brand new patio - indian sandstone
« on: August 15, 2018, 04:09:43 pm »
guys
we're window cleaners
we went to a property today with a brand new, Indian sandstone patio, completed on one week ago.
Cost £14,000.  !!

I did notice how immaculate it was a week earlier when I was there to price.
So today,
we're there to clean gutters, soffits, facia and windows
on completion of our job we noticed some dark and light grey patches where we had been stood and working from
before we started the patio was immaculate - so could only have been caused by us,
genuinely have no idea how !!
we scrubbed it with flowing water and a stiff broom  - for ages,
made absolutely no improvement what so ever

can anyone help ?
can anyone clean this for us ? 

thanks
Rob
nr. Brentwood - Essex (cm15 0s)

There was NO sealant on this brand new patio as they were told too wait for the salts to come out !

Have you been back to check that it has dried out and OK now - sometimes you can leave dark footprints on Indian sandstone when walking on it in the cleaning process and they don't rinse off just fade when the stone dries.

To be honest as a last resort  i'd be tempted to try a weak solution of Sodium Hypo-chloride administered with a paint brush on the smallest piece of affected stone you can find, agitate with a stiff brush and then rinse off well with water - That's only an opinion though

You could try ringing Mark or Paul at Spinaclean - These chaps have got me out of trouble in the past and they are nice guys
