I recently did some pw work on a house where the home owner wanted me to wash a side of his that mildrew was growing. The siding was stucco and the garage doors were wood. I pointed out a layer of white residue that was on the garage door prior to the cleaning. I presoaked and applied my house wash (simple cherry/bleach) solution to the side of the house and the garage doors. However later when it dried the residue came back and it it seemed worse, it looked like the wood was faded. I was consciense to not allow the soap to dry. Does anyone know what could cause this? The fading residue seems germaine to the wood.
