LMAO.... my HD doesn't have TSP in stock. Figured I'd check Tractor Supply. Apparently I can use cat food.

 

Thar she blows...

 

I'll take the Explorer!
(The BMW really shocked me.)

 

That was frickin awesome!

 

That wall is sure nice and fricken solid. .. must root pretty deep.

 

A bigger pressure washer, concrete sander, WD40 and a wire brush...for real.

 

Wow.... that BMW was toast!

Exactly what I was thinking. Almost seemed like AI.

Might have to do this.... thought about paying someone to come do the whole driveway. Might be expensive though.

 

Those round things work the best on a big washer...at least a 3500 psi. I used a broom attachment which was good enough for me. Just a bar with with 5 nozzles on wheels that you could flip around and wash the underside of your vehicle.Those circle types is what they use today for concrete, -

I actually have one of those attachments... never used it. I bought it right before my old pressure washer shidded itself.

 

LOL

You would need a commercial set up for the tough stains on concrete. Even that's no guarantee. The more pressure the better when it comes to concrete stains. Specially with that attachment..as it's set up to deliver pressure equally over a wider span. Requires a beast of a machine. Oil stains are the worst. I doubt your driveway is even close to being in that type of bad shape. In your case, that rust stain, I'd just keep experimenting until you find something that works.

Perhaps you can get a guy to come over to do your drive for a good a price. The drive would probably look goofy with one clean spot anyway. Say to him over the phone that it just needs a quickly , it's not that bad. Then give him your dimensions. If it's just the one stain, don't mention it until he gets there. I'm sure he would put a little extra effort into that if he needs to...and if he knows you want that gone. Might want to say something like, if you can't get it , no big deal. Chances are he really crank it up then...just to appease you. He's in challenge mode now.

You know white....just sort of talk the talk with the guy. Get him on site first though.
