Slow Release Moss and Mould Remover

A non-chlorine liquid formulated to kill moss, lichen, mildew and slime on roofs, decks, awnings, walls, steps, cobblestones, garden furniture, umbrellas, etc. Safe to use on tarseal drives, synthetic tennis courts and playgrounds.

Very simple to use – Just soak it and leave it.

Because it contains a Quaternary Ammonium Chloride as its main active ingredient Sub 30 offers these advantages over chlorine-based moss killers.

  • Less corrosive and so can be applied to any building without risk of damage.
  • Keeps indefinitely on the shelf without loss of strength.
  • For sometime after application it will reactivate and work again when rained on, and so moss and mould will not regrow as readily.

    Mix 1 part Sub 30 Slow Release Moss and Mould Remover with 3 parts water in a garden sprayer or watering can.

    Spray onto surface to be treated ensuring moss etc. is thoroughly soaked.

    For best results application should be early in the morning with little or no wind present and no chance of rain within 6 hours.

    Growth should brown and die within 2 weeks. Sun, wind and rain will remove dead growth given time but if rapid removal is required, brushing with a broom 2 weeks after application is all that is needed.

    Note: If you are collecting rainwater for domestic and stock use, disconnect your tanks for at least 2 good rains after treatment.


    Sub 30 Slow Release Moss and Mould Remover contains Benzalkonium Chloride at 50 grams per litre and should be kept out of reach of children. Harmful if swallowed. Keep out of reach of children.
