I rinsed my fork tubes with
SeaFoam Engine Treatment (100% petroleum distillates): I added 2-3 oz. of SeaFoam to the old fluid in each tube, prior to draining, then I pumped them up/down 5-10 times, to circulate it through the upper/lower portions, to mix it thoroughly, and to allow it to dissolve any deposits within the tube assemblies; after that, I drained it, and added fresh ATF fluid.
If you are concerned about it, re-do it. ATF fluid is cheap, you can be certain it is completely flushed, and you will be able to re-torque the screws to proper levels. Cheers!
