Scenario 1 – Your paint job was done about two years ago and you decide to change the color. If there is very little mildew, you may be able to just hand clean the dirty areas.
Scenario 2 – Your house has not been painted in 8 years. When you rub your hand across the surface it is covered with a powdered chalk. Also upon examination you also see black mildew spots. In this case O’Connor’s Painting Service would apply a cleaner for the chalk and mildew surfaces. We will then power wash the largest areas always using a low pressure. Around windows and doors, we always clean by hand. Good quality cleaners like Krud Kutter or Jomax can be found at all paint stores, home Depot or Lowes.
