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.

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

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.

Actually really works !
Do not hesitate to order this if you have mould stains on your curtains it is like magic! Spray on leave, come back & it is gone!! You do need to rinse after as it smells very strong of bleach but wow so impressed - this was done on the lining not on curtains so unsure re patterns

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.

Not very good
It hasn’t touched the bits of black mould that were around the bath seal.

Excellent product
This product is brilliant. I had black mould attached to the seal on my window so I saturated some kitchen roll and placed it on the effected areas overnight.The morning after,the black was completely gone.I am so happy with the results!

It's in the name.
Well worthy of its name. As advised I sprayed a reasonable amount (about 10 sprays) to cover all the infected area. & Within minutes you can see the mould just dissapear. It is astonishing!. Within about 20-30mins it should be ready to scrub. I purchased this product specifically as apparently it doesn't leave an awful smell. & I'm glad to say it doesn't at all, initially a slight smell of chlorine which is to be expected & then a clean apple scent is left. Ultimately its Safe, hygienic, leaves a pleasant smell & works rapidly. I would very highly recommend this product.

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!
