Love this stuff

I haven't used Ultra One yet. Who all uses it and for what applications?

I had dry wasp spray on vinyl shake. It was the only thing in my truck that worked.

I used it to remove the black staining over a gas fireplace exhaust hood. The white soffit and gutter above was completely black. The Ultra One removed it with a little scrubbing.

Sounds like some must-have cleaner to keep on hand.

Indeed it is.

Today I had to get the Ultra One out again. Wasp spray on vinyl siding again. Now that I know what it looks like I can clean it with Ultra One and move on. Wasp spray looks gray when it drys.
