Do I need bleach whiteners with Sensitive Laundry Liquid?Updated 20 hours ago

TL;DR: Sensitive Laundry Liquid is built to wash whites without a separate bleach booster. Its surfactants hold soil in the wash water so it rinses away instead of settling back onto the fabric. The formula has no chlorine bleach, no oxygen bleach and no optical brighteners. Whites that are already dull want a one off whitening treatment first.

Do I need bleach whiteners with Sensitive Laundry Liquid?

Koh Sensitive Laundry Liquid is built to wash whites on its own, without a separate bleach booster. Whites dull when soil suspended in the wash water settles back onto fabric during the cycle, and the surfactants in the formula hold that soil in the water so it rinses away. The formula has no chlorine bleach, no oxygen bleach and no optical brighteners.

Whites dull because soil suspended in the wash water settles back onto the fabric during the cycle. Regular washing with Sensitive Laundry Liquid is what keeps that from building up, so a bleach booster is not part of the routine. If a white item is already dull or yellowed with age, give it a one off treatment with a dedicated whitening product, then keep it that way with regular washes.

✓ How Sensitive Laundry Liquid handles whites

The surfactants in the formula hold soil in the wash water so it rinses away with the water rather than settling back onto white fabric. That is what keeps whites looking their best load after load.

How do I keep whites looking their best?

Wash whites separately from coloureds where you can, and do not overload the drum, because fabric needs water moving around it to rinse properly. Air dry in sunlight when the weather allows. Follow the garment care label first, every time. A normal load takes 24 mL of Koh Sensitive Laundry Liquid, which is 6 pumps.
