How to Use Bluing in HE Washers

Published in Laundry Whitening 4 mins read

Using bluing in your High-Efficiency (HE) washer can brighten whites and restore their natural brilliance, but it's crucial to dilute it properly and add it at the right time to prevent staining and ensure even distribution.

Bluing works by adding a temporary, extremely subtle blue tint that counteracts the yellowing that often occurs in white fabrics over time, making them appear whiter and brighter to the eye. Unlike bleach, it doesn't remove stains; it optically enhances brightness.

Essential Steps for Using Bluing in HE Washers

The key to successful bluing in an HE washer is always dilution and precise timing. Never pour concentrated bluing directly onto fabrics or into the detergent dispenser.

  1. Dilute the Bluing: This is the most critical step. Always dilute bluing in cold water before adding it to your wash load or rinse water.

    • Mix a few drops or up to 1/4 teaspoon of bluing, depending on the size of your wash load, in a quart or more of cold water.
    • Tip: Start with less bluing than you think you need; you can always add more next time.
  2. Prepare Your Washer:

    • Load your white items into the HE washer. Ensure they are clean and free of heavy stains, as bluing will not remove them.
    • Do not add detergent at this stage if you plan to add bluing during the wash cycle.
  3. Add Diluted Bluing: You have two primary options for adding the diluted bluing in an HE washer:

    • During the Wash Cycle (Recommended for Evenness):

      • Start your normal wash cycle for whites with cold water.
      • Once the machine has filled with water and the agitation (or tumbling) has begun, pause the machine.
      • Slowly pour the diluted bluing solution directly into the wash drum, ensuring it disperses evenly and doesn't concentrate on one area of fabric. Avoid pouring it directly onto clothes.
      • Resume the wash cycle.
    • During the Final Rinse Cycle (Best for Avoiding Interaction with Detergent):

      • Let your washer complete its wash and initial rinse cycles.
      • When the machine begins its final rinse, pause it.
      • Slowly add the diluted bluing solution into the rinse water in the drum.
      • Resume the cycle. This method ensures the bluing doesn't interact with detergent residues.
  4. Complete the Cycle: Allow the washer to finish its complete wash, rinse, and spin cycles.

  5. Dry as Usual: Remove your items and dry them according to their fabric care instructions. Inspect for evenness; if you notice any blue streaks, you likely used too much bluing or didn't dilute it sufficiently.

Bluing Dilution Guide

The exact amount of bluing can vary slightly by brand and the size of your load. This table offers a general guideline:

Wash Load Size Bluing Amount (Approx.) Dilution Water
Small A few drops 1 Quart Cold Water
Medium 1/8 Teaspoon 1 Quart Cold Water
Large 1/4 Teaspoon 1-2 Quarts Cold Water

Remember: Always err on the side of using less bluing initially.

Tips for Best Results and Avoiding Stains

  • Always Dilute: This cannot be stressed enough. Undiluted bluing will cause blue spots or streaks that are difficult to remove.
  • Cold Water is Key: Use cold water for diluting bluing.
  • No Bleach: Do not use bluing with bleach. The combination can lead to yellowing or permanent stains.
  • Wash Separately: For best results, wash only white items that you intend to blue.
  • Clean Washer: Ensure your HE washer tub is clean and free of detergent buildup before bluing, as residue can react with the bluing.
  • Pre-Soak Stains: If your whites have yellow stains, pre-treat them before bluing. Bluing enhances whites; it doesn't remove stains.
  • Frequency: Bluing is not usually needed for every wash. Use it every few washes, or when you notice your whites starting to dull.
  • Check Manufacturer Instructions: Always refer to the specific bluing product's instructions, as formulations can vary slightly. For more information on fabric care, you can consult resources like The Spruce.

By following these steps, you can safely and effectively use bluing in your HE washer to keep your whites looking their brightest.
