composition of the invention, the action of the water and mild acids provides unexpectedly improved cleansing action for dishes, without adverse consequences to a sewage system or septic tank used in the disposal of waste-water.
The composition of the invention can also be used as a general cleanser for cleaning floors, walls, or household items without damage to the item being cleaned or an item in the vicinity of the item being cleaned.
