Render clean for a friend - Advice please

[vinchenzo19]

Hello all.
One of my friends (also a window customer) has some black mould staining around her bathroom window and asked if I can try and get it off.
I thought soft washing with a flocked brush and done kind of eco cleaner? Ideally wants to be as cheap as possible for me as I probably won’t use the chemicals again for a long while unless I add it as a service in the future perhaps.

What are your thoughts?
Thanks in advance

Can you not try with a diluted household bleach initially. If that doesn't work then some Lightning Cleanze should remove it

Cheers part timer. I thought of that initially but wasn’t sure if that was ok to use on rendered walls? Perhaps I’ll just go easy on the mixture?

A bleach solution should remove that - if you have. backpack make up a solution in that and use your brush to apply and agitate

Cheers Windy. I have a Gardiner v3 I was planning on using to rinse down with. Wasn’t sure about running chemicals through it.

Will be ok as long as you run pure water through it straight after

Get some poundland mould and mildew spray. It's worked for me

Cheers AW. I’ve just brought some D-Green to try. The lady has cats and a fish pond close by so I’ve opted for this to be on the safe side.
