Q: Is Bath Fiber Wash safe for hand-dyed fiber?

A: Yes! Bath Fiber Wash is safe and gentle – even for hand-dyed, saturated colors. As with any fiber wash, you may see excess dye in the water or experience color transfer in your handknits if the dye, itself, has been over-saturated. In cases of over-saturated fiber, even a soak in plain water would cause color to permeate the water and potentially bleed in the fabric. However, this would not be caused by the fiber wash.

Q: Is Bath Fiber Wash safe for delicate fibers like silk?

A: Yes! Bath Fiber Wash is as gentle as baby shampoo and is safe for silk and other delicate fibers.

Q: Can you use this fiber wash on acrylic yarn? cotton? blends?

A: Absolutely.

Q: How strong is the scent?

A: The fragrance in the scented options leave your handknits with a light, fresh scent. They are not overpowering but leave a lingering freshness. Two of our scent options are created with organic essential oils, which help to provide moth protection for as long as the scent remains. To this end, the Organic Lavender and Pacific Northwest options hold their scent a little longer in order to extend the moth protection in your knits.

Q: What exactly does this fiber wash do?

A: Bath Fiber Wash is a bit like using a conditioning shampoo – on your handknits! The natural coconut-based cleanser removes any lingering dirt, debris, and/or residue. The vegetable glycerin gently softens and conditions the fibers. Your projects will block beautifully and be left with a fresh, clean scent.

Q: Will this fiber wash help with moths and other pests?

A: Any time you handle, wash and refresh your knits, you are helping to ensure that they don’t fall prey to moths and other wool-harming critters (like carpet beetles). Our Organic Lavender wash provides an extra layer of protection – we use QAI Certified Organic Lavender essential oil (Lavandula angustifolia), which has been found to deter moths. (It’s the natural chemical compounds in lavender essential oil which studies have found to be a moth deterrent for as long as the scent remains. Our lavender contains the following primary constituents: Linalool: 30.84%, Linalyl acetate: 30.65%, Camphor: 0.19%.) Our Pacific Northwest scent is a proprietary blend that includes organic Himalayan Cedar Essential Oil, containing β-Himachalene: 34-46% and α-Himachalene: 10-20%. Cedar oil has been found to have protective properties against moths and other pests and is why handknits are often stored in cedar chests.

We recommend washing/re-blocking your knits once every 6 months to refresh and protect them.
