Yes. Just dilute some with water

I would like to wash my house sidings, driveway, and sidwalk... will pressure washer chug through this entire container? How long does it last?

You will probably need two jugs of this Simple Green stuff. I had to buy the second jug at Lowes when I ran out. We did our deck, chairs, windows and siding. In front, we did siding and windows. Used about one and half jugs. Towards the end of your job, add additional Simple Green to the tank sparingly since you will have to clean the tank and lines anyway. Otherwise, it's wasted. The trick is to come out even, finish the job just as the soap dispenser goes empty. Of course, it all depends on which power washer you are using.

Which simple green product is best for removing mildew / mold?

I think it depends on what the surface is. If this is a surface to be painted, you should try Simple Green Paint Prep Mold & Mildew Stain Remover. If tile or something similar the 'regular' green formula will work well. If outdoor, there is a house and sliding formula that can be applied with a pressure washer or pump sprayer. The 'purple' heavy HD is safe on aluminum and works as well as the 'green'. Hope this helps!

I know everybody loves this, but does it have a chemical-ly odor? Since 9-11 there's stuff I can't take.

I am very sensitive to odors (I can smell lettuce and other mild smells) and I think that the smell is mild. It does smell like a cleaner but I don't consider it to be a solvent or an industrial chemical odor.
