Best Laundry Detergent for Wool

Why Wool Needs a Specialist Detergent

Wool fibers have a unique structure — they're covered in microscopic scales that interlock when exposed to heat, agitation, and alkaline detergents, causing felting and shrinkage. Standard laundry detergents are too alkaline and too aggressive for wool. A specialist wool detergent is formulated to clean effectively at the correct pH without damaging the fiber structure.

What to Look for in a Wool Detergent

• Neutral or slightly acidic pH — wool fibers are damaged by alkaline detergents. Look for pH-neutral or wool-safe formulas.
• No enzymes — proteases (protein-digesting enzymes) in standard detergents attack wool fibers, which are protein-based.
• Gentle surfactants — mild cleaning agents that remove dirt without stripping the natural lanolin from wool.
• Suitable for cold water — wool should always be washed in cold or lukewarm water.

Top Recommendation: Outback Gold Wool Wash

Outback Gold Wool Wash is a plant-based, pH-neutral liquid detergent specifically formulated for wool, cashmere, silk, and other delicate natural fibers. It's HE compatible, free of harsh enzymes, and gentle enough for hand washing. It also works well for sheepskin and baby items.

How to Wash Wool Correctly

1. Use cold or lukewarm water — never hot.
2. Add a small amount of wool wash detergent.
3. Hand wash by gently squeezing — don't agitate, scrub, or wring.
4. If machine washing, use the wool or delicate cycle with cold water and place in a mesh laundry bag.
5. Rinse thoroughly in water the same temperature as the wash water — temperature changes cause felting.
6. Press water out gently — never wring.
7. Lay flat to dry — never hang wet wool.

Can You Use Regular Detergent on Wool?

Technically yes, but it's not recommended. Regular detergents are too alkaline and contain enzymes that damage wool fibers over time. Even one wash with a harsh detergent can cause noticeable felting or shrinkage. A specialist wool wash is a small investment that protects a much larger investment in wool clothing.

Final Thoughts

Outback Gold Wool Wash is the best all-around wool detergent — plant-based, pH-neutral, enzyme-free, and effective for all delicate natural fibers. Combined with cold water and gentle handling, it keeps wool soft, shaped, and undamaged wash after wash.
