How to Use
Urine-Erase® keeps its two treatments separate because each one has a different job. Use them separately, in the correct order.
First
Test a hidden spot first to make sure your carpet colour won't run.
Step 1 
Mix the enzyme from the cap with 2 cups of water and let it sit 15 minutes to activate. It won't fully dissolve. It stays thick and grainy, and that's normal. Stir well right before you pour, because the enzyme settles quickly. Pour all of it on the stain, enzyme and all, so none is left in the cup. Let it soak 8 hours, or overnight.
Step 2
After 8 hours, pour the liquid from the bottle on the stain. Let it dry, then vacuum.
Give Step 1 the full eight hours. Patience pays off!
Why two steps?
Step 1 is fresh when you need it
The dry enzyme stays under the cap until you're ready to use it.Time to reach the problem
Urine can soak below the surface and spread through carpet, padding, mattresses, upholstery and other porous materials. Step 1 needs the full eight hours.Step 2 completes the treatment
The liquid in the bottle follows the eight-hour enzyme treatment to finish the job.Watch the demonstration
