Woolite Darks Defense Liquid Laundry Detergent - Protects Color

Our review of Woolite Darks Defense finds it best suited to anyone who wants to keep dark clothes looking newer, longer; the single biggest reason to buy is its protective formula that claims to prevent fading and pilling for up to 20 washes while gently removing everyday soils. The reviewer tested it on a mix of jeans, synthetic leggings and a favorite blouse and found that it cleaned effectively without the harshness of bleach or optical brighteners, leaving garments with preserved color and a mild, pleasant scent.

Key Features

• Color protection: The formula is designed to protect dark and deep colors from fading for up to 20 washes, helping garments retain their original shade.
• Pilling and stretch resistance: It helps reduce pilling for up to 20 washes and minimizes stretching for up to 6 washes, which is useful on blends and synthetics.
• Gentle cleaning: The detergent uses a combination of ingredients to remove stains and soils without the harshness of bleach or phosphates, so delicate dark fabrics stand up better over time.
• HE and regular compatible: It works in both HE and conventional washers, making it convenient for mixed household machines.
• Free from harsh additives: The formula is free from optical brighteners, phosphates, bleach and dyes, reducing the risk of residue or unexpected fading caused by brighteners.

Who It's For

This product is aimed at people who own a wardrobe of dark garments - jeans, leggings, synthetic athletic wear and blouses - and who wash those items regularly but want to preserve color and fabric integrity. It is also a good option for households that use both HE and standard washers and prefer detergents without optical brighteners or bleach.

Shoppers who routinely need heavy-duty stain removal for greasy or oil-based stains may want to supplement with a targeted prespot treatment, and those who buy large quantities for commercial laundry should note this listing is per-pack information and packaging may vary.
