Product Description

Product Description

HG mould spray effectively removes all brown stains caused by mould, fungus and algae. These unsightly black or brown marks are found on the silicon seal between the bath tub and edges of tiles, on the shower cubicles and on plaster. HG mould spray is also highly suitable for the removal of coffee or tea stains from plastic worktops. Spray HG mould spray on the surface from a distance of 3 to 5 cm. Repeat the treatment on badly affected areas after 10 minutes. Allow 10 minutes for the product to work and then rinse off with water and a sponge.

Product Description

Removing mould has never been so easy. Tiles, grout, sealer and ceilings can all come under attack from mould but HG's powerful cleaner knocks the spots off other cleaners, destroying it immediately on contact.

  • Makes black spot mould disappear.
  • No scrubbing required.
  • For bathroom and kitchen.
  • Treats UPVC, tiles, grouting, silicone sealers, walls and ceilings, garden pots.

UPVC window frames, gouting and silicone around the bath or kitchen sink are prone to persistent black spot mould, which even bleach can't touch, so the cleaning experts at HG came up with a specially formulated solution that destroys mould immediately on contact. Just spray it on, wait a few minutes and watch it disappear before your eyes!

Damp plastered walls and ceilings in the home can also be treated, and as it's effective on algae, fungus and moss, garden pots, tubs and ornaments will benefit too.

(Not suitable for use on enamel surfaces.)

Carriage Restrictions : Please note this product can be delivered to Mainland UK only (this includes Scottish Highlands & Islands). This product can not be sent to Northern Ireland or the Channel Islands.

5.0 out of 5 stars It really works! 22 Mar 2010
I had terrible mould problems with a shower. The worst bit was the sealant around the shower tray which was mostly that tell-tale orange colour, and black in places. I have spent ages scrubbing with a toothbrush and neat bleach, which worked on the tile grouting, but didn't touch the sealant. I had to give up as I was going to spoil the seal eventually, and was resigned to replacing the sealant, and having to do it again every year or so. Then I read some good reviews for this stuff, and thought I would give it one last go. I am amazed - I have clean, bright, white sealant - and the whole shower looks like it's just been fitted. It was so easy as well - spray on, walk away for 30 minutes, come back, fall over with the shock of getting a brand new shower, pick yourself up and rinse it off. Absolutely no elbow grease whatever. It's now a real pleasure to get in there for the first time ever, as this problem existed when we moved to this house. It also worked wonders on a ceiling where we had a damp problem a while ago - black mould also vanished after leaving it for 30 minutes. 6 weeks later - no sign of it in either place. No doubt it will come back in the shower eventually, but I'm not bothered, because a quick blast with this stuff will shift it before it gets nasty. Yes it is strong stuff - but not so that you feel it's doing you harm. Open the window and walk away for frequent breaks if you have a large area to do like I did. I found it safe to use on the ceiling by standing on a chair and spraying at an angle so that it wasn't directly above me and couldn't possibly drip onto me. It wasn't dripping by the way, but you do need to be careful. Strongly recommended.

5.0 out of 5 stars DIRTY DEEDS! 24 Feb 2013
Verified Purchase
Firstly let me just explain a few things. I am a man. I am a big man with tattoos. I am a big, tattoed heavy metal appreciating Yorkshireman and as such I know I am not supposed to get excited by cleaning products!
I am sorry to say that I have failed in living up to society's stereotypical view of me. This product is AMAZING! Our house has been a victim to patches of black mould and mildew for years and despite numerous attempts to banish them forever I have failed miserably, UNTIL NOW. After spraying it on and leaving for half an hour the results were like magic, it has removed marks from silicon sealant, grout, UPVC window frames, painted plasterboard walls and ceilings, the lot! And what's more, the stains have failed to return as they have so many times before.
I cannot praise this wonderous product enough, if you have issues with mould and mildew, don't hesitate CLICK AND BUY IT NOW YOU WONT REGRET IT.

3.0 out of 5 stars Just watered down bleach?
Not as good as I had hoped. I think it's just bleach and water? I could buy cheap supermarket bleach for a fraction of the price and it would do the same job.
