Accidentally powerwashed limestone - is this fixable?

I have an electric pressure washer for home use. I asked my patio contractor for advice on how to clean the edging stones on my patio, and he told me they were sandstone and I should go after them with my pressure washer. Turns out he was wrong, and they are limestone. I should have double checked on my own, so totally my fault and I feel super dumb. It was all black when wet and I couldn't see what the effect was, during. When it dried, it looks like the image - like it's been scribbled on by a child. I tried going back over it with the patio cleaner head for my pressure washer, but it didn't change anything. Is this fixable? If so, how? Any advice would be appreciated. Thanks for your time. For reference my powerwasher is a Bosch Aquatak 2000. submitted by /u/Uxish [link] [comments]
