I loved your tip about cleaning outdoor cushions with a pressure washer. I bought a pressure washer for that and some other cleaning activities. My pressure washer has several nozzles and a detergent dispenser. I was wondering if you know the force you used and if you would recommend a detergent specifically for power washers. Simply Green Oxy seems to have good reviews. I have a LOT of cushions to do and this will save me over $2,000!
