I. applying the above-described cleaning composition to the soiled surfaces, and
II. after a period of time sufficient to remove the soil, rinsing the surface by spraying with water.
EXAMPLES

(B) 0.5 percent isopropyl alcohol,
(C) 5 percent sodium hypochlorite, and
(D) remainder water.
EXAMPLE 1
(1) A standard low pressure garden pump-up type sprayer was used to apply the composition to the surfaces while dry.
(2) The initial cleaning action was very dramatic and visually lightened and cleaned the wood in approximately ten seconds. But upon close inspection some of the mold, mildew, algae, and dirt stain areas were found to be slightly lighter and cleaner than others. The composition was allowed to soak in for fifteen minutes, and the entire area blended into one clean surface at that point.
(3) The test area was thoroughly rinsed with water sprayed through the nozzle of a standard garden hose hooked to the home's standard city water supply.
(4) No other cleaners, chemicals, objects, or materials of any description were used to brush, scrub, clean or in any way touch the surface.
(5) After approximately four hours of drying time, the surface was cleaned and free of all mold, mildew, algae, and stains.
(6) The black stains and dirt were also removed from the "ANDERSON" window exterior vinyl surface.
(7) A second inspection concluded seven days later found the results to be very satisfactory. Also, no damage to any plants was observed even though absolutely no precautions were taken to protect the plants from the composition.
EXAMPLE 2
(1) A low pressure pump-up garden sprayer was used to apply the composition to a dry test area of the deck.
(2) The initial cleaning action that lightened the wood took place in about ten seconds. The composition was allowed to soak in for fifteen minutes. No other materials of any description to aid or assist the cleaning action were used. The test area was thoroughly rinsed with water sprayed through the nozzle of a standard garden hose hooked to the home's city water system.
(4) The surface was allowed to dry to the touch. (Approximately four hours.)
(5) The test area was inspected and the results were found to be very satisfactory. In addition to the initial lightening of the wood, nearly all of the mold, mildew, and algae had been removed.
EXAMPLE 3
(1) A low pressure pump-up garden sprayer was used to apply the composition to the dry test area of the concrete walkway.
(2) The initial cleaning action that lightened the walkway took place in about ten seconds. The composition was allowed to soak in for fifteen minutes. No other materials of any descriptions were used to aid or assist the cleaning action.
(3) The test area was thoroughly rinsed with water sprayed through the nozzle of a standard garden hose hooked to the home's city water system.
(4) The surface was allowed to dry to the touch. (Approximately four hours.)
(5) The test area was inspected and the results were found to be very satisfactory. In addition to the initial lightening of the concrete, nearly all of the mold, mildew, algae, and stains had been removed.
EXAMPLE 4
(1) A low pressure pump-up garden sprayer was used to apply the composition to the dry test area of the deck lounger.
(2) The initial cleaning action that returned the frame and webbing to its original color took place in about 30 seconds. The composition was allowed to remain for fifteen minutes. No other materials of any description to aid or assist the cleaning action were used. The test area was thoroughly rinsed with water sprayed through the nozzle of a standard garden hose hooked to the home's city water system.
(4) The surface was allowed to dry to the touch. (Approximately thirty minutes.)
(5) The test area (aluminum and fiberglass webbing) was inspected and the results were found to be very satisfactory as nearly all of the mold, mildew, algae, and stains had been removed.
(A) 1.0 percent lauryl betaine,
(B) 0.5 percent isopropyl alcohol,
(C) 3.0 percent sodium hypochlorite with a caustic override of 0.35 and a pH of approximately 11.2,
(D) 95.0 percent water, and
(E) 0.5 percent perfume.
EXAMPLE 5
(1) A low pressure standard pump-up type garden sprayer was used to apply the composition to a large test area while the surface was dry.
(2) The surface started to change to a lighter cleaner look within twenty seconds. However, upon close inspection some spots were found that were not uniformly cleaned so the composition was allowed to remain on the surface for a total of ten minutes. At the end of ten minutes the deck was uniformly clean and nearly all mildew, algae and direct stains had been removed. No other chemicals or cleaning methods were used to brush, scour, rub or agitate the applied composition in any manner.
(3) The house water system and a garden hose equipped with a standard pressure nozzle was used to rinse and wash away the residue. The test area was left to dry for three hours. Inspection of the dried test area of the deck showed that it had been thoroughly cleaned and was visually free of any mildew, algae, and dirt stains.
(4) The deck was inspected several times over a thirty day period and no problems were found whatsoevor. The cleaning job was very satisfactory and there was no damage to the wood, nails or surrounding vegetation.
(5) An inspection was performed about 105 days after the initial application, and no problems were apparent.
EXAMPLE 6
(1) A low pressure standard pump-up type garden sprayer was used to apply the composition to a large test area while the surface was dry.
(2) The surface started to change color and appear cleaner within twenty seconds. Some of the more dense wood fibers reacted slower but the entire surface was visually cleaned in ten minutes. Inspection of the cleaned test area showed that the surface was clear of all visual mildew, algae and stains. No other chemicals or cleaning methods were used to clean the surface.
(3) The house water system and a garden hose equipped with a standard pressure nozzle was used to rinse and wash away the residue. The end result was a dramatically clean looking surface that was visually free of all mildew, algae and stains.
(4) The house was inspected monthly for more than eight months and no adverse effects to the surface or surrounding areas were found.
EXAMPLE 7
(1) A low pressure standard pump-up type garden sprayer was used to apply the composition to a large test area while the surface was dry.
(2) The initial cleaning action was clearly visible in thirty seconds and the cleaning was complete in approximately ten minutes. No other chemicals, scrubbing or any other type of cleaning action was used.
(3) The house water system and a garden hose that was equipped with a standard pressure nozzle was used to rinse the surface and wash away the residue and stains from the concrete test area.
(4) The test area was allowed to dry (two hows) and the results were then inspected. The concrete surface was visually cleaned and free from mildew, algae, tree and dirt stains.
(5) An inspection fourteen days later showed that the surface was still clean and had no damage to the surface or surrounding areas. The area was reinspected several times over a six month period and each time the inspection found the results still to be very satisfactory.
EXAMPLE 8
(1) A low pressure standard pump-up type garden sprayer was used to apply the composition to a large test area while the surface was dry.
