I was helping my friend with his car – long story short, an accident happened and there is a huge oil river down my driveway.
Now, I immediately soaked it up with this special powder that is designed to take oil stains out. Then I tried this commercial concrete cleaner that claims to be able to remove "any stain." [[It had muratic acid in it.]] I have a pressure washer and have been using that too. Then I tried this chemical that is used for cleaning oil painting brushes… that worked alright.
All these things have dulled the stain quite a bit. But my driveway still looks like a skunk. I was going to leave that special powder on it overnight tonight, and see if it’s any different by morning.
So my question is: Does anyone have any other REALLY GOOD ideas? I don’t want any stupid answers like kitty litter or "just paint the driveway." Something that you know for a fact works well on a huge stain. I mean, HUGE.
Thanks so much! I’ll give 10 points if your remedy really works.
