Hello everyone
I was wondering if some of you would know how can I clean my patio off cement stains on some of the flags (riven type).
Thank you very much.

It is Riven style flags from Marshalls
Thank you for the link, very informative indeed; what a great site.
I was going to try acid cleanining chemicals, but I will first try and wash with hot soapy water & brush with a steel brush before doing anything drastic.

The acid may change the colouring of those flagstones. If you do feel you need to resort to such measures, make sure you test a discrete area first, and leave it for 24-48 hours, as the effect is not always immediate.
