Can I Use My Usual Household Cleaning Products?

As you have possibly discovered by now, conventional cleaning products on their own are ineffective long term at urine stain removal from concrete, and sometimes they make urine odors worse by “setting” the urine into the concrete. You might use household cleaning products and think the urine smell has gone, particularly during dry weather, but when moisture gets into your concrete patio, the odor can come back, sometimes more pungent than it was before. This is because the uric acid releases a gas when it comes into contact with moisture, and the gas causes the smell.

Since concrete is porous, it soaks up the urine liquid. When the concrete dries, the uric acid crystals in the urine bond to the concrete. As they are insoluble, they remain attached to the concrete. They will not bind with regular soaps and cleaning products that do not break down the uric acid crystals.

  • You want to save some money. Most gallon-sized enzyme cleaners for pet urine cost between $25-$50. Ion-based cleaners of the same size are more expensive; however, if it takes 2 gallons of enzyme cleaner to get the same job done, the costs end up being similar.
  • You’re fine with the cleaning process taking some extra effort on your part and more time to complete. With enzymes, you have to wait for the biological process of bacteria eating enzymes to work before the odor starts to go away. By it’s nature, you may have to reapply several times for odors to become more thoroughly “eaten” away.
