If you have severely stained Cedar siding, you can power wash it with a wide nozzle and low pressure. Cedar siding is durable but can be damaged easily by excess pressure, especially when it is aged or very dried out. You should only use a wide nozzle, because the narrow stream of a straight nozzle is capable of drilling a hole in the soft cedar.
Let me expand on this:
First, make sure the siding is fastened well to the house. Even at low pressure, you can break loose cedar shingles. If you have to secure any loose shingles – ONLY USE SIDING NAILS! (other nails may rust or corrode and streak the siding). If you don’t have – or want – a power washer, You can even use garden hose with a pressure sprayer head like this:
Crusar Brass Water Jet Power Washer High Pressure Hose Nozzle Pressure Sprayer for Car Washing Vehicle Washing Pet Washing Gardening Outdoor Housecleaning Window Cleaning – From Amazon, it uses 60 PSI home water pressure, not 1800 psi power washer pressure. I have one and use it for light duty work.
Second, using a good cleaner BEFORE power washing to remove and brighten the siding will make the job easier with less power washing.
