Rally’s Ultrasonic blind cleaning is the ONLY way to thoroughly clean blinds. The service was top-notch — professional, reasonably priced, and exactly on time. There is simply no comparison to the quality and degree of cleanliness Rally’s delivered. Every thread in the blind strings is clean, not just the blind slats! In a short few hours they did what would take me days and their results put mine to shame. I will be using Rally’s from now on and give them my highest recommendation. So glad I found them!
