There are several effective ways to clean paving slabs. It’s important to pick a method that suits you and your paving material.
Whatever method you use, start by removing all weeds and loose debris from your paving. Then, if you have a pressure washer, you can simply use this to clean away any dirt.
If you don’t have a pressure washer, you can try using soapy water or watered-down bleach. If you use soapy water, mix a mild detergent like washing up liquid with warm water. Then pour it onto your paving, work it in with a brush and rinse it off with clean water.
If you use bleach, first make sure that the water won’t drain off onto any plant life, as this can kill it. You should also avoid using bleach on concrete slabs, as it will cause them to fade. Mix one-part bleach with five-parts water, pour it onto your paving and work it in with a brush. Then leave it for 15 minutes and rinse it off with clean water.
