Why doesn't Koh use bleach?

Sensitive Laundry Liquid and Stain Remover are bleach-free. The formulas contain no chlorine bleach, no oxygen bleach, and no optical brighteners. Bleach can weaken fibres and damage fabrics over repeated washes, especially delicate weaves and synthetic blends. Koh's enzyme and surfactant approach cleans effectively while being gentler on clothes. Note that Koh helps protect whites from dulling over time but isn't a fix for already damaged or permanently greyed fabric.

✓ 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.

Prevention not restoration

How does Koh help keep whites bright?

Used regularly, Sensitive Laundry Liquid and Stain Remover help lift the everyday soils, sweat residues, and surface build-up that gradually dull white fabrics. The formulas don't contain optical brighteners, which mask dulling cosmetically. Instead, they help remove the build-up that causes the dulling in the first place, particularly on cotton and similar fabrics. Whites stay looking fresher and newer for longer when used as part of a regular wash routine.
