Defenders Concentrated Path & Patio Cleaner – 2 Litre, Non-Acid Formulation, Clean Brick, Tarmac, Asphalt, Block Paving, Concrete and Stone

Would buy again

Really good result

Didn’t find the product much use. Will give it another try.

Good value product which worked well .

It’s curious to note for starters that inside the box you will find a two litre container covered with a thin layer of bubble wrap. I’m not entirely sure what that aims to accomplish but I will say that at least it stops the cardboard box from getting soaked by the liquid that leaks out in transit… but alas, your introduction to the product consists of having your hands covered with something that according to the manufacturer is irritating to skin and eyes. Not a great start.As you read the instructions you then come to realise that the “concentrated” formula is to be diluted in one to two parts of water, which means that if you are to use it in its strongest solution you will have a grand total of four litres of patio cleaner to play with so if the area you are planning to clean is slightly bigger than a phone booth, you may want to consider other options.Onto the final result. The manufacturer claims this product kills mould and algae from exterior hard surfaces. Perhaps if you wait long enough mould and algae tire of waiting to be struck down and die of boredom. My patio looks considerably better today than it did before but that is down to a couple of hours of hard graft with a pressure washer and a brush. The only evidence that this product was ever applied consists of a layer of foam considerably less aggressive than Will Smith.

A One Thanks

Not that good better results with washing up liquid

Simple instructions, 2 parts water to one part product. Mix in a watering can then sprinkle over. I think I should have got 2 as it seemed to run out quickly. Reasonable results. Driveway looked cleaner although I think you’d need a stronger product if you had a difficult area to clean. I’m satisfied with the results.
