Do all these cleaning methods work on pavers like they do on concrete?

There is never a problem until there is a problem. I am siding with the OP about this issue.

In New Jersey, I had a house washing company tell me they would not be able to get off the tiny black spots that "Shotgun Fungus" left all over the vinyl siding on our home. I said to go ahead and try anyway. The pressure wash did not get those spots off. At least I was informed before he began the job that he knew they would not come off. This is what No Pressure House Cleaners should have done if he knew his method was not going to get out oil stains. And......if he didn't know his method would not get out oil stains, he should not be pressure cleaning houses.

Muriatic acid and hydrochloric acid are two separate acids. One is NOT a diluted version of the other. Both will work to clean driveways.

Very true especially if he knew or should have known his truck was leaking oil.

Bad slam on “No Pressure House Washing” we have used them for years great job friendly staff , reasonable price twice a year cleaning ,no high pressure blasting of soffits and siding. Will do driveways and sidewalks to remove black stains from dirt or mold. Oil is almost impossible to remove from concrete or stucco.

No Pressure is a great company, never an issue.

Kitty litter. Absorbs much of the oil, but not after it has been long enough to set the stain

Won't you have cats peeing on your driveway?

We’ll actually, they are the same acid

Call it diluted or call it impure but muriatic acid is the same HCl as hydrochloric acid

I use paint thinner for oil spots

Correct...

What Is Muriatic Acid? Facts and Uses

I worked for an asphalt company many years ago. The best way that we found to get oil off of concrete was to put clay kitty litter on it. Rub it in with your shoe and watch it disappear.
