Specialty Wash — Cashmere + Wool Garments
Specialty Wash — Cashmere + Wool Knitwear
This listing is for our Specialty Wash treatment for cashmere, wool, alpaca, mohair, angora, yak, camel, and other natural animal-fiber knits: a more dimensional dye process intended to transform the overall color of an item with layered, variegated, or multi-tonal effects.
Specialty Wash is not a solid or factory-even dye treatment. Knitwear may dye with movement, contrast, mottling, lighter areas, darker areas, color shifts, resist marks, tonal variation, or uneven dye uptake. Natural animal fibers can be beautiful candidates for this process, but they are also more delicate and less predictable than cotton, silk, or other woven fabrics.
Introductory pricing includes a prepaid inbound shipping label and return shipping within the U.S.

Choose the item type that best matches your piece, then choose your color family.
Color names are intended as general color families, not exact color guarantees. Specialty Wash results will vary depending on the original color, fiber content, knit structure, yarn blend, prior wear, and the way the dye moves through the piece.

Best candidates
This service is best for cashmere, wool, alpaca, mohair, angora, yak, camel, and natural animal-fiber knit blends.
Best results are typically achieved on high natural animal-fiber content. 100% cashmere, 100% wool, or high-content blends are usually the strongest candidates.
Blends with nylon, acrylic, polyester, spandex, or other synthetics may dye lighter, less evenly, or less predictably. Synthetic fibers may not absorb dye the same way as the natural fiber content.
Cotton, linen, rayon, viscose, silk, and silk velvet should be submitted through the appropriate listing.
Knitwear risks + expectations
Cashmere, wool, alpaca, mohair, angora, and other animal-fiber knits can behave very unpredictably during overdyeing and washing. Even when fiber content appears similar, two sweaters may react completely differently.
Shrinkage, texture shifts, relaxation, tightening, stretching, seam stress, thinning, pilling, surface fuzzing, distortion, uneven dye uptake, resist marks, water marks, and color irregularities are all possible during the dye process.
Some pieces may become softer after processing, while others may become denser, fuzzier, more textured, slightly felted, or more fragile. Lightweight, loosely knit, vintage, heavily worn, or previously damaged sweaters are especially vulnerable to tearing, seam separation, fiber breakage, and unexpected structural changes during washing and handling.
Cashmere and wool often have a mind of their own during overdyeing. Results can shift dramatically depending on yarn structure, prior wear, coatings, shrinkage history, detergent residue, previous cleaning methods, blending fibers, and invisible damage accumulated over time.
Because of this unpredictability, Riverside Tool & Dye cannot guarantee exact sizing retention, texture retention, softness retention, or structural outcome on knitwear pieces.
Items with holes, weak areas, thinning elbows, stretched ribbing, dry rot, moth damage, excessive pilling, or unstable seams may be declined after review.
Important notes
Specialty Wash is intentionally variable. Color placement, contrast, saturation, patterning, and overall effect will differ from piece to piece.
Overdyeing can darken, shift, or soften an existing color, but it cannot make a dark item light. Stains may be disguised, softened, or transformed, but they may not disappear completely.
Thread, zippers, elastic, labels, buttons, embroidery, linings, and synthetic trims usually do not dye and may remain their original color.
Some knitwear may not be accepted after review, especially if the fiber content, construction, condition, or prior treatment makes the piece too risky to dye.
By purchasing this service, you understand that unexpected results are possible and are part of the nature of overdyeing. Knitwear dyeing carries a significantly higher level of variation and risk than standard garment overdyeing.
Color references
For examples of a specific colorway, search the color name on our website to see prior pieces dyed in that color family. Final results will still vary by fabric, garment construction, original color, and dye treatment.
