Do these towels need to be washed before use?

Yes—wash them separately in warm water before your first detailing session to remove any manufacturing residue and maximize absorbency. Skip fabric softener and dryer sheets.

Can I use the same towel on wheels and paint?

Not if you want the best results. With 48 pieces, dedicate one or two cloths strictly to wheels and brake dust, then use fresh ones for paint and glass. Wheel grime is abrasive and will scratch clear coat if dragged across it later.

How do I store these to keep them clean between jobs?

Wash after each use and air-dry or tumble-dry on low. Store in a sealed plastic bin or ziplock bag to keep them dust-free. Keeping them dry prevents mildew and keeps the fibers soft.
