Dark Color T-Shirt Knit Rags are made from dark recycled cotton knit materials, including dark T-shirts, cotton thermal underwear, and similar cotton knit garments. They are designed for dirty jobs where stain hiding, cost control, and high-volume wiping matter more than clean white appearance.
With 70%–80% cotton content and common IMPA 232909 reference, these dark color shop rags are suitable for mechanic shops, marine maintenance, shipyards, metalworking, oil and grease wiping, machinery cleaning, workshop cleanup, and bulk industrial use.
