Heritage Park Silk & Wool Fragrance Free, Hypoallergenic, pH-Neutral Laundry Detergent – Dermatologist-tested, Sensitive Skin-Friendly, Enzyme-Free, Concentrated Up to 64 loads (32 fl oz)

I love cashmere sweaters, but they are a delicate wool. While dry cleaning is recommended, it is expensive, and dry cleaning leaves a chemical smell. This product cleans well, and leaves the cashmere in great shape. I noticed how much better it is on the wool over regular laundry detergent. I like that after cleaning my sweaters smell clean, but not scented. I also like how concentrated it is. The small bottle does as many loads as the huge container of standard liquid laundry detergent. That makes so much more sense for the environment. It is so much more efficient to have a smaller bottle of concentrated detergent over a giant bottle that does the same number of loads. I am further impressed that I can buy a refill for the bottle instead of tossing more plastic waste in the landfill. An added bonus is that it is an American product. Highest praise!

Cleans well, and the conditioner in this soap made my wool socks so soft -- definitely way better than Woolite! I would not use this on silk because the conditioner would leave a residue on it, but highly recommend it for washing wool and cashmere clothing!

Cleans well best part it’s fragrance free

It worked really well on my cashmere sweaters and woven silk blouses, less well on the knitted silk noil sweaters and silk jersey tops, which still dried kind of stiff and not as soft as I would have liked. But they're clean, and the fibers don't appear to have been damaged, it just doesn't give the finish I would get from having them dry cleaned. I was nervous that the scent would be too powerful but it's nice and subtle. There larger bottles are definitely better value than the small one, but I wanted to try it out before I invested in a big one.

Works great! Gentle on materials & love that it’s fragrance free

I used this on a water stain on a silk/wool blend pain in the neck beautiful sofa.. thank goodness, it did the job beautifully!! Highly recommend!!

Not sure how to assess this. I used it for a gentle cycle of two cashmere sweaters and one merino/cotton blend. All sweaters were protected by sweater bags; I set the machine to "Gentle" and cold water. The cashmere sweaters didn't look bad, but the other one really was a disappointment -- wrinkled and without any shape. No shrinking with any, just not great shape retention. I've laundered cashmere this way before, with a less expensive soap product, and the results weren't that much different. So to my original statement: I'm not sure how to assess this product. But I'll say this: It is expensive; one half bottle for the laundry load.

It works very well for silk and wool fabrics
