The Scotch-Brite™ 7445 pad is rated ultra fine for general light duty cleaning and polishing. Useful to remove tough valve piston stains that don't come out completely during the chemical flush process. Use with valve oil to lightly work the area of the stain. Do NOT use anything with a more aggressive grit to avoid scratching the piston face.
