How do you remove dog urine stains from tile grout?

Answer 1

I will make a list of everything on the internet that everyone CLAIMS to have worked for them and /or eliminated the problems.

1) A White Vinegar baking soda paste I made.

2) Plain White Vinegar

3) CLR

4) Zep grout cleaner

5) Soft Scrub

6) "Professional" enzyme grout cleaner

7) Hydrogen Peroxide

8) Hydrogen Peroxide and baking soda paste I made.

9) Miracle Acidic Cleaner

10) Natures Miracle pet odor and stain remover/cleaner

11) OxiClean

12) Tilex

13) Bleach and water mixture

14) PURE Bleach

I could go on and on but let me just put ANYONE who is desperate to solve this issue out of their MISERY and tell you what works.

AJAX power cleanser and a grout scrub brush .......most probably refer to it as (comet cleanser) BUT dont be fooled by that green can your Mom and Grandmoms and Moms before them all used ........AJAX has something in it called "OXYGEN BLEACH POWDER" which Comet cleanser DOES NOT ! Therfore it doesnt solve the odor of the stains.

I'm not sure there is any room for improvement of the research she has put into this answer.

My only comment would be, if the grout joints were sealed to waterproof them to begin with there would be no absorption of urine into them to begin with, hence no bacteria growth and no smell.

I often see, after what is deemed a thorough cleaning, we will apply StableCrete and see contaminates within the gel-pore/capilarry system being expelled up and out to the surface. Then they are removed and another application of StableCrete will penetrate even deeper and in most cases waterproof the grout and solve the problem forever.

Best to apply and waterproof before any contaminates are allowed into the concrete/grout gel-pore system, otherwise you'll be trying one of these fixes when the smell becomes bad enough.
