Wienerberger clay pavers are resistant to chemicals and harsh cleaning fluids, so are best cleaned using biodegradable detergents. However, we don’t recommend that new paving is cleaned within the first three months.
You can use a pressure washer to clean clay paving, however we would not recommend this on a regular basis. The high pressure can disrupt the paving bed surface and jointing material, which can cause pavers to crack or come loose. Mechanical or high-water pressure cleansing operations will require re-sanding of the joints. We do not recommend that sealants are used on clay paving products, as any dirt or spills can be easily cleaned up. Oil will not penetrate the body of clay pavers, it will sit on the surface until it is washed away.
