External pebble dash

[NewhouseOldhouse]

Hi

What's the best product for cleaning pebble dash that doesn't harm pvc window frames?

Also, can this product be used on the roof tiles as well?

Thanks

Low pressure warm water with an appropriate detergent. Higher pressure can be used on roof tiles, but in each case the condition of the render/tiles is important if damage is not to be caused.
