We've had a lot of rain this last week so the pups have mostly been staying inside and pottying on their pee pads (wouldn't want their little toesies to get damp

). But now
someone has stopped using the pads & is peeing in one spot directly on my stained concrete floor.
I want this stopped PDQ! I usually mop with a mixture of Dawn and warm water. Is this enough to get the smell out of the concrete and make them stop going there, or do I need a special cleaner? What kind?
