This may sound funny but have you considered a vice with rubber jaw covers and power sprayer? You can also use use a pot of boiling water to loosen the debris and some cut proof gloves for final handling. just be careful if you have plastic parts or elastomers/seals.
Yep sounds funny, smart - but funny. I’ll just say easier for you than an me - in Chicago. Dishwasher no soap? I was also thinking of slicing up a sponge that could reach into the multiple crevices, it would look like piano keys I guess. Just wondering if there was a duh why didn’t I think of that type of solution. Yours is good Zilla- just not practical for half the year in my neck of the woods. Thanks!
i just hose them off with hot water reel good then scrub it with a nylon bristle brush with soapy water then spray off again. definitely a pain but it works.
