How do I clean dog urine smell from my concrete porch?

To be plant safe, I would just scrub with hot soapy water. Dawn or another dish soap or castile soap won't hurt the plants.

Mop with Vinegar and water

You need a strong deodorizer and disinfectant. I use Simple Green for all those needs. It is in Walmart and most home improvement stores.

Thanks for your help ladies!!

Get some bleach & pressure wash it or use muratic acid then pressure wash but wear protective eyewear & clothing. After...seal with Thompson’s Water Seal so it won’t happen again!👍🏼
