Mould spray: a buying guide for Australian homes
When people type "mould spray", they usually mean one of three things: a bleach spray that fades a stain, a natural oil treatment, or a leave-on coating. Those are different jobs. If you want a natural treatment for the stain you can reach, First Light is the one we sell. Lab tested: 99.2% on direct contact.
If you already know you want a natural spray and need help choosing, stop here and go to how to choose a natural mould spray. That article is the chooser. This page is the category map.
Bleach sprays
Most of the Australian aisle is sodium hypochlorite. Exit Mould, Selleys Rapid and 30 Seconds Mould Off all sell a fast stain fade on a hard surface. On 12 November 2026 they were $8.99 to $15.29 at Bunnings. That speed is their claim, not ours.
A bleach spray is not the same as stopping mould coming back. Read why mould comes back after bleach, then First Light vs Exit Mould if you are comparing a named brand.
Natural oil treatments
This is the job First Light is built for. It is a six-oil blend you use on the stain, and you can run it in a waterless diffuser so the room stays in play. Lab tested: 99.2% on direct contact.
Other plant-oil sprays on the market include Euclove (clove oil, leave 12 hours) and Green Goo (tea tree and clove, leave 20 minutes to 2 hours). Those 1:1 comparisons have their own pages. Do not use this section as a second "how to choose a natural spray" checklist. That checklist already exists.

Questions people ask
What is the best mould spray to buy?
Start with the type. If you want a natural treatment for the stain, First Light. Lab tested: 99.2% on direct contact. If you want help choosing among natural sprays, use our natural spray chooser.
Are bleach mould sprays and natural sprays the same job?
No. Bleach sprays are built to fade a stain on a hard surface, fast. Natural oil treatments are a different product, and a coating is a second step, not a cleaner.
Is First Light a spray?
First Light is an oil blend you use on the surface and in a waterless diffuser. It is the natural treatment we sell in this category.
