How to Keep White Laundry Bright

Follow these proven laundry tips to prevent white clothes from turning grey:

1. Separate White Clothes from Colours

Always wash white garments on their own. Mixing colours can transfer dyes and dull your whites over time.

2. Use the Right Detergent for Whites

Choose a detergent specifically designed for white fabrics. These formulas contain bleaching agents (e.g., sodium percarbonate) that help maintain brightness.

3. Measure Detergent Correctly

Using too much detergent can cause residue buildup and make white clothes appear grey. Always:

  • Adjust the amount based on water hardness and soil level
  • Follow the detergent manufacturer’s dosage instructions for best results

This ensures effective cleaning while preventing limescale and soap residue from dulling your whites.

4. Store Detergent Properly

Keep detergent containers tightly closed. Exposure to air can reduce the effectiveness of whitening agents.

5. Run a Maintenance Wash Regularly

Detergent residue, limescale, and dirt can build up inside your washing machine over time and transfer onto clothes, making whites appear dull or grey.

To prevent this:

  • Run a maintenance wash (empty cycle) at least once a month
  • Use a high temperature cycle (60–90°C)
  • Add a washing machine cleaner, descaler, or white vinegar
  • Follow the detergent or appliance manufacturer’s recommendations for cleaning and maintenance
  • For best results, use recommended care and maintenance products available in our webshop, specially designed to remove residue, prevent limescale buildup, and keep your washing machine performing at its best

Common Causes of Grey or Dull Whites

  • Incorrect detergent dosage → leads to limescale and soap scum buildup
  • Hard water deposits → leave a grey film on fabrics
  • Residue accumulation → dulls brightness over time

How to Restore Grey White Clothes

Remove Limescale Build-Up

Wash towels and white fabrics with:

  • A small amount of citric acid powder, or
  • White vinegar (instead of detergent)

This helps dissolve mineral deposits and restore brightness.

Deep Whitening Treatment

For heavily greyed towels:

  1. Soak in water with 100 - 200 ml chlorine bleach for 2 hours
  2. Wash in the machine at the highest allowed temperature (check care labels)

Safety Tip

Never mix chlorine bleach with other cleaning products, as this can produce dangerous toxic fumes.
