I refuse to throw away a towel that still has drying ability... And I save the ones with bare zones for rags.
Use a rotary cutter to cut the towel up into squares and rectangles. Stitch the edges to have perfect rags for car washing, furniture polishing and more. Finished edges on the rags, make them able to withstand the laundry so they can be used again and again.
Watch for "rag suitable" fabric as you sew and save the scraps to make rags.
