Narrative:

I did a light duty aircraft shop clean on disc 281. I did the wash in my shop. I left the disc in the light alkaline tank 15-20 mins. I sprayed it off, checked it, put it in cold water, took it over to the table, washed it off, checked it, used a soft bristle brush on it, then I let it air dry.
