Here s how to take on the task. If you do use tsp then i would also clean the residual tsp off the piece of furniture with a clear water wash or denatured alcohol. Painting season may be waning and you need to paint sooner rather than later. Painted wood takes a little extra care to clean but that doesn t mean it s impossible.

Time is of the essence. Before painting apply primer to the old wood surface whether it is indoors or out. But there is no point whatever in cleaning bare wood with tsp or latex painted wood with tsp. If there are creases or hard to reach small places on your wooden surfaces use a small scrub brush or toothbrush to clean it.

If you have an oil based paint on your wood then i d clean them with tsp if you intend to repaint that wood. You want the absolute best adhesion surface for your paint. Paint cracking on walls and ceilings happens due to a variety of causes one of the most common being poor preparation of a surface prior to painting. You can then sand the entire surface to give it a more textured surface that your paint will easily stick to.

This is also a good time to scrape any old flaking paint off and to sand down old paint lines. It is important to remove any flakes from the surface via sanding or scraping before repainting. Painting over cracked paint is a bad idea. There are ways to safely clean your house before painting using a pressure washer including using lower psi pressure washers widening the spray and standing at least two feet back.
