How do I keep whites bright without bleach?Updated 2 hours ago
TL;DR: Sensitive Laundry Liquid and Stain Remover are bleach-free. They help lift the everyday build-up and surface dulling that can make whites look grey, used as part of your normal wash routine. Pre-treat with Stain Remover, then wash with Sensitive Laundry Liquid.
Why doesn't Koh use bleach?
✓ Bleach-free formulas
Traditional whitening products usually contain chlorine or oxygen bleach to whiten fabrics quickly. Bleach can weaken fibres and damage fabrics over repeated washes. Sensitive Laundry Liquid and Stain Remover clean effectively without bleach.
⚠ Set realistic expectations
Koh helps protect whites from dulling over time but isn't a fix for already damaged or permanently greyed fabric. Severe yellowing from heat, age, or previous bleach use generally can't be reversed with a wash routine.
How does Koh help keep whites bright?
✓ Lifts everyday build-up
Used regularly, Sensitive Laundry Liquid and Stain Remover help lift the everyday soils, sweat residues, and surface build-up that gradually dull whites.
Without optical brighteners that mask dulling cosmetically, the formulas help remove the build-up that causes the dulling in the first place. Whites stay looking fresher for longer as part of a regular wash routine.
How do I use them on whites?
