Coles mould killer is effective and easy to use. It works quickly to remove mould and stains, especially in bathrooms and grout, with minimal scrubbing needed. Good value and does exactly what it’s meant to do.

I used this Ultra Mould Killer from Coles while cleaning our shower last night and it it seemed to do a pretty good job of getting rid of some mould that had developed. It was also very reasonably priced, so I would buy it again.

Laura Ramirez ✓

Very affordable compared to brands like Domestos or White King. • Works well for basic cleaning — toilets, tiles, floors, and mild mold.

Siddhardha Bobba ✓

The best killer to kill moulds. Once advertised as best in Australia also. Never faced any issue with them. But we need masks while using them. The smell maynot be suitable for all

Hathairat Sritawatsuwan ✓

fast to kill the mould. very useful and worth the price

kaki ✓

Kills off mould very well! You just simply spray an area, leave it for 15 minutes and come back to a clean area. You will see exactly where the spray has hit and you can just repeat the process on any spots you missed. Great product.

Daniel Lundie ✓

It works very quickly on surface mould, making quick clean-ups easy and effective. The spray nozzle is a bit leaky, but the formula itself gets the job done without excessive scrubbing

Yu-wen Huang ✓

Sprayed Coles Ultra Mould Killer on my shower grout last weekend after a humid spell, and it zapped the black spots in under 30 seconds—no scrubbing needed. The bleach whiff lingers a bit, but vents it out quick. Kills germs too; worth it for spotless tiles!

Great product for showers and window sills. Not too bad smelling for a bleach.

Great price and better than more expensive brands. It does have a strong bleach smell, but it works and easy to use.

A very good mould killer, I spray and wipe on my outdoors chairs and it comes clean very quickly, it is a toxic smell but not much you can do about that but use outdoors, affordable

Perfect mould cleaner for bathroom and toilet Spray linearly on mould on walls and tiles, leave it for an hour and then rinse and wash with normal water Very effective in all surfaces Just be careful for the pungent smell and irritating feeling

Works great for most common moulds in the bathroom, but won't penetrate silicon to get to mould growing inside.
