The Brew Cabin

Hello again Tony.
Winter is approaching and I'm bored - decorating indoors is not as much "fun" ! When I was laying the drive I couldn't wait to get it finished , but now I'm looking at other areas I can do with the left over blocks :)
Anyway, I swept some leafs (mostly from a schumack(?)tree) off the drive today and they had left behind a dark stain. I tried blasting with a power-washer but it didn't "scratch" the stain. Any ideas ?

Sumach's aren't usually a cause of serious stains, not like them damn sycamores!

I'd try using a detergent and a spadeful of grit sand, and give the lot a good scrubbing with a stiff brush. Don't be tempted to use an acid-based cleaner at this stage, or it could discolour the section you're cleaning. If the detergent/sand mix doesn't work, I'd leave it until spring, as you may find that natural weathering removes the worst of the staining.

Have you thought about building a patio with the left-over blocks?? ;)
