The patches come back

We have gained this carpet cleaner, as our dog puppy made by urinating a lot of spots in the bright carpet. After applying and brush are really neat spots all went out. Only a stubborn stain remained. After the concentrate was simply less diluted and was applied again, and the stain was gone. Although we have a very bright carpet, no edges or the like could be seen after Anwednung.

A few weeks later, however, things are different. All !!! Spots are durchgeschimmert again after a few weeks and are present as before using in de same intensity. After re-administering all patches were gone again until they came through again after 3-4 weeks. Therefore, this product is recommended only very limited.
