*When removing debris from your field such as leaves and dirt etc…a broom and dustpan usually does the job. *Removing stains from your tiles is unlikely, however if necessary, you may use soap and water. *Snow or ice will not harm these tiles and neither will the UV rays from the sun. *The design of this tile is based on the fact that the sub-surface has been built with a natural slope and drain. The modular system allows for air circulation. *Any debris that falls through the tile will flush through the legs underneath; therefore, when it rains it is self-cleaning to a certain point. You may also use a garden hose or pressure washer to help flush debris. *If you ever need to remove a tile or section to assess or clean the sub-surface, all that is needed is insert a painters 6-1 tool between the seems of the tiles and unsnap the locks. Once you have removed a few tiles most of the floor can be unzipped by hand in large sections.
