We had someone waterproof our deck with a stain watersealer. He let some spill on our deck below. We tried muratic acid, but it did not work. Any suggestions?

Wood Deck Strippers: HD-80 (Heavy Duty Stripper) was formulated to break down and remove even the toughest wood deck finishes fast. HD-80 was designed to be sprayed on the wood deck surface and allowed to dwell for about 15 min per coat of finish that is being removed. Hd-80 is a powerful caustic formulation and requires that surrounding vegetation be masked. Because of HD-80 high pH it will raise the natural pH of the wood and cause some species of wood to darken. Whenever you perform a strip job, you want to return the wood to it's natural color and pH. This can easily be done with the application of a Brightener / Neutralizer. Good luck.
