I have discovered how to get my blinds blindingly white without harsh chemicals and scrubbing. Place a set of blinds in the tub, start filling with hot water, pour in a cup of baking soda, when the blinds are almost covered pour in white vinegar, watch fizz :) right before you turn off the water, squirt a tiny bit of dawn dish soap in the water stream. Allow to soak 5 min., drain and rinse.
For years, I spent so much time washing blinds while they stayed hung up. It was always annoying, back-breaking and arm-aching. I still never felt like I could get them clean enough! Then I heard about this trick!
