Muck Off Moss and Mould Killer
You need a very effective moss killer on a Super 6 Asbestos Roof as you cant water blast it. So its got to be killed and washed away with the rain or a normal hose pressure.
Some moss killers use a bleach like Amonia Chloride (in Wet and forget) of a stronger bleach like Sodium Hypochlorate (a bit like Jiff) or a strong Alkali like Sodium Hydroxide.
Our Muck Off is a bit gentler on an Asbestos roof and its key components are Sodium Citrate and Sodium Metasilicate. Dilute it 8:1 for best results.
