Hello all. First time poster here. Ive been in the business for 5 years now and wash over 600 houses a year. We usually shut down from November till March due to cold weather and the gutters not cleaning well. Im debating buying a hot water washer this year so we can clean longer. I figured if i heat the gutters up they will clean better. What is the maximum temperature that you can wash vinyl with without damaging it? Also what do i need to be aware of using a hot water system. Thanks
