Does exactly what it says!. I was very happy with the results

I was abit skeptic about the claim this product made, but I bought 1 bottle and have just used it this week, and Iam very happy with results, I don't have a pressure washer and it's a great alternative for getting algae and mouldy from stone plus it's not toxic to your plants. I followed the instructions closely, and after 36 hours the patio looks so much better,Read full review

Made no Difference to my driveway. I even used double the suggested amount.

This made no difference to my driveway. I used double the amount shown on second application. My driveway is still covered in Lichen. Was expensive, so I was extremely dissapointed when it didn't show even a minor sign of improvement!Read full review

The product works

I recently moved house and my drive wall was covered in moss/algae stains.
I coated the wall (using a paintbrush) with HG and two/three days later most of the staining had gone.
I shall give it another coat before Summer's out to hopefully keep staining at bay.
I have used quite a few products in the past and, although not perfect, it is the best I've found

Watch the Algae run off as soon as applied.

Purchased this recently to remove algae from white gravel boards on garden fencing. Made a solution as directed and with a scrubbing brush applied on a dry weather day. Some of the algae was running off as applied. Left overnight and gravel boards 'came up' pretty clean generally. Note though, algae was not really bad, and had had similar treatment with same product previously.Read full review

Supremely efficient cleaner for algae and lichens

It cleaned off old red lichen on white rendered walls within 48 hours leaving them totally white again. I have not tried it on wooden surfaces. I am cautious about using it on wood as the last version of this product from HG certainly cleared algae off wooden surfaces but also completely stripped all trace of wood varnish from the surfaces. I have tried many similar products over the years but this is the only one that has worked completely.Read full review

Didn't work on my lichens

The promotional blurb said it tackles lichens so I went ahead and bought 4 bottles to treat paved areas that are covered with hundreds of stubborn little white blotches. After 2 applications 2 weeks apart, and a further wait of several weeks, the white blotches are still there, though most of the other stuff is gone. But they are now weakened enough that scrubbing with bleach will now get rid of them. But that's a lot more effort than I'd wanted! Maybe not all lichens are equal and I have a particularly stubborn strain??Read full review

Great for removing algae from fences

I didn't need it for patio, but my fence had green residue all over it. I used a spray bottle to disperse the solution on the fence and the algae on those spots disappeared after a day! No scrubbing needed. I have a lot of fence panels so I will use a bucket and a sponge to apply it on the other fence panels.Read full review
