For years, maintaining the encaustic tiles on my front path has been a battle against persistent lichen growth, especially in areas shaded by overhanging plants. Despite diligent efforts, traditional methods proved futile.
This spring, however, I tested Wet & Forget Mould, Lichen & Algae Remover, a product recommended by Ideal Home as one of the top patio cleaners. My skepticism stemmed from previous failures with my Kärcher K 4 Power Control Home Pressure Washer, a reputed model that struggled to tackle the stubborn lichen.
To my surprise, Wet & Forget delivered remarkable results, surpassing the efficacy of pressure washers. The process, though not instantaneous, proved highly effective.
Unlike pressure washers, which can damage paving slabs by creating tiny pits that exacerbate lichen, mould, and algae accumulation, Wet & Forget offers a gentler solution. It lifts contaminants rather than forcing them out. Currently available at a reduced price of £25.49 on Amazon, this product can also be found on the Wet & Forget Store.
Application Process
To use Wet & Forget, clear the surface of debris and apply a solution mixed at a ratio of one part Wet & Forget to five parts water. A pressure sprayer, such as the Spear & Jackson model with over 24,000 five-star reviews on Amazon, is ideal for this task, though a mop can also suffice.
The solution leaves a slightly sticky residue that must be allowed to dry undisturbed. Avoid applying it on rainy days and keep pets and foot traffic away. I applied it in the evening to ensure it had adequate time to settle before any potential rain.
Rainfall or water from a hosepipe or watering can eventually washes away the lichen, revealing significant cleaning progress over days and weeks. Although lichen may take months to regrow, a second application in about three months can prevent further buildup. The product is safe for plants as long as it isn’t sprayed directly onto them.
Comparative Performance
In a 2022 test, Wet & Forget was compared with two other patio cleaners. After several weeks, and particularly after three months, Wet & Forget proved superior. The section treated with Wet & Forget was notably cleaner than those treated with the competitors, showing effective long-term results without the need for scrubbing.
Two years later, the Wet & Forget-treated area remains cleaner than other sections, highlighting its lasting effectiveness.
User Reviews
User feedback on Amazon praises Wet & Forget not just for paths and fences but also for tackling moss on home exteriors. One reviewer’s comment particularly resonated: “The pressure spray method is slow and messy. Wet & Forget is a far superior and simpler alternative.”
Overall, Wet & Forget Mould, Lichen & Algae Remover emerges as a highly effective and convenient option for cleaning outdoor surfaces, offering results that traditional pressure washing struggles to achieve.
