	Heavy to Extreme Contamination: Full Treatment Once the contamination has been identified the carpet is pulled back and the contaminated pad is removed. A good trick for making sure the replacement pad is the same size as the pad they are removing is to place the new pad over the old pad and cut through both of them at the same time. A few moments of contact isn't going to contaminate anything and it will save your cleaners time and effort (the real commodity they are selling) when installing the new pad. Once the carpet has been pulled back and the pad removed the sub-floor needs to be sealed (if contaminated). Odor Barrier will cover up to 400 square feet per gallon. The formulation was changed several years ago from a solvent based product to a water cleanup product. Some of you may remember using Odor Barrier on the carpet backing. With the OSR technology the back of the carpet does not need to be sealed.





						Odor Barrier should be run through a paint filter as it is poured into your pump up sprayer. The product may develop clumps during storage and transportation. This is a normal occurrence for the product. As we've stated before, once the Odor Barrier dries it is no longer water soluble. If you spill the Odor Barrier and it is allowed to dry, a high pH substance like household ammonia is required to remove it.



				You can create a temporary "bath" for the carpet by using 6 millimeter plastic sheeting and masking tape. You don't necessarily have to wait for the Odor Barrier to dry before putting the plastic down, the plastic will actually bond with the Odor Barrier and can stay in place permanently. Be sure to overlap the uncontaminated pad by at least 6 inches to keep the good pad from getting wet. Once you have set up your bath you can put the carpet back over the plastic (not re-install just lay the carpet inside the "bath" you have set up) and prepare the OSR solution for the treatment.



		On mixing the OSR (Odor and Stain Remover) there are several variables that may affect the way it reacts: 1. Water temperature. The water should be as hot as possible to make the OSR dissolve completely and react aggressively. 2. Truck-mount concentrate tank. Many cleaners will get their hot water from their truck-mounts, which means that unless they turn their chemical feed off the product in their concentrate tank will be introduced into the OSR mixture. If they are running an acid rinse (like Last Step) it can actually have a negative impact on the OSR solution.

Many cleaners have reported a variation in the amount of foam produced by the OSR while it is being mixed. This doesn't necessarily mean there is a problem with the product. More often than not the water isn't as hot as the cleaner thinks or the OSR hasn't been dissolved completely. In other cases hard or soft water has been responsible for the variation in the amount of foam produced. The bottom line is that excessive foam or the lack thereof isn't necessarily an indication of the products effectiveness.




		Many times I've been asked the question: "How do I know if I need to treat the area twice?" The answer is that some residual odors will fade as the carpet dries because as long as the carpet is wet with the OSR solution the OSR is still active and experience with the product will help determine whether a second application is necessary.



			Afterwards: Some post-treatment instructions will often save a lot of confusion. 1. The carpet may feel a bit stiff after it dries. A thorough dry vacuuming will remove this stiffness. 2. The carpet appears to be lighter where it was treated with the OSR. This indicates that not enough solution was removed from the fibers and an OSR residue is present. A light rinse with either clear water or an acid rinse will correct this.


	After the OSR is mixed (foaming or not) you will apply it to the carpet. Average coverage for the OSR in this situation (no pad under the carpet) is 5 square feet per gallon of ready to use OSR. After applying the OSR you will want to use your wand like a squeegee (no vacuum or solution) to move the OSR around and ensure proper coverage with the product. Once that's done, let the OSR dwell for 30 minutes and then dry extract (no solution just dry vacuum the carpet front and back). If the contamination was severe you may need to extract and repeat the treatment.



			Once the odors are gone dry extract (no solution just dry vacuum strokes) the carpet front and back to remove as much moisture from the carpet and backing as possible. Then insert your new pad over the plastic sheeting and secure in place with a piece of pad tape. Very gently reinstall the carpet. Remember that the carpet backing is much weaker while it is wet and may be damaged easily during the reinstallation process..
