I usually have information on pretty much everything, but this one has me stumped.
For determining the condition of ferrous material magnetic plugs there are lots of photos grading plugs from 1 thru 4 or 1 thru 5, like the example attached.
My question is has anyone ever seen any type of similar reference photos for the material found in the bottom of the pleats of a filter element..?
