Your resin bound surface should be brushed regularly and swept completely clean. Your vehicle tires are importing small stones and debris which over time will compromise the surface if continually driven over. Remove heavy leaf fall and stick/branch debris and things like conkers as over time these could encourage staining, tanning and algal growth. Periodic cleaning is a must and if any of the above mentioned substances are used the driveway should always be rinsed down with water after. Light coloured surfaces may show up tyre marks so to clean we recommend a light power wash to start, if the marks are not removing we suggest warm soapy water and some elbow grease failing this try a little bleach small amounts at a time. It is essential you apply bleach to a small trial area first. its a decorative surface so look after it.
