The Tok design is tailor made for cleaning by dunking. The action just lifts out and can go into it's own swirl around tin or tray for cleaning and lubing. Once out the rest of the gun is almost wide open. And the plastic grips, though cheezy as heck, won't be damaged by washing in water, solvent or from the final oil. These things are actually a brilliant design in so many ways that I can't help wondering how much better it could be if the frame and magazines were just a little longer to suit larger hands and if they were made to a higher level of fit and finish to ensure a higher level of consistent accuracy.
I haven't ever looked up what sort of cleaning is needed to get rid of the corrosive residue. But if it IS hot soapy water then you could do worse than to field strip the gun, lift out the hammer action to be dunked in it's own little tin and then dunk and swirl the rest in a tub of hot soapy water, rinse well in extra hot water then shake out, blot the excess off, blow dry with a hair dryer and then swab everything down with some WD-40 or some homemade Ed's Red and blot off the excess with some paper towel and barrel patch. Then a drop of CLP on the slides when re-assembling the slide and yer done.
The action needs a touch of extra attenton. The big pin is held in by the hammer spring pressure but the smaller pin for the disconnector is free floating. So be careful to not lose it when you are handling the action. Just learn to hold it by that area so it can't jump for freedom. Dunk in hot soapy water, rinse with hot water, blot, blow it dry with a few hard mouth puffs and some more hair dryer action then oil it up with CLP and insert during re-assembly.
The whole thing from start to finish shouldn't take more than 20 minutes even including the slow part with the hair dryer.
If you've got those slip on stretch grips I wouldn't dunk the whole frame. The grips would hold too much water and it would never dry in there. Instead just brush out the dust cover area and maybe push a damp rag down through the mag well to clean it followed by a light application of oil using an old toothbrush to hit all the spots.
