Painted concrete floors aren't necessarily difficult to clean; the method is similar to those used to clean most floors, but you must use caution when choosing the chemicals and cleaning solutions. Even if your floor has been treated with a sealant, certain chemicals can break the sealant down and damage the floor, but with the right tools and a little bit of elbow grease, you'll have your painted concrete floor looking like new in no time.

Cleaning painted concrete floors requires the same tools you would use to clean most floors.

Step 1

Sweep the floor thoroughly to gather up the bulk of the dust and larger debris. Take extra care at the corners and edges of the floor--where most of the dust tends to settle.

Step 2

Go over the floor with a dust mop to gather any dust you may have left behind in sweeping. Don't worry too much about getting all of it, just get as much as you can so you don't create a layer of mud when you mop.

Step 3

Fill the bucket with warm water and a small amount of mild all-purpose cleaner or dish soap. Avoid using cleaners with ammonia or vinegar as these may damage the sealant on your floor and bleed through to the paint.

Step 4

Dunk the mop head into the solution and wring it out thoroughly. It is important that you don't saturate the floor while mopping--especially if your floor hasn't been sealed. Too much moisture can break the paint down and make it peel.

Step 5

Start mopping in one corner of the room and work on one 4-square-foot section at a time. Dunk the mop back into the solution and wring it out after mopping each section. Repeat until you make your way all around the room.

Step 6

Pour the solution down a drain and rinse the bucket and mop head thoroughly. Fill the bucket with warm water. Dunk the mop in the warm water and wring it out. Start at the same corner of the room and mop the floor in 4-square-foot sections to rinse away any leftover soap. Rinse and wring out the mop after mopping each section.

Step 7

Allow the floor to air-dry. If you want the floor to dry faster, set up box fans in windows or doorways of the room. Set the fans on one side of the room to blow into the room and fans on the other side of the room to blow out, to create a strong cross breeze. Depending on humidity conditions, the floor should dry in about 10 to 15 minutes.
