Wipe them down as best you can and either replace the screens or put them back in. Not a big deal unless weíre talking more than a few little chips and slivers.
There is an oil change kit which includes filter, seal, and 2 new screen assemblies.
I did the 600 mile change and put them back in after cleaning as well as I can with q-tips. Iíll do another oil change and swap out the screens at 2000 miles. Thatís just how I like doing it, not that itís better than any other way.
