Before You Start

Prepare a designated cleaning area and ensure towels are sorted by color. Check care labels for heat and washing instructions. Use hot water where allowed to maximize odor and microbial removal. Avoid overloading the washing machine to allow proper agitation and rinsing. Plan for a two-cycle process if odors are strong.

Step-By-Step: How To Clean Sour Towels

  1. Pre-soak towels in hot water mixed with a recommended dose of enzyme laundry booster for towel odor removal to loosen organic buildup.
  2. Run an initial wash with towel odor eliminator laundry detergent on the hottest setting allowed by care labels.
  3. Use a second wash with a small amount of bleach-free fabric sanitizer for towels to neutralize microbes and odors without bleaching fabrics.
  4. Run a dedicated cycle with washing machine cleaner descaler tablets for odor control to remove residue from the machine that can contribute to sour smells.
  5. Rewash towels if odor persists; consider adding another dose of enzyme laundry booster to reinforce odor breakdown.
  6. Air-dry towels completely in a well-ventilated area or outdoor sun if possible to further inhibit bacteria growth.
  7. After drying, spray a light mist of microfiber towel deodorizing spray on towels to refresh scent and comfort.
  8. If odors return, repeat the cleaning cycle focusing on the washing machine’s drum and seals using the descaler tablets first, then the enzymatic booster and detergent.
  9. Inspect towels for residue or stiffness; if present, run a final rinse with an extra rinse option in the machine.
  10. Store towels fully dry in a dry, ventilated closet to prevent musty odors from reoccurring.
  11. For frequent odor issues, establish a monthly cleaning routine using the cleaner tablets and odor-eliminating detergent as a preventive measure.

Troubleshooting

Symptom Likely Cause Fix Prevention
Towels still smell sour after washing Residue buildup in washer or towels Run washer cleaner cycle and rewash with enzyme booster Use regular odor-control cycles and don’t overload
Musty odor only in towels, not in other laundry Insufficient drying or moisture retention Dry thoroughly; use a shorter, hotter rinse Line-dry when possible; ensure complete drying
Towels feel stiff after washing Over-use of detergent or hard water residue Reduce detergent amount and add an extra rinse Use fabric softener sparingly or none; consider water softening
Machine drums sweat odors after cleaning Residue in seals or gasket Run a purifier cycle with descaler tablets Clean seals monthly and keep door dry between uses

Common Mistakes

  • Using hot water on towels labeled as colorfast without checking care labels
  • Overloading the washer, which prevents thorough agitation and rinsing
  • Mixing too many cleaners at once, which can leave residues
  • Skipping the machine cleaning step, allowing residues to cycle back into towels
  • Relying on air-drying alone in humid spaces, which can promote mildew

Adopting consistent routines and following product directions helps prevent sour odors from returning.

Tips For Best Results

  • Pre-treat spots or residue on towels with a small amount of enzyme booster to break down oils.
  • Choose a washing cycle with extended rinse to remove all cleaning agents from fibers.
  • Use bleach-free fabric sanitizer to protect colors and fabric integrity while neutralizing odor-causing bacteria.
  • Regularly clean the washing machine’s gasket and dispenser to prevent buildup.
  • Store towels completely dry and avoid damp storage areas to minimize mildew growth.

Call A Professional

Contact a professional if towels or the washer emit strong, persistent odors after multiple cleaning attempts, or if you notice visible mold growth inside the washing machine. Seek expert help for persistent reservoir or seal issues that a homeowner cannot safely address.
