Tree sap stained Indian slate, Help needed.

Posted by Andrew Michael Palmer on June 15, 2013 at 9:34pm
Hi all, (this has been posted on arb talk forum as I'm desperate for advice to solve this issue), but here goes on here.....I left 20-30 Laylandi tree logs for a friends Dad on his Indian slate in his rear garden. Now I'll always put this on a sheet or on the lawn.From the title it's stained his Indian sandstone slate, he has tried most things to remove the sticky sap and stain. His tried jet wash, boiling water, fairy, nail varnish, has not tried petrol yet, tried wd40 but its stained and kept an oil base residue on the tile he can't get rid of argggggAny advice would be very welcome indeed.I'm going to contact HG international on Monday however any help or tips would be great.Kind regardsAndrew

    Hello

    I had the same thing last year with sap from a green oak building, and we hadn't even finished the garden, I was panicking,

    I ask on here and people suggested some expensive products however reading the properties I realised It was the same as common household bleach, I tried a small bit it worked! So carried it out on the rest. £1.59 and a bit of scrubbing problem solved.

    I've seen MMC Pro take off 90% or so of Birch catkin staining on Sandstone. The rest has now receded to the point it is not noticeable.

    I do not think it the ability to deal with oil based staining tho :-(

    As with any product whose outcome may be unknown, a bit of testing will be necessary

    its only a suggeston as i have not tryed it a sheet of bloting paper covered with brown paper then apply a hot iron ?

    Are you sure David this is Indian slate exterior patio tiles, not a carpet stain.

    Does anyone know why I'm not getting email updates to these replies on this thread. Don't seem to have this issue on joined threads or new threads I've started!

    lithofin oil-ex for the oil stain

  • Dan Frazer Gardening June 16, 2013 at 4:55pm

    I had a call with exactly this problem and am going to see it tomorrow. My plan was mmc pro and see how that goes, then pressure wash if it didn't work, but bleach sounds like an easier and probably more effective option.

  • Simon Smith June 16, 2013 at 5:35pm

    Hypochlorite etc will shift almost anything but you need a specific oil remover for oil. All of the lithofin stuff is pretty highly regarded as stuart suggested.

    Putting WD-40 on it sounds like a bad idea...

    I've had
    Good success with oxalic acid, on a variety of stones, but obviously test a patch
