    http://en.wikipedia.org/wiki/Sodium_hypochlorite

    The sodium hypochlorite I buy is 14-15% in 25 ltr containers that you can get frome most local pool suppliers etc.

    Myself I use hypo manly for hard surface cleaning diluted down to about 7% to clean paving, rendered walls etc as kills algae, black lichen, moss etc.

    I also have been known to use hypo on plastic cladding, guttering & fascias but at a much reduced mix with a suficant like tfr to be on the safe side as I don't want my mate frank to **** jobs up. :D

    Do you reckon hypo would be ok to use on sandstone ledges Smurf? I have an estate where the ledges below the windows have turned black. Would it have an effect on the glass if it spilt on it ?

    I have never used it on sandstone myself so could not say if it would cause any damage to the soft stone or not. Likewise with any strong chem caution should be taken if it gets on glass and should be washed down thorougly to prevent it staining glass. I'm aware that some have caused permanent damage to glass when using strong acids on brick/stone cleaning jobs.
