Quick answer

Hand-wash your Knuckles x Kuromi towel in cold water with a mild detergent, then air-dry flat away from direct sunlight. Never machine-wash or tumble-dry, as heat and agitation can lift the die-cut print. If the print already shows peeling, stop washing and switch to spot-cleaning only.

Why the die-cut print needs special care

The Knuckles x Kuromi Die-cut Hand Towel from KADOKAWA features a fused-edge print that sits on the surface of the fabric. Unlike woven patterns, die-cut prints can lift, crack, or peel when exposed to high heat, harsh detergents, or the tumbling action of a dryer. The towel measures roughly W210×H213 mm, so it is compact enough to hand-wash easily. Treating it gently from the first wash will keep the crossover design crisp for years.

If you already notice a lifted edge or small peeling spot, do not submerge the towel. At that point, any washing method risks making the damage worse. Instead, use a damp cloth to spot-clean the affected area and let it air-dry.

Step-by-step hand-wash method

Fill a basin with cold water and add a small amount of mild detergent — avoid bleach, fabric softener, or stain removers with optical brighteners. Submerge the towel and gently swish it for about 30 seconds. Do not scrub the printed area or wring the towel, as twisting can stress the die-cut edge. Rinse thoroughly in fresh cold water until no soap remains.

Lay the towel flat on a clean, dry towel or a mesh drying rack. Reshape it gently so the print lies flat. Keep it away from radiators, direct sunlight, and humid bathrooms. Drying usually takes 6–8 hours at room temperature. Do not use a clothesline, because the clothespin pressure can dent the print.

When to stop washing and switch to spot-cleaning

If the die-cut print already has a lifted corner, a hairline crack, or a small peeling patch, full washing will almost certainly worsen the separation. In that case, dip a cotton swab or soft cloth in cold water with a drop of mild soap, dab the dirty area, and blot dry with a paper towel. Avoid rubbing. This method contains the damage and extends the towel’s life as a display piece or light-use item.

Diagnosis: Is your towel washable?

  • Symptom: The die-cut print looks intact but the towel has a small stain or general dust. The towel is still safe to hand-wash using the cold-water method described above.
  • Likely cause: Previous machine washing, high-heat drying, or folding the towel while damp caused the print edge to lift or crack. If you see any peeling, the print bond is already compromised.
  • Corrective action: For intact prints: hand-wash cold, air-dry flat. For peeling prints: stop washing entirely and spot-clean only. Spot-cleaning preserves what is left of the print without risking further damage.
  • Stop or choose another option: If the print has a lifted area larger than a grain of rice, or if the towel is heavily soiled with oil-based stains, washing will not fix it. Consider displaying the towel instead of using it for daily drying. At this stage, the towel is best treated as a decorative collectible.
