our paving stones in the back garden are very dirty looking. Have cleaned a few times now with a power washer (water only) but it hasn't made much difference. Can anyone advise of a way to get them clean ?
Advice appreciated.
What colour is the dirt? Ie are they a greenish or blackish colour? if so they may need to be treated with a fungicide as this is a type of algae.
You might try using patio magic available from your local DIY or Hardware. Wash off with a brush and warm water. Follow up with a powerwasher a few weeks later. It would be a good idea to treat the paving with a sealer once dry. Kilsaran Paving supply a good sealer.
