Trash bags and painter's rags are essential disposable and reusable cleanup supplies kept on site at all times during painting projects.

Heavy-Duty Contractor Trash Bags: Extra-thick (typically 2 to 3 mil thick) heavy-duty bags used to hold wet masking tape, used plastic sheeting, roller covers, sanding dust, and paint cans without puncturing or tearing.
Painter's Rags in a Box/Bucket: Absorbent cotton rags (often sold in bulk boxes or buckets) kept within arm's reach to immediately wipe off wet paint splatters, clean tool handles, wipe down surfaces after sanding, and dry washed brushes.
