Well I've landed my first commercial p/w job and in my normal fashion its straight in at the deep end.
Removing a large unknown (possibly oil based) black stain that has leaked out the back of a bin wagon all over a factory's yard
Doesn't look as bad as this now its weathered a bit.
I want to go fully tooled up with chems but not sure what to buy? Any ideas?
Was planning on wetting it up then scrubbing with some sort of degreaser let it dwell then attacking it with the turbo and then if its still there try hypo.
