DOOR TO DOOR SALES MEN SOLD ME A PRODUCT THAT DOESN'T WORK AS SHOWN. THEY HAVE HIGHLY CONCENTRATED SOLUTION IN THEIR DEMO BOTTLE. WHEN THEY SPRAYED THE SOLUTION DIRT WOULD SPRAY OFF THE SURFACE OF WHATEVER THEY WERE CLEANING. IT DOESN'T WORK THAT WAY BE MIXED CORRECTLY OR EVEN WHEN DOUBLED. THE SOLUTION IS SAID TO BE NON TOXIC YET IT SAYS IF SWALLOWED TO SEEK MEDICAL ATTENTION IMMEDIATELY AND DRINK 2 GLASSES OF WATER. WHEN POURING OUT OF THE BOTTLE IT SPILLS EVERYWHERE AND EVEN AFTER WASHING MY HAND SEVERAL TIMES IT BURNS MY SKIN.
