Every time I look at the price for framed stencil cleaners, I turn around and go back to my vat of IPA and nylon brush and keep on keeping on. Put stencil in vat, soak a few minutes, scrub with nylon brush, rinse, air dry, put back on the shelf.
I don't do super fine pitch components though, 0805 and SOIC are about as small as I get.
