You can use the spray cleaner while working from a ladder -- although scaffolding is better -- but practice at ground level first; the force of the spray against the house could knock you off a ladder if you're not careful. Some of these machines come with separate containers you can fill with cleaning solutions or anti-mildew solutions. Sprayers are so powerful that ordinarily you probably won't need to use a cleaning solution; if you do, remember to rinse the surface with clean water afterward.
The psychological effect of green is largely dependent on the tone or hue. Some green hues create a positive, natural atmosphere. However, darker hues or pale olive green can seem militaristic or ill. Multiple shades of green can serve different purposes and set different moods. Maritime greens are ideal for studios and offices as they inspire concentration, while cool forest greens can be used in bedrooms and bathrooms.
