What do you use to remove mould and moss spores from concrete?

I have just had it pressure washed and there are still black spores evident. Will bluestone get rid of these and will it stain the colour of my court?

Hi Lachlan,

Bluestone is more effective against algae and therefore is not really suitbale for this use. There is a Yates product called Surrender which is excellent for the control of moss on tiled roofs, rockeries, drives and pathways. The active ingredient is benzalkonium chloride which is also used in other industries as a sanitiser for the control of bacterial spores. Surrender should be available from Rural outlets and some hardware stores
