‘Zero-effort’ mould-killing patio cleaner that shoppers swear by is 32% off in Amazon sale

Amazon’s Spring Deal Days sale is underway, and there are some superb deals on garden essentials.

Shoppers are raving about a mould and algae remover that’s perfect for patios – and it’s currently reduced from £21.99 to £14.99.

IF your outdoor space is doing that end-of-winter thing where everything looks a bit green, a bit slippery and far too stubborn for a quick hose-down, this is worth a look.

The idea behind Wet&Forget is simple: it’s a “spray and walk away” cleaner designed to tackle outdoor mould, lichen and algae.

You mix it (one part Wet & Forget to five parts water), apply it with a sprayer, and you don’t need to scrub, rinse or jet-wash afterwards.

That’s also why it’s so handy for awkward jobs like textured paving and joints, where pressure washing can be more hassle than it’s worth.

It’s not a one-spray instant makeover, though.

Wet & Forget is designed to work gently over time, with wind and rain helping to shift dead growth as the weeks go by.

If you do want a gadget-led blast first, this Kärcher patio-cleaning gadget is one we’ve seen shoppers rave about.

One UK reviewer said they waited “quite a while” before writing their review, and the “night and day” difference held up, with the cleaner continuing to work long after application.

Another praised the “amazing results with zero effort”, saying their patio, fencing and side of the house looked “like new” after about a week.

That slower approach doesn’t mean it’s weak.

Some people see faster results, depending on the surface and conditions.

One buyer said it “killed green in approximately 3 hours” on patios and walls, and another reported a “24-hour difference” on decking after saturating the area with a stronger mix.

If you’re after instant gratification, that variability is worth keeping in mind.

It also scores points for being less aggressive.

One reviewer, who was worried about nearby grass, said it didn’t smell chemical and seemed less damaging than other products they’d used.

Pair it with the rest of your spring reset, including this plant food to revive your garden after winter.

Amazon’s spring sale is due to wrap up at midnight on Monday, so get your skates on if you want to pick this up at sale price.
