Not great...

I was disappointed that the lichen hasn't gone after a few weeks now. There's been light rain and wind, which you say will speed the process up, but it hasn't. I've used sodium hypochlorite before and the lichen went with days, and after some rain, it just kept getting better and better. I thought I'd give this a go as it doesn't contain bleach, but wished I'd bought some more sodium hypochlorite instead.

Hi Steve,

I'm sorry to hear you're disappointed with the results so far. A few weeks to clear Lichen is simply not long enough.

Wet & Forget works quite differently to sodium hypochlorite-based products. It uses a gentle, non-bleach formula that works gradually with the weather to break down growth over time. While sodium hypochlorite gives fast visual results, it typically does so by bleaching the surface, whereas our product removes the growth at the root, which better prevents regrowth.

Lichen, in particular, is one of the most stubborn organisms to remove and can take several weeks to a few months to show clear improvement. Light rain and wind do help, but patience is key with our formula—it continues working long after application.

If you'd like further advice, get in touch with us at sales@wetandforget.co.uk.

Kind regards,

Didn’t work

Unfortunately the product made no impact on clearing the lichen on our patio. Very disappointing given all the promises made for this product.
