Last weekend I cleaned off a number of random items at my house. I scrubbed with baking soda and diluted vinegar and then washed them off with a pressure washer. I made the unfortunate decision of doing that cleaning work in my lawn. I'm now looking at some pretty large sections of my yard that are dying off.

I'm wondering what I might do to remedy this situation. So far I've thought of:

1. Water the lawn a ton. Flush out the baking soda and vinegar as much as possible.
2. Baking soda has a pH of 8. The vinegar was pretty diluted. Perhaps I could apply a nitrogen fertilizer to try to lower the pH.
3. After flushing the soil with a lot of water, throw down some new grass seed, cover with a thin layer of dirt and water a few times daily for short intervals. It's the worst time of year to get to try to get grass seed to germinate, but hey I'm desperate :)

Any other thoughts or suggestions? Thank you!
