What is the best and most effective way to clean Venetian Blinds?

I spray mine with awesome,or fantastic in the bath tub with alittle water take a brush and scrub a little bit turn it over and do the other side and hang up to dry outside.If you can't dry it outside put a towel under one end stand it up dry mostly in an hour.

Take the blinds outside and place them open on the ground. Spray the blinds with a hose. Apply Dawn dish washing liquid on the blinds then scrub with a broom. Rinse and repeat if needed. Hang to dry

i use a spray window cleaner, on my blind cleaner
