Abstract

A system and method for cleaning and disinfecting soft surfaces such as carpets, fabrics and the like and for cleaning and disinfecting hard surfaces such as plaster, drywall, concrete, linoleum, counter tops, wood, metal, tile and the like is disclosed. The system and method uses electrolyzed alkaline water produced by an electrolysis process using a standard electrolyte solution of water and an electrolyte, wherein the electrolyte includes sodium chloride (NaCl) at a concentration between about 1% and 50%. In a preferred embodiment about a 20% concentration of sodium chloride is used. The electrolyzed alkaline water produced by this method is effective in cleaning and disinfecting both soft and hard surfaces.

Claims

1. A cleaning and disinfecting system for cleaning and disinfecting carpets, fabrics or hard surfaces comprising:

a) an electrolyzed alkaline water storage tank having a volume of electrolyzed alkaline water contained therein;

b) a regulator located in said electrolyzed alkaline water outlet line for regulating said amount of said electrolyzed alkaline water to said electrolyzed alkaline water outlet line from said electrolyzed alkaline water storage tank;

c) a cleaning wand communicating with said electrolyzed alkaline water outlet line for applying said cleaning solution to carpet, fabric or a hard surface;

d) a waste water tank communicating with said cleaning wand for collecting said cleaning solution from said carpet, fabric or a hard surface; and

e) a vacuum pump which communicates with said waste water tank for collecting said cleaning solution from said carpet, fabric or hard surface and into said waste water tank.

2. The cleaning system of claim 1, further comprising a water pump communicating with said electrolyzed alkaline water outlet line and located between the electrolyzed alkaline storage tank and said cleaning wand for pumping said cleaning solution to said cleaning wand.

3. The cleaning system of claim 2, further comprising a water heater located between said water pump and said cleaning wand for heating said cleaning solution before it is applied to said carpet, fabric or hard surface.

4. The cleaning system of claim 1 wherein the electrolyzed alkaline water comprises an alkaline solution with a pH of about 11.2 to 11.6, an oxidation reduction potential of about 840 to 847⁻

mV, chloride of about 200 ppm and sodium hydroxide (NaOH)) of about 400 ppm.

5. The cleaning system of claim 1, wherein the electrolyzed alkaline water comprises an alkaline solution with a pH of about 11.2 to 11.6, an oxidation reduction potential of about 840 to 847⁻

mV, chloride of about 200 ppm and sodium hydroxide (NaOH) of about 400 ppm, is mixed with from between 3 to 5 parts of tap water in the storage tank.

6. The cleaning system of claim 2 wherein the electrolyzed alkaline water comprises an alkaline solution with a pH of about 11.2 to 11.6, an oxidation reduction potential of about 840 to 847⁻

mV, chloride of about 200 ppm and sodium hydroxide (NaOH) of about 400 ppm.
