I hear ya on the weather the last week or so. Tonight and tomorrow sound like they'll be fun with freezing rain for the morning commute turning to rain or snow for the afternoon commute. Since friday morning, I've made round trips to Joliet (2 times), Bolingbrook, Morris, and Orland Park from my house in Schererville. Because of that, my garage floor is covered in sand, cinders, salt residue and anything else put on the roads in northern Illinois and Indiana. Add in a wife that won't knock the **** off her car before pulling in and it's a mess.
I've found that the easiest thing to do is use a garden hose to rinse as much of the heavy stuff as possible. Then, I use straight Simple Green in a spray bottle to mist the floor and a mop to work it around (rinsing the mop every quarter of the floor). Rinse the floor a couple of times, squeegee and I'm done. My two car garage takes 20-30 minutes depending how much **** there is on it. I desperately need to tackle that project as soon as it's warm enough not to turn my unheated garage into a ice skating rink.
