once more.. boring but important and i won't post too soon this time

[stuffitllama]

There are orange marks on the white patio of our rented house and I need to get them off, I don't know if they're cigarette burns from a party or rust from a table nail. Can I sandpaper them off? Can I use bleach? Thanks for advice info or links. Have tried to google but not much luck. If anyone's had to do this i need some tips!

What sort of patio? I would certainly experiment with bleach on a relatively unnoticeable one and see what happens.

Sorry - no direct experience since patios we have stained have always been ours and not rented, so the stains just stay there.

Who lays a white patio, FGS?!

well quite
we didn't know it was white actually until someone lent us a jet spray
now it's nice and clean and... a bit blotchy

lol at staying stains.. good ideea to try bleach in unnoticable area

thanks
