Trick I discovered with my windows that removes using the ladder. Extendable car was brush, some dish soap in a bucket of water and hose. I scrubbed the windows with the brush, then hosed them off. Surprisingly there were no water spots or streaks.Standing on the ladder I find I stretch the calf muscle because the heel of the foot is setting lower than the ball of the foot on the rung when I balance to clean windows. Usually doesn’t hit me until the next day.
I’ve pulled back of the thigh muscles when I knelt and bent over the bathtub to wash little dogs.
