The mini-blind cleaner is an open framework from which a mini-blind to be cleaned may be suspended. Suspending the mini-blind from the mini-bland cleaner allows both sides of the mini-blind to be accessed and allows operation of the mini-blind mechanisms that raise and lower the blind and tilt the slats of the mini-blind. The mini-blind cleaner comprises telescopic upright sides that may be reduced in length. The upright sides are also hinged to the top frame so that the mini-blind cleaner may be folded flat for storage or transportation. Movable blind brackets on the top frame lock into position at spacings corresponding to standard blind lengths.
