We have a one car garage that stinks to high heaven. I can't stand it - so much so that I dread going in there. I know part of the problem is ventilation. There are no windows that I could crack to let fresh air in. Currently we use it for storage as it's too small to fit a car in. I know the previous owners had their dogs living there. I've tried scrubbing the floor w/ concrete cleaner but to no avail.

Any recommendations for making it smell better? I'm thinking of painting and sealing the concrete floor - do you think this will help? Thanks!!
