Old & persistent odors: On carpet, there are three scenarios: (1) the odor source has saturated the carpet but not the pad, (2) the odor source has saturated the carpet and the carpet pad, and (3) the odor source has saturated the carpet, carpet pad and sub floor.
Remember, CLEAN+GREEN needs to come in contact with the odor source to work. Once it has made contact, it will encapsulate the odor source and eliminate the odor.
HINT : When urine is deposited on carpet, it will spread in a wider area underneath. Think of a pyramid; the tip is the surface of the carpet and the base is underneath. So you will have to spray a wider area than just where the urine was deposited.
(1) Use Carpet and spray directly on the affected area of the carpet for 3 to 5 seconds, so that the carpet is wet to the touch (but not soaked). Allow area to dry, and check to see if odor is completely gone. If odor is not completely gone, the spray did not have come in contact with the entire odor source. Reapply the spray to the area that still has an odor, following the directions above.
(2) If there is still an odor present after the second application, it may be that the odor source has saturated the carpet and carpet pad. To get to the odor source, you will need to pull up the carpet and spray CLEAN+GREEN directly on the carpet pad. Also, check the back of the carpet for odor, and if present, spray the back of the carpet. Allow it to dry and check to see if odor is completely gone. If some odor remains apply second application following directions above.
(3) In some cases when odor is severe, the odor source has affected the carpet pad and reached subsurface floor. When carpet pad is severely affected (saturated), we recommend cutting out the affected part of the pad and replacing the carpet padding. Spray the affected concrete subsurface with the product, and allow to dry. If odor is present after drying, apply second application, following directions above. Check for odor after the second application, and if odor is present apply the product again. It is not uncommon for many applications when the odor source has soaked into the concrete.
Note: Concrete is porous, and soaks up liquid . You may need several applications. As CLEAN+GREEN eliminates the odor source on the top layer of the floor, the urine odor source soaked into the deeper layers will rise. Each application gets rid of the old odor source until it is completely gone.
USED ANOTHER PRODUCT BEFORE Clean+Green? If the stain and odor has been treated unsuccessfully with other products, the stain and odor are probably no longer organic and you will need to eliminate the chemicals left behind. To eliminate the remaining chemicals, we recommend that you wet a clean cloth with water and moisten the area. Because the stain and odor has probably been changed, you will need to spray more Clean+Green on the affected spot than you would normally be required to use. Note: In some cases, the stain will set due to the chemicals from previous products and may not come out. However, Clean+Green will still eliminate the odor.
