Nature's Miracle Stain & Odor Remover. It is safe and natural. It has enzymes to break the urine down. Carpet cleaning companies use a commercial equivalent.

A bleach application will help with any stains.

You should try some of the enzyme based cleaning products that you get at the pet store. Here is a article that should be able to help you.

All of the suggestions above are great, but as I personally went through this, you need to go one step further. You need to seal the concrete as urine is absorbed into the pores of concrete. I had to lacquer the concrete with an oil based lacquer to kill the smell, seal the concrete, and prevent my kitties from reusing the spot. You can then pain over the lacquer. It takes a couple of coats to ensure the seal is thick enough.

Apply 2 coats of "OIL BASED Kilz" . Ventilate as good as you can while doing the job and put a mask on. I have used this method for many years- has never failed !

went through this also. Use any vinegar, pour on, let dry. No urine smell. Works on carpet for dogs also.

There is actually a product out there called Urine-Off. Works well. Do a Google search to find it.

Pure Ayre should work also. www.pureayre.com

Acid etch and pressure wash, then seal it.

Sealing it is a good idea after cleaning it!...It is cost effective and makes sense.

vinegar is a great start. Then washing/vac the area till water is clear. Sealing with Kiltz may hold but it is not designed as a horizontal flooring application. If any moisture vapor pressure should rise thru the slab, it will pop off Kiltz. Sealing should follow.
