Product review (4 stars): Great sock soaker!
I bought this for the sole purpose of soaking my white socks.  I like to wait until I get a load together to wash in the regular washing machine...so maybe 7-10 days.  I like my white socks WHITE.  Just tossing them into the laundry basket and washing never keeps them white enough for me :)  I put some hot water in this in order to dissolve some OxyClean Versatile, then just keep tossing the socks in as they get dirty...give it a spin or two with each added pair of socks, then toss them into the wash with the towels and such once I have a full load.  My socks are white, white, white!  It is a bit bulky and cumbersome and sometimes the cotter pins don't stay in place, but that could just be because I don't have them in correctly.  I don't know that I would like to use it regularly to actually do laundry that requires emptying and refilling to make rinse water, etc., but it suits my purpose well.  I am glad I purchased this.
