Can you give me advice on how to thoroughly clean the floors? Ours is showing dust and wear patterns that we cannot get to look clean.

When cleaning our 8mm Strong Rubber Tiles, we recommend cleaning them with a mild soap and water solution with a synthetic mop head. You can vacuum up any large dirt and debris with a brushless vacuum. If you have a vacuum with a brush, just turn the brush option off is you have the ability to or use the hose attachments. The best way to keep any of our rubber flooring products looking great is to use our Rubber Floor Cleaner and Degreaser and our Rubber Floor Finish and Sealer. Since most rubber flooring is mostly black, footprints, dust, and powders will show quite visibly. With our Rubber Floor Finish and Sealer, you will be able to keep those from showing as much. To apply our Rubber Floor Finish and Sealer, you will want to follow the instructions on the bottle. You will only want to use mild soap and water solutions when mopping the floor. When the sealer is ready to be reapplied, you will need to remove the sealer with our Rubber Floor Cleaner and Degreaser and then reapply per the instructions.
