I use that 4 in 1 Algae remover on white plaster like yours which has the red stains. I spray it on and leave it, the red disappears after about a week. Mine is 9 years old and I have no intention of painting it for a good while yet!!

Hi,

I've just come across this thread. I am planning on cleaning my white rendered house-it's monocouche. Do you think the 50/50 bleach/water solution will work on this or could it damage it?
