Use Instructions

Use Heritage Park Silk & Wool detergent for your favorite washable protein-based clothing and home textiles. Great for pure and blended silk; sheep, merino, and Shetland wool; mohair and angora cashmere; alpaca, camel, llama and vicuña; feather/down, fur, and more!

Heritage Park laundry detergents are concentrated so you use less and waste less; it is also biodegradable and safe for septic and greywater systems.

Effective in all water temperatures, from cold to hot, our liquid laundry detergents can be used in standard or high-efficiency (HE) washing machines. It's also perfect for hand-washing clothing, linens, and other delicate fabrics.

For tough, set-in stains, we recommend using our All-Purpose detergent to pre-treat by diluting with little water and applying directly to the stain, rubbing in gently. With protein-based fabrics like silk, wool, and cashmere, use our All-Purpose detergent very sparingly and only as needed for stain treatment as the enzyme-based formula can damage these fabrics if used too often.

Important Note: Always follow the fabric manufacturer's washing instructions.

No Harsh Chemicals or Irritants Found in our Laundry Detergent

Regular laundry detergent is packed with chemicals, compounds, and dangerous ingredients that can trigger allergies, provoke reactions, and irritate delicate skin. We make our concentrated, clear laundry detergent without these harmful ingredients. You won’t find any of these problematic ingredients in Heritage Park Laundry Detergents:

No dyes: The dyes used to color a detergent or cleaning product serve absolutely NO purpose and are a source of skin irritation and allergies.

No sulfates: These chemical compounds are used to create foam in laundry products (and household cleaning and personal care products like dish soap, body wash, and shampoo). Sulfates irritate allergies, eczema, and other skin conditions.

No phosphates: Used to soften hard water, phosphates are toxic chemicals dangerous for people and the environment. Most reputable detergent manufacturers have stopped using phosphates.

No chlorine: This highly reactive chemical element is used to disinfect and sanitize but triggers irritation and contact dermatitis.

No bleach: Oxygen and chlorine bleach can irritate the skin. Bleach should be used only following the manufacturer’s directions and in small quantities, never as an ingredient in detergent.

No optical brighteners: These synthetic chemicals remain on clothing and laundry to absorb UV light and make items appear brighter. Along with irritating skin, these compounds are NOT biodegradable.

Heritage Park is making an effort to reduce plastic waste

I'm glad that this formula for wool and silk exists. I just wish I could get a simple soap or soap flakes for these protein-based items. Also, I'd give five stars for a plastic-free version!
