The best one I've seen is a elevated pad to the side of the shop, sloped to the middle to a grate drain that came out to the side, thru a cement separator the width of a loader bucket. It made for very easy clean up. The pressure hose came thru shop wall up into the air to swivel drop for spray wand. Had a drain valve at the low point outside of shop to drain in the winter.
