Any sure way to remove oil and grease marks left on paving stone driveway?
Answer:
I've found that soaking them with WD40 and then sprinkling sawdust or kitty litter on it to make sure it doesn't dry for a couple of days works very well. You have to put a board over the sawdust in the meantime so the wind doesn't blow it away. After a couple of days you can sweep it up and then wash the spot with a garden hose. You may have to go through this a couple of times.
