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

Works on even the toughest black mould!
The first time I ever used this product was on a patch of black mould that had appeared behind a bookcase. Having taken everything off the bookcase and then having moved the bookcase, I liberally sprayed this on and then went to the garage - via a cup of tea - to find a bucket and scrubbing brush. By the time I returned to the room some twenty minutes later I was amazed to find all the mould gone with no scrubbing required! Recently, however, I found something nasty lurking behind my bed - a massive and disgusting black mould patch! I have no idea how long it had been growing there, but it must have been quite a while! So how well did this product do? Very well indeed! I've uploaded some pictures so you can see the process. It took a couple of hours to completely get rid of the mould, and probably 7-8 applications of the product. But given the nastiness of the patch I was very pleased with the outcome. I didn't do much scrubbing either - after about the fourth or fifth application I did wipe down the area several times to remove some of the black top layer. Otherwise, the process was spray on, leave to dry, then repeat. I was a bit careful around the electrical socket - so I sprayed the product on to cloth and applied it by hand. All-in-all very pleased and happy with the results. I'd give this 6 stars if I could. Some tips! DO - ventilate the area and for a few hours after. The product has a strong chlorine smell. DO - keep pets and children away from the area. DO - put down and old towel to protect your carpets DO - wear gloves.

Legit the best cleaning product I have used ! It's works like magic ! It just makes all the mould and fungus disappear and gets all the dirt and grime clean . Yet to see the long term performance as this clean is based on sodium hypochloride and is know to do just a temporary fix on mould as it does not fully kill mould . Ease of use - it's basic cleaning, spray the infected areas with this spray and wait for few minutes untill it fades the mould , then wipe the area with a cloth and clean with water. Smell - don't expect it to smell fancy , it's has a bleach scent to it . Value for money - for 500rs I would say it's worth it for the strong moulds , otherwise get the non advance version apple scented as it's few hundred rupees cheaper .

When you have tried everything local and it’s still not working-fall into rabbit holes reading product from anywhere that will work this is the ONLY product I have found that gets the black out of grout lines in the shower and shower stain build up on the shower heads to really look new again! Worth every penny when you waste enough on things that don’t do half the job!
