I want to thank you very much for this video as I have my beautiful home back again. I was wondering if I could mix the solution and run it through a power washer next time as it took forever with a weed sprayer. If I could then I could at the same time rinse more stubborn areas on my gutter. Didn’t know if the solution would hurt my power washer if I ran clean water through it afterwards. If a power washer is not recommended then what would you recommend for bigger jobs like pole barns etc?
