As the bank holiday weekend approaches, many homeowners are preparing to tackle their outdoor spaces. Patios, driveways, and decking often become green with mould, lichen, and algae after the winter months, traditionally requiring a high-powered jet washer for cleaning. However, a popular alternative is gaining attention for its simplicity and effectiveness.
The Wet & Forget Solution
Shoppers are increasingly turning to Wet & Forget Multi-Surface Outdoor Cleaner, which they describe as just as effective as pressure washing but incredibly easy to use—with no scrubbing required. Currently, there is almost a third off a 2-liter tub that covers up to 120 square meters, now priced at £14.99 on Amazon.
Customer Reviews and Ratings
This cleaning solution has earned five stars from more than 17,500 customers, with thousands purchasing it in the past month alone. One satisfied user wrote, "So easy and so much better than a pressure washer. Can't recommend it enough." The product has been bought by over 27,000 Amazon customers, achieving an impressive overall rating of 4.4 stars.
Another customer shared, "I honestly cannot fault it. No weird residue, no strong lingering smell, no damage to surrounding areas. It just quietly works." A further review added, "We have a concrete driveway mostly in the shade all day and yes it is a green petri dish for algae. Used Wet & Forget and hey it's a miracle no more green even 10 months on! Can't recommend this too much."
How to Use Wet & Forget
The application process is straightforward:
- Dilute the solution in a 1:5 ratio with water.
- Apply it to any outdoor surface.
- Allow it to sit for a day or so, depending on the cleaning needed.
- Rinse with a garden hose or let rain wash it away.
The pet-friendly, non-bleach formula is versatile and can be used on various surfaces, including roofs, bricks, stone pavers, concrete, tarmac, artificial grass, and decking. Reports from Teesside Live highlight its broad applicability. One happy customer noted, "Such a great product, easy to use—you just fill with water as per instructions and spray and leave. The end."
