A mixed success 50/50 on the same paving slabs in my back garden, some come up great others not so good. Using the same dilution, each area spayed twice.
A bit disappointing.

Hi Colin,

Wet & Forget works gradually, and some types of contamination can take longer to break down than others (even though they may look the same colour). That said, with a bit of patience—especially after a second application—you should start to see results soon.

If you’re not satisfied or have any concerns, please don’t hesitate to contact us at sales@wetandforget.co.uk and we’ll be happy to help.

Kind regards,
James

Disappointing

I’ve just used this, how long does it take to work because my flags don’t look any different 😬😬

Hi Mandy,

Wet & Forget works gradually, and if you've just used it, then you won't see results just yet. Please refer to the reverse of the bottle when using Wet & Forget.

If you’re not satisfied or have any concerns, please don’t hesitate to contact us at sales@wetandforget.co.uk and we’ll be happy to help.
