Cedar is a soft wood, and the force of a power washer, while it will take the paint off easily enough, will also very likely damage the wood and drive moisture deep into it, causing your future paint job to peel off later.
Things You Will Need
-
Set up your ladder at the highest point on the exterior wall.
-
Work your scraper from the top of each shingle toward the bottom, in steady, even strokes with the grain of the wood. Hold both blades of the scraper against the wood firmly, but don't press so hard that it gouges. For tough areas, scrape lightly several times rather than trying to scrape heaily once. Get all the loose paint off. Leave the paint that won't come off with three or four scrapes.
-
Continue scraping as far to either side as you can safely reach, and as far down.
-
Once you've scaped all that you can, take your stiff brush and scrub over all the siding from side to side (the opposite direction from that of scraping) to take off any residual dirt and dust. Make sure to get up into the lines under the bottom edges of the shingles.
-
Move your ladder to a different section and repeat the process.
