w116 diesel oil change gone wrong

[xaliscomex]

I don't really know where to post this one but since my w116 300sd is to blame then I will post it here. Changed my oil on Sunday night and let the oil drip from the oil cooler and oil pan overnight. Monday morning I put back the drain bolt and put back the oil cooler line. Around noon, I drove my car out of the garage and dragged a shallow bucket containing nearly 2 gallons of used motor oil and flipped the bucket onto my driveway. Nightmare. My driveway was not only stained but the oil splatter made my concrete look like it rained oil on it. This happened 20 minutes before my dental appointment so I only had time to start the pressure washer and shoot water onto the concrete surface to wash down the oil...bad idea...I had no dirt, no cat litter no soap to emulsify the oil. Made a huge mess all over the driveway. After my appointment I used detergent and scrubbed as hard as I could and only left stains. The brush was more effective than the pressure washing, obviously....I got home this evening and saw a County Vehicle right in front of my house and I immediately started to pace back and forth and waited for him to knock on my door. Well he never walked to my door but walked across the street to look at something on the sidewalk. Also this evening I saw a carpet cleaning van parked 3 houses down the street and I wondered if I was the one who caused the problem indirectly. I purchased a Techniseal product and applied it to the oil stains but the directions said nothing about shaking the bottle first so a huge clump of wet clay looking material could still be seen thru the bottle opening....what a mess...I parked both my cars on the driveway to block the mess and now I'm wondering how the hell I'm going to clean this one up...for all of you mechanics or shade tree mechanics, how have you handled this type of incident in the past? What is the best approach and what are the best products to use? I need to clean my driveway up ASAP. I have an HOA(home owners assoc) that loves to walk the streets up and down to look for dead bushes, dead grass, trash cans left outside....etc...But what will they do when they see my driveway....Please...and I mean it...please advise....
And for those of you who haven't sealed your concrete...seal it now before its too late....
P.S. Im not going to blow torch my concrete driveway to get rid of the oil
