sandstone sills
I have cleaned these before using hypo, and they came up good. but I have some to do that are quite bad ( not the one in the photo )
will a strong mix of hypo and hot water be ok, or will I need something else like pressure wash ?
many thanks

You don't use hot water with hypo
I would pressure wash first ( but not essential ) then use 14% hypo mixed 50/50
15 mins dwell rinse off
Repeat if not completely gone

Is there any reason why I shouldnt use hot with hypo?

I can't remember the exact reason without trying to go back looking for the answer - but do recall hot water has an adverse effect on how hypo works

Easiest way is buy cheap chick toilet bleach squirt it on brush it in leave for 30 muinits rinse off looks like new , and costs £1 a bottle , or hypo mix 4-1 if that doesn’t work do it a bit stronger until you get the desired results .

Yes cold water with hypo warm to hot water with biocides 👍

I'm with splash & dash, thick bleach from aldi at about 40p a bottle, squirt it on, brush it in, leave to dwell for 30 minutes, and rinse off should come up a treat.

Got these on my house tried cleaning with bleach didn’t touch it so ended up painting them .
They look like new now.

I thought that bleach and plants under the sills aren't an ideal combination.

cover them over and rinse them off after
bleach will take the colour out of the leaves but rarely wipes out a complete plant

Looks like stone chippings under the sill, can't see any plants in the picture?

If you're doing the first floor sills too (and the ground floor) just be careful of the runoff.

I took the question to be general - where you might encounter the green stuff - not this particular job
