Siebert SR-5 Scratch Remover, 1-Quart

Siebert SR-5 is a mild acid plate cleaner, conditioner and scratch remover made for metal plates. This milky liquid removes minor scratches, calcium buildup, and ink/paper residues. Compares very favorably to other better-known products, including the once popular but now defunct Kodak 3M R Scratch Remover.
