## Description

Polycell Mould Killer Spray 500ml : desertcart.co.uk: Grocery

Review: Incredible spray - Instant impact, destroys all mould, super effective, easy to use, incredible value for money. I always purchase this when needing to remove mould from around the house and the impact is instant.
Review: Works brilliantly but fumes are awful - Works really well and about instantly! Spray on and it doesn’t take much to soak it. It does start to run straight away though so to avoid it running into the paint below either tape up the area first or have a sponge ready to mop up the run off. Once wet just wipe off with a sponge. There did seem to be some paint on the sponge so be prepared to re-paint after if necessary. Also it STINKS!! I actually held my breath and kept running out the room for another lungful. Kept the door closed to avoid the smell going elsewhere and the window open. Did wear goggles too although they immediately steamed up if I tried to breathe anyway as also wearing a mask. Probably overkill on the safety but I prefer my eyes and lungs the way they are :)

## Questions & Answers

**Q: Can it be used on silicon seals on a motorhome**
A: motorhome, you mean like a cabin? it should be safe as long as they are the same type of silicone that is used in bathroom sealing. This stuff just stinks terribly so maybe have to air the place for a long time, i would recommend trying on a tiny spot somewhere not in the line of sight

**Q: Can it be used on living room painted wall?**
A: yes it can, i used it in our bedroom and it worked fine and pain is ok too

**Q: Can this be used on painted wallpaper?**
A: Mm, the instructions say when mould is under wallpaper you have to strip it back then spray. If the mould is just on top I would probably try bleach wipe. You have to saturate the area so you may ruin your wallpaper. Obviously I don't know that you can't, just a guess. Maybe email the manufacturer?

**Q: Is this just for indoor use?  Or can it be used outdoors on garden furniture?**
A: We got it for the bathroom ceiling and it's worked a treat,  can't say about using outdoors,  sorry.

### ⭐⭐⭐⭐⭐ Best I've found to date
*by C***G on 24 December 2022*

Thanks to a poorly ventilated bathroom in our rented flat we've had a long standing mould problem. We were always washing the walls down with bleach. We've tried lots other brands over the years and although they all kill the mould we've always found it comes back quickly This has been a game changer. Not only does it kill the mould, but it leaves a fungicidal residue behind so mould doesn't come back in that place. Some of the places where we were always getting rapid recurrence before haven't had a black spot in over 3 months. I suspect in time it will wear off and need reapplying but it's gone from mould being a major problem all over the room to where we're maybe having to spray a tiny patch once a month (where dark spots are popping up in areas that haven't been treated before) when we first notice it. It's easy to use - spray on, wipe off. We've found in the areas where the paint is peeling that it's worth leaving it to sit for a couple of minutes before wiping, so it has the time to diffuse in to the cracks properly. It is very pungent and you really do need to ventilate the room well when using (so crack all the windows if you have them, or have your extractor fan going for a while), and wear gloves and a mask as well, but to my mind it's absolutely worth it
