How to Prepare Stains Before Machine Washing

Before pre-treating, identify the garment, the likely source of the stain, and any allowed treatments. Use a product formulated for that application; do not combine substances to cover unknown causes.

Separate loose material from adhered stain

Carefully remove any surface residue the garment can safely release, without spreading it or rubbing on a delicate area. Mud, grease, and a pigmented mark do not necessarily require the same treatment. An old stain or one that was previously heated may respond differently than a fresh one.

ObservationPreliminary decision
Surface particles or crustRemoval that is compatible before dispersing them in the load.
Grease or body soilProduct approved for that fabric and type of soil.
Protein-based soilCheck product instructions and temperature before applying heat.
Color change without residueDistinguish a stain from discoloration, which may not be washable.

Apply and complete the process

  1. Read the stain remover label and perform only the preliminary test it specifies.
  2. Follow the amount, contact time, and color or fiber restrictions. Do not let the product dry on the fabric if the directions exclude that.
  3. Select the compatible cycle for the entire load and account for any additional product.
  4. Check the result before drying with heat or repeating the treatment.

The enzymes are a formulation feature, not a guarantee for every stain. If new marks appear only after washing, follow their investigation instead of increasing the initial pre-treatment.

Reviewing before drying determines whether to stop the treatment, repeat an allowed application, or consult a different restoration method.
