You can get a gallon of it for about $17 through Amazon. That should last you for years.
That is because it is a penetrating oil and water displacement agent. It was originally developed for protecting the outer skin and the fuel tanks of the Atlas missile.
A gallon through Amazon should be less than $20. I really hate going to Home Depot. The gallons are a much better deal than quarts.
Good advice, wiping your shoes also helps keep unnecessary dirt out of the house. One of our critters is a very sweet, personable and affectionate donkey. Every opportunity she gets to come in the house, she sneaks in, she doesn't ever cause a problem, other than the dirt that comes in on her hooves.
