Blockblitz Arvostelua 5

Absolute rubbish not effective at all. You are just wasting your money.

I’ve used block blitz for about 4 years first couple of applications you don’t see a lot of difference but please persevere the following year you can definitely tell a difference blocks are cleaner no algae or moss you still get a few weeds in between but nowhere near as much

My first time to use this product and was not happy to see my patio dry to white residue patches all over , looked awful so hosed it down , it dried the same with less residue but still looked awful , hosed down again, less residue each time because I’m washing it off so very disappointed, a waste of time and money, so no you can’t wet and walk away as described you'll be back out there once dry because it’ll looks so bad with the white residue, hope it gives me the option to post a picture

I first thought I had wasted my time and money and the block paving looked terrible. After two weeks I noticed the moss between and on blocks was dead and easily brushed away with a stiff brush. I then used a pressure washer and am really pleased with the transformation. Requires patience, nothing will happen overnight, and also a time when it doesn't rain for 24 hours after use - currently difficult but next application planned within 2/3 weeks.

I first posted this review on the BlockBlitz Danish Trustpilot page, but they said "Our product Block Blitz Eco Cleaner is specialled designed for the danish market." and they asked me to remove it. Strange that they should make two different products, one for home use and one for export using same name and logo, so I've moved it here. It is widely sold on UK Amazon and TV Shopping channels

I my experience this product doesn't work. It's a waste of time and money. There is no sign of any dirt being removed from my patio. I know it says that it can take two or more weeks, but what's the use of that? People need some sign of action within a day or so at the most. In my case (I've tried using it twice now) all it did was to leave unsightly white deposits on the stone which had to be hosed off, leaving the dirt still firmly attached.

Sorry, back to the pressure washer.
