Will TSP hurt my flower beds?
I really didn't know where to post this question. I'm hoping someone can help me out. I tried a search of all of Garden Web and "This Home Place" and came up with nothing. So if I should post it somewhere else, please let me know.
We are getting ready to paint the outside of our house (aluminum siding). My DH wants to first pressure wash with something called TSP, I am concerned about this stuff running into the flower beds that are along one side of the house. Also, if he uses it on the dormers than it will run into the gutters and out onto the lawn - will it kill the grass?
Any help is appreciated.
