My floors!

I don’t normally think so much about my floors.  My dogs have always made them gross, primarily because our backyard isn’t landscaped, so wet weather makes for muddy feet that wander throughout our house.  We routinely have hand towels by the back door and we wipe eight little paws as the dogs come in again and again.  But it just isn’t enough!  I am sweeping and mopping my floors several times per DAY and it is still gross. Proof? My ‘white’ socks after mopping: blech!  It’s hopeless!
