Effective easy to use product if used correctly
Used this product before. It is very effective and reasonably easy to use on larger areas although some care is needed when spraying wall tiles. Can cause some streaking if not removed reasonably quickly. Not easy to apply in very small areas or edges of tiles which have been laid to form a pattern and protrude slightly. This product is strong enough to do a perfect job even if removed within a very short time span. It is quite a potent smell so would suggest windows are opened if possible as could possibly affect people with asthma or chest conditions. Having said that my experience is that this product works quite speedily if any mould areas are kept regularly under control. I would recommend ensuring you read any instructions on any of this type of product in order to use correctly and gain maxim effectiveness and irradication.

The magical apple-scented elixir that banishes mould with a smile.
I bought the Astonish Mould & Mildew Blaster Apple Burst because my bathroom tiles were starting to resemble a science experiment gone wrong. I needed something that could handle the mould without turning my home into a chemical warfare zone. This spray is like the fairy godmother of cleaning products. I sprayed it on the affected areas, left it for a few minutes, and when I returned, the mould had vanished. No scrubbing, no elbow grease—just a sparkling clean bathroom and a delightful apple scent that lingered without being overpowering. It's effective on a variety of surfaces, including tiles, grout, silicone sealant, and even uPVC window frames. Plus, it's vegan and cruelty-free, so I can clean with a clear conscience. If you're looking for a budget-friendly, effective, and pleasantly scented mould remover, the Astonish Mould & Mildew Blaster Apple Burst is your new best friend. It's the cleaning equivalent of a magic wand—just spray and watch the mould disappear.

It’s really just bleach in a spray bottle.
It’s really just bleach in a bottle, I found the trigger spray difficult to use, it isn’t a spray effect, it’s a direct flow and drips on your hand whilst in use.

Very effective
This stuff is excellent. We got two bottles to treat our basement which was covered in white mould. We ripped off the wooden panelling and ripped up the carpet which we threw away. Then we washed the mould off as it was super thick with water and sponges. Then we sprayed this stuff onto wooden areas like some furniture and doors under the stairs. It's been a month with this and using a dehumidifier it's sorted and the mould isn't coming back! Also worked on black mould on some walls. I will say it was hard to spray though for someone with weak hands and wrists. Will definitely buy again if the basement floods and gets mouldy again

Virtually no strong smell. And it works.
Like most Astonish product's I have found this to be Top Quality. Did the job very well. Cleared black mould after following the instructions. Major bonus was a minimum of strong chemical smell. Happy to recommend all at a Very reasonable price.
