Removing very stubborn black lichen from sandstone

Hi,

I’m trying to remove some very stubborn black lichen from an Indian sandstone patio. There are 3 stones (1 in particular - The curved one) where I just cannot get the stuff off. So far I’ve tried… Pressure washing alone. A water based biocide then pressure washing. Sodium hypochlorite and stiff brush. This helped get some light stuff off a few of the lesser affected stones but these 3 remain stubborn.

With the hypochlorite I wet the surface first, applied solution neat, scrubbed with stiff brush. Repeated application and scrubbing every 15 minutes for about an hour. This lightened it slightly on 2 of the stones and the 3rd ever so slightly (maybe).

Various AI’s can’t agree on the best way forward.

Does anyone have a recommendation?

I’d like to get the whole lot sealed before winter kicks in and want to clean this off first if possible.

Thanks.

What big family tents fit on UK campsite pitches?

Hi,

Family of 4 wanting to start camping (4yo & 8yo). Mrs isn’t 100% convinced so I’m trying to make it as comfortable as possible so looking for a big family tent.

I’m new to this but I’m working on the assumptions that even big pitches in the UK are 10m x 10m (bigger than that would be unusual?). 1m clear space is needed around perimeter of the pitch. At least 1m maybe 1.5m is needed for guy ropes on all sides. So being pessimistic the max tent size would be 5m x 5m. That doesn’t seem like a very big tent for 4 people particularly the length.

I was interested in the Berghaus Telstar 8 but that’s 7.5m long. So may / would need a 12.5m long pitch. Even when going down to smaller models the lengths seem to exceed 6m.

Am I missing something?

Thanks.
