Abstract

A multi-purpose surface cleaning solution includes sodium percarbonate having a chemical formula of 2Na2CO3.3H2O2 that may be selectively provided in a range of concentrations, from 0.001% through 99.997%. In an aqueous solution, sodium percarbonate decomposes and yields soda ash [Na2CO3] and hydrogen peroxide [H2O2], with additional decomposition of hydrogen peroxide to water [H2O] and diatomic oxygen [O2]. The combination of soda ash, hydrogen peroxide, and diatomic oxygen chemically weaken and release the bonds of the contaminants from the surface(s) to which the contaminants have become attached.

Claims (7)

1. A method of removing residue and contaminants from an interior of a smoking pipe article, the steps comprising:

closing openings or holes in the article except for one opening or hole;

introducing approximately 0.5 ounces (14 grams by weight) of a surface cleaning solution into the article, the surface cleaning solution comprising sodium percarbonate (2Na 2 CO 3 .3H 2 O 2 ), the sodium percarbonate dissolved in a solvent producing an aqueous solution promoting decomposition of the sodium percarbonate yielding soda ash (Na 2 CO 3 ) and hydrogen peroxide (H 2 O 2 );

adding boiling water inside of the article until the article is filled with the water;

soaking the article for approximately 30 minutes; and

rinsing the article with running water to remove loosened debris or residue.

2. The steps of claim 1 further comprising repeating the steps to remove any remaining contaminant or residue from the article.
