Waldo,
If the smell of the Odorcide is really too strong, you may be mixing it too concentrated, to try any counter an incomplete source removal. If you find you have to mix it really strong on urine, you are failing to remove most of the urine through pre-conditioning and cleaning.
One of the most important principles of deodorization is using the deodorizer only on the non-removable residue. This means, your MUST remove the source as completely as possible before you even attempt to introduce the deodorizer. Your effectiveness at removing source material will dictate the strength of deodorizer necessary, which ideally should be minimal.
The most common error in urine decontamination is thoroughly addressing the whole situation. Carpet, Padding AND subfloor/walls. Old urine deposits will not clean effectively with a typical alkaline cleaning agent. You need to introduce a cleaner, specifically designed for urine salt removal and the gummy residue.
Scott is right on though. Hydrocide is often used where the odor of Odorcide is objectionable. But neither should need to be used near maximum concentration on urine.
