I'm rural, and wildlife takes shelter on our carport. Raccoons and other wild creatures have fought, mated, and aggravated our indoor cats, with the resulting "marking" odor at my kitchen door being overwhelming, especially on hot Southern days.

Washing brick walls is going to require a pressure washer and completely emptying everything off my carport.

So, while I'd bought the spray for my cattery and for accidents around my house, I tried the spray around my entryway.

The scent is completely eradicated.

I'd give this 10 stars if I could.

It does everything advertised, and then some.

It's not cheap, but I've spent at least 10 times the cost over the years on cleaning products that don't work. Not to mention furniture and bedding that's been ruined in the last decade.
