As for Wet and Forget, this highly popular algae and mould remover has gathered more than 27,000 reviews. Shoppers consistently praise how effective and quick the results are when using the patio cleaner.
One glowing review read: “Wet and Forget is honestly one of the best outdoor cleaners I’ve ever used. I applied it to my patio, fencing, and the side of the house where mould and green algae always build up.”
Another commented: “This product is the best on the market and worth the cost. My fences have looked great for years with a treatment every 5 to 7 years or so. Plus unlike high pressure cleaning, it doesn’t remove the pine wood treatment meaning it is clean but not exposed to termite damage.”
A third fan said: “The main advantage is its “spray and walk away” application. There’s no need for scrubbing, pressure washing, or rinsing, which saves significant time and physical effort.”
That said, the patio cleaner didn’t win everyone over. One reviewer noted: “Did not find this sufficiently effective on removing algae from Indian stone flags.”
