methods of laundering, cleaning, and bathing using the cleaning agent. ## Claims ### Claim 1 A laundry or household cleaning agent, comprising: a diluent comprising approximately 50% by volume of a soapy composition, said soapy composition being prepared by boiling soap nuts in water for thirty minutes (30 min.), the proportion being from 4 to 16 soap nuts per liter of water, thereafter compressing the mixture to reduce the soap nuts to a pulp, and filtering the composition until it is free of soap nut pulp, said diluent comprising approximately 50% by volume of glycerin; said cleaning agent comprising from 0.02% to 0.32% by volume of each of first, second, third, and fourth essential oils, each of said oils being selected from the group consisting of lemongrass essential oil, geranium essential oil, tea tree essential oil, lavender oil, myrrh oil, and oregano oil; and said cleaning agent comprising from 0.3% to 6.0% by volume of polysorbate 20. ### Claim 2 (depends on 1) The cleaning agent of claim 1, wherein: said soapy composition is prepared with from 6 to 12 soap nuts per liter of water; said cleaning agent comprises from 0.06% to 0.12% by volume of each of said oils; and said cleaning agent comprises from 0.6% to 3.0% by volume of polysorbate 20. ### Claim 3 (depends on 1) The cleaning agent of claim 1, wherein: said soapy composition is prepared with from 8 to 10 soap nuts per liter of water; said cleaning agent comprises from 0.08% to 0.10% by volume of each of said oils; and said cleaning agent comprises from 1.3% to 1.5% by volume of polysorbate 20. ### Claim 4 (depends on 1) The cleaning agent of claim 1, said water being deionized water. ### Claim 5 (depends on 1) The cleaning agent of claim 1, said water being distilled water. ### Claim 6 (depends on 1) The cleaning agent of claim 1, said oils being selected as lemongrass essential oil, geranium essential oil, tea tree essential oil, and lavender oil. ### Claim 7 (depends on 1) The cleaning agent of claim 1, comprising 0.02% to 0.32% by volume of liquid grapefruit seed extract. ### Claim 8 A laundry or household method of cleaning and reducing transfer of unwanted microorganisms, the method including the steps of: providing a cleaning agent, said cleaning agent comprising: a diluent comprising approximately 50% by volume of a soapy composition, said soapy composition being prepared by boiling soap nuts in water for thirty minutes (30 min.), the proportion being from 4 to 16 soap nuts per liter of water, thereafter compressing the mixture to reduce the soap nuts to a pulp, and filtering the composition until it is free of soap nut pulp, said diluent also comprising approximately 50% by volume of glycerin; said cleaning agent comprising from 0.02% to 0.32% by volume of each of first, second, third, and fourth essential oils, each of said oils being selected from the group consisting of lemongrass essential oil, geranium essential oil, tea tree essential oil, lavender oil, myrrh oil, and oregano oil; and said cleaning agent comprising from 0.3% to 6.0% by volume of polysorbate 20. dispensing said cleaning agent in an effective quantity in a cleaning procedure; and performing the cleaning procedure. ### Claim 9 (depends on 6) The method of claim 6, said water being deionized water. ### Claim 10 (depends on 6) The method of claim 6, said water being distilled water. ### Claim 11 (depends on 6) The method of claim 6, wherein said step of dispensing includes a step of adding said cleaning agent in an effective quantity to a load of laundry; and said step of performing includes steps of washing, rinsing, and drying the load of laundry. ### Claim 12 (depends on 6) The cleaning composition of claim 6, comprising a fifth oil, namely, oregano oil, present in a concentration of from 0.08% to 0.10% by volume. ### Claim 13 (depends on 12) The cleaning composition of claim 12, comprising 0.02% to 0.32% by volume of liquid grapefruit seed extract.
