Hi Joe,
It's hard to say exactly what may have been the case with this job. I can say that recurring spills can be completely eliminated with using Releasit as a spill treatment. And the appearance of a heavily soiled carpet can be restored to excellent condition if you take your time and avoid over-wetting. Here are the instructions for running the Cimex - if followed carefully you should see good results consistently.
Normal Soil:
Make a wet-pass followed directly by a dry-pass. The wet pass is normally made with the valve held wide open walking at a quick pace. The dry-pass is normally made walking at a slower pace. You can feather out a touch more of solution on the dry pass by tapping the trigger every few steps. You just need to wet out the fiber. More solution is not better. The most that you want to use is just enough to lightly whiten the surface. Keep in mind that the average of 300 sq ft per gallon of rtu solution is the target - up or down slightly from that number is acceptable. The wet-pass / dry-pass process that's outlined above is the most common method of cleaning. At that rate you'll average about 2,000 sq ft per hour.
Heavy Soil:
On a heavily soiled carpet there may be a need to make a couple of extra dry passes. If you’re cleaning trashed carpet, you may want to pre-spray the carpet first. Then make a wet pass followed by 2 or 3 dry passes (again you’re only looking to apply enough solution to see a light whitening on the carpet’s surface on your dry passes). This method will average around 1,000 sq ft per hour. IT SOUNDS LIKE THE JOB YOU DESCRIBED WOULD FALL INTO THIS CATEGORY.
Light Soil:
On lightly soiled carpets you can make a single slow pass as you feather the solution trigger (again you’re only looking to apply enough solution to see a light whitening on the carpet’s surface). This technique can average 3,000 sq ft per hour.
Pre-Spraying
In situations where there's a heavier soil load you can use Releasit as a pre-spray. Avoid using another product to pre-spray, because the foreign chemistry will foul up the crystallization. To pre-spray with Releasit simply follow the mixing directions on the container. Use a coarse tip sprayer. Then run the Cimex like normal following the same procedures listed above. In the case of a heavily soiled carpet that requires pre-spray you will likely need to follow the directions for a heavy soiled carpet above.
Recurring Spill Treatment
1. Avoid wetting the spill stain.
2. Scrub the spot aggressively for a full minute. Do NOT apply any detergent. The only moisture that you're scrubbing with is the moisture in the pads. Keep the carpet as nearly dry as possible. This is an extremely aggressive low moisture cleaning. 3. Have a spray bottle of 50/50 Releasit on hand (1:3 if you're using DS). Spray a few good mists of this mixture onto the spill stain. 4. Run the Cimex over the spot one more time to work the solution of Releasit down into the fiber.
Note: Follow these steps closely. The aggressive low moisture scrubbing combined with the crystallizing polymer in Releasit as well as the fluoro-chemical will prevent most instances of recurring spill stains.
Carefully follow the instructions above and you should be successful. Take your time on more challenging carpets. Follow the directions for scrubbing heavy soiled carpets, and carefully follow the instructions for spill stains. And even the worst carpets can turn out nice.
