Questions for Evaporust Users

it works best fully submerged, but I've had decent results with throughly saturated paper towels and covered in plastic wrap.

if I was attempting that here's how I'd go about it: on the outside seal the seams at the edges of the lips with some plastic wrap and really good tape. then I'd spray down the area that you're looking to treat. then use blue shop towels (or scrap t-shirts) totally saturated and laid up in there flat up against the areas. let it hang out for awhile and spritz it down every hour or so-- like basting a turkey-- depending on the heat while you work on something else. then I'd hose it down one more time real good before quitting for the night and seal it all up as best I could with some plastic wrap.

the next day I'd check the progress in one area and determine if I need to continue along with basting it and sealing it or if I'm good to go. at this point you may need to change out the towels (rinse out the t-shirts) if they're contaminated and you need more soak time.

the key is to keep it wet and let it work.

the other option is to find a trough that can accommodate the width and depth that you'd need and just soak it, but that would take quite a bit of product.

I can't help you with the answer to the grass. but I will say that the solution gets mighty gunky/dirty so I'd advise against hosing it off in the grass or anywhere you might walk.

ETA: it works best when warm, around 70+ or so. if you're below that it takes quite a bit longer.
