  2. Apply: Use a pressure, backpack, or commercial sprayer on a dry day to ensure deep penetration.

To safely collect rainwater after applying Spray & Go on a roof, it’s advisable to disconnect your water tank for a minimum of 3–4 weeks, or until at least 36mm of rainfall has occurred. This waiting period ensures that any remaining concentrate and decomposing debris are thoroughly rinsed off before entering the tank.

FAQs

What dilution rate should I use for lawns?

We recommend a 25:1 dilution (25 parts water to 1 part product). Always start with a small patch test before treating a large area.

After using Spray and Go Commercial, I’ve noticed a brown/orange tinge left behind. Is this normal?

Yes, this is completely normal and a sign the product is working. The brown/orange colour appears when the Benzyl Ammonium Chloride kills the algae, releasing pigments from the growth.

The discolouration will gradually fade as the moss and mould break down, and surfaces typically start to lighten within a few days to weeks. There’s no need to use bleach or other cleaners.

Is Spray & Go Moss Mould Remover safe for cedar timber?

Yes, our Moss & Mould Remover can generally be used on cedar timber, but there are a couple of important considerations.

Always test on a small, inconspicuous area first to ensure you're happy with the finish.
Avoid allowing the product to dry on the surface. Apply it as directed and rinse if the label recommends doing so.
If the cedar is oiled, stained or painted, test first, as cleaning products can sometimes affect the finish.
If the timber is weathered or untreated, the cleaner may brighten the surface slightly, making the treated area appear cleaner than the surrounding timber.

  1. I’ve been using Spray and Go Mould and Moss killer for my clients with exceptional results. The first application was to clean moss covered clinker brick. As I sprayed, you could see liquid dropping off the moss. Next visit, I was a little frustrated thinking someone had water blasted the area it was so clean. I was assured it was just the spray.

    On another occasion I had a client that had a thick covering of lichen on their drive. I ran a test strip and after a few weeks the seal was visible. I’ve now done the entire driveway and there is scarcely any lichen visible!!

    My clients love the product and I’m thrilled with the results. I highly recommend it for a long lasting cost effective product that works over a wide range of moss, mould and lichen and a wide range of surfaces.

    Tip:
    At home we had a problem with mould forming around our aluminium joinery, inside. I applied some solution to a sponge and wiped the areas concerned. The moss is gone and has not returned, unlike the results of other moss killers.

Is it safe on painted wall? Jason asked on 30 June 2025

Hi Jason, Yes, Spray & Go Moss Mould Remover Commercial 5L is safe to use on painted walls. It's non-toxic and non-caustic, but we recommend testing on a small area first to ensure compatibility with your specific paint type.

Will the walls etc need to be waterblasted after treatment?

Terry answered on 4 March 2026

Hi Terry, No waterblasting isn’t required. Just spray and leave, the product kills the moss/mould over time, and rain usually washes away the residue.
