Oak Stain

[chopperpete]

Got some nice oak freshly cut to eventually burn in my wood stove. Left it on my trailer few days outside in the rain found a large brown stain on my nice new concrete drive. Found it very difficult to jet wash clean. Will need brick acid at a second attempt to clean it up.... just a warning to others.....

Oak was passed fit and healthy 18 months ago (ps not my work!)

Bleach has worked for me in the past, had a terratzo floor stained by a hardwood frame.

 

Tried all sorts of cleaners, bleach got rid of it.

 

Brick acid will dissolve you drive, Hydrochloric acid is the active ingredient..

 

Try on a small spot first.

Try something with citrus in it.

Oxalic acid will remove it, dilute some in water and wipe on, wait 10 mins then wash off

This may sound stupid but try ........ washing powder works on oil ,just dampen area pour on powder dampen leave for half hour scrub with a broom and hose down .Worth a try ?

We had the same problem with Horse Chestnut, tried all sorts but in the end had to wait for nature to do its thing. The stain has dulled now but never went 100%.

 

I like the screen around your work site, did you erect that.

Thanks for your tips. The work was screened off as it was in a cemetary. Not my job, I was just offered some wood.....
