I can financially see the bottom of my pool, it’s not as green anymore, making progress. Now I’m dealing with sand stuck to the side walls, I think this happened last fall when contractors sanded down my concrete patio to redo the overlay, they must have blew the overlay mix they sanded off into the pool. I haven’t used the pool since October so I’m just seeing it now. I’m scraping it off but this will take forever, is there a liquid solution that I can use to dissolve this sand off the side walls.

Is there no copyright infringement on vehicle designs?
