 Tips and tricks:

      • You can rake or hard brissle brush the affected area to speed up moss, mould and lichen removal
      • For heavily contaminated areas it may be necessary to re-spray once the initial application has dried
      • Recommended to wear protective gloves and eyewear when using product
      • Do not apply on or around feed, animal feed and any plants planned for human or animal consumption
      • No harmful residue and does not harm earth worms or soil microbes
      • If you are on tank water we recommend disconnecting down pipes, and leaving for 2 or 3 heavy rains before reconnecting to ensure all Spray and Go residue is removed


  • For years I have used another well known moss and mould removal product (on the radio) and one of my friends suggested I  try Spray and Go. I was blown away by how great the results were. It killed the green Moss within 24 hours and I found it worked incredibly well on the black mould. Our concrete has gone back to the original colour. There is no comparison this product is awesome.

  • I tried a product that was supposed to work on the moss on concrete tile roof.  Did not work and when I rang the supplier they did not want to talk to me. I rang Spray and Go and they offered me a great deal and best of all it did the job fast. My full recommendations.

  • Had some Moss covered concrete paths and decks…Spray and Go cleaned it up like new…So easy to use. Top marks Spray and Go, could not believe how fast it works. My full recommendation. It does really work!!!!

  • My McCullum chip driveway went black with mould…I used Spray and Go and within 3 weeks was like new again. Amazing products and I used others that did not work well at all despite what they said.

  • I have been using another well know advertised product for years and 18 months ago changed to Spray and Go. The product worked fast and 12 months later there was still no mould growing…A product everyone should try.. I also used Turbo product and was brilliant!

Jeremy B. Mangere

  • We tried the Spray and Go on our Astra Turf tennis court..It was covered in Moss and Lichen…Spray and Go cleaned it up in a real hurry. Looks like new again… I used a product often advertised on the radio and there was no comparison. Just did not do the job.!!!
