Washing a down jacket or comforter with regular laundry detergent strips the natural oils from feathers, leaving them flat, clumpy, and cold. A dedicated down detergent removes grime and body oils while preserving the delicate structure that traps warm air — so your gear stays lofty through many wash cycles.

How To Choose The Best Down Detergent
Down is a natural fill that clumps and loses its insulating air pockets when washed with standard laundry soap. Choosing the right cleaner depends on a few things specific to how you plan to use your gear.
Cleaning only or cleaning plus waterproofing
Some down detergents only wash the feathers. Others are a 2-in-1 that also renews the DWR (durable water repellent) coating on the outer fabric — this extra step saves you time if you are washing a waterproof jacket or sleeping bag.
Bottle size and number of washes per bottle
Bottles range from 10 fl oz to 64 fl oz. The product data tells you how many washes you get per bottle (for example, Granger’s states 12 washes). If you wash multiple jackets, pillows, or comforters every season, a larger concentrated bottle gives you much better value per load.
Scent or fragrance-free for sensitive skin
Several brands offer unscented options. If you have allergies or plan to use the items for camping in bear country, a fragrance-free choice is the safer pick.

In‑Depth Reviews
1. Granger’s Down Wash – 10 fl oz (300ml)
The reliable cleaner that keeps down gear lofty without any buildup over years of use.
It keeps your down jacket’s feathers fluffy — you get the most washes per bottle on this list. The 10 fl oz (300ml) bottle gives you 12 washes, which easily lasts a year or more if you wash one or two jackets each season. The concentrated formula removes dirt and odor while restoring the loft (the air-trapping fluff that keeps you warm), and it is safe for membranes like Gore-Tex, eVent, and Pertex.
Buyers report that this down detergent delivers “consistent quality over years” and “preserves down items through frequent washes without buildup.” It is cruelty-free and PFC-free (no fluorocarbons that harm the environment), and Bluesign approved, certifying the manufacturing process is eco-responsible. The only downside a few reviewers mentioned is the mild scent, which fades after drying. At 11.3 ounces the bottle is slightly lighter than the Down Wash and Repel (12.35 ounces), but the real advantage is the sheer number of washes you get for the money. If you want a 2-in-1 that also waterproofs, you need the Down Wash and Repel below.
What stands out
- Concentrated — you get 12 washes per 10 fl oz bottle
- PFC-free, cruelty-free, and safe for Gore-Tex
- Owners mention it keeps down fluffy with no residue even after frequent washes
The catch
- Some buyers wish the smell were stronger or more pleasant
- Only cleans; does not add waterproofing
Best for most people: If you need a straightforward cleaner that restores loft and works on any insulated gear, this is the one to buy.
Look elsewhere if: You want a single product that also renews DWR waterproofing — that 2-in-1 capability belongs to the Down Wash and Repel below.
2. Down Wash and Repel (10 fl oz/300ml)
A single bottle that cleans and re-waterproofs your down gear in one wash cycle.
Grangers claims this is the only aftercare brand offering a 2-in-1 clean and re-waterproof formulation in one bottle — saving water and energy. It removes dirt and odors while restoring the original DWR (durable water repellent coating) on down jackets and sleeping bags. One reviewer noted it “restored down coat’s original color and cleaned collar/pockets well,” and another said the waterproofing came back like “night and day” on expensive ski jackets.
Unlike Granger’s standard Down Wash above, the provided specifications here do not state a washes-per-bottle figure. It also requires a careful drying process (low-heat with tennis balls for hours) and a pre-wash to remove detergent residue, as one buyer explained. The bottle is 12.35 ounces versus the plain Down Wash at 11.3 ounces, and the dimensions are 8.07 x 1.97 x 1.97 inches, so check your laundry cabinet space. This one is for the Gore-Tex jacket owner who wants to clean and re-waterproof in a single load.
Why buy it
- One product cleans and restores water repellency at the same time
- PFC-free and uses a 100% recycled plastic bottle
- Real reviewers saw restored DWR on jackets that were years old
Before you grab it
- The provided specifications here do not state a washes-per-bottle figure
- You must dry thoroughly with tennis balls or wool balls to avoid clumping
Perfect for: One-bottle solution owners of Gore-Tex down jackets who want to clean and re-waterproof in a single load.
skip it if: You wash down gear frequently and would rather choose a dedicated cleaner than a 2-in-1 wash-and-reproof formula.
3. HEITMANN Down Wash Care 250g
A gentle German formula that uses lanolin to renew down without dyes or fragrances.
HEITMANN is made in Germany and includes lanolin (a natural wool wax) that renews the down’s natural coating to keep feathers soft and voluminous. It is dye-free, fragrance-free, and free of harsh chemicals — a strong choice if you have sensitive skin or allergies in the family.
Customers note that “HEITMANN down wash restores down jackets/pillows to like-new condition” and praise the gentle cleaning that prevents clumping. The 250g bottle is compact — dimensions are 2.01 x 2.28 x 6.1 inches — so it tucks into a laundry caddy easily. The packaging uses 92% recycled material. Unlike the 300ml bottles from Grangers, the 250g weight is a solid measure, and the color protection feature helps keep dark outer fabrics from fading. The biggest trade-off is availability: because it is imported, you may pay a premium compared to domestic brands, and some users said it is harder to find refills. Go for this one if scent bothers you or someone in your home has allergies.
Why it stands out
- Lanolin formula restores natural down coating without synthetic additives
- Dye-free, fragrance-free, and harsh-chemical-free — safe for sensitive family members
- Color protection keeps the outer fabric bright
What to consider
- Imported product — can be pricier than domestic alternatives
- No DWR waterproofing — this is a cleaner-only formula
Best fit: Households with allergies or sensitivity to scents who want a gentle, natural-feel down cleaner.
Not ideal if: You are looking for a 2-in-1 waterproofing solution or need the largest bottle for frequent use.
4. Nikwax Down DUO-Pack, 300ml
The two-step system that revives even 15-year-old down sleeping bags and jackets.
This DUO-Pack includes a separate Down Wash (cleaning) and Down Proof (waterproofing) treatment — so you do both steps yourself, in order. The Down Wash cleans without optical brighteners or added scent, and the Down Proof adds water repellency to both the down fill and the outer fabric. Together, they are designed for gear with down, down blends, or Nikwax Hydrophobic Down.
One reviewer shared a real-world process: “I then placed the bag in the dryer and did 4 drying cycles on very low heat with tennis balls” — and the sleeping bag came back to full loft. Another buyer called it a “standout” for a stained 8-year-old jacket that dry cleaners could not fix. The Nikwax system is PFAS-free (no persistent chemicals) and water-based, so it is eco-conscious. The catch, as several reviewers point out, is the time investment: you must wash, then proof, then dry thoroughly with low heat cycles — plan for half a day. But for expensive gear like Arc’teryx or Patagonia, the results match the price. If you just wash everyday pillows, the Granger’s Down Wash is faster and costs less per load.
What makes it elite
- Two separate treatments ensure thorough cleaning and then waterproofing without compromising either
- PFAS-free and unscented — no chemicals or perfumes left on gear
- Reviewers report dramatic revival of down items up to 15 years old
The trade-off
- Takes multiple wash and dry cycles to complete — not a quick wash solution
- Higher upfront cost than single-bottle alternatives
Reach for this if: You have expensive down sleeping bags or premium ski jackets that need a full restoration — the two-step process gets results that single products cannot match.
Skip it for: Regular seasonal maintenance of everyday pillows and comforters, where a single wash formula is faster and cheaper.
5. Le Blanc Green Meadows Downwash – 64 oz
The big bottle for households that wash pillows, comforters, and jackets in bulk.
At 64 ounces and a 4-pound package, this concentrated cleanser is the biggest bottle on the list — and its neutral pH formula is free of bleach, enzymes, phosphates, and sulfates. It works in cold water and is safe for cotton, silk, and other down-filled fabrics.
Buyers noted that it is “a better deal per ounce than the products by Nikwax and Gear Aid” and that it handled sunscreen stains and even pet urine on a down comforter. The Green Meadows scent is strong right out of the wash, which some reviewers loved and others found too heavy — one specifically asked the manufacturer for an unscented version. In 2025, the brand does offer an unscented option, so check that if the floral-green profile is not for you. This product is purely a cleaner — it does not add DWR waterproofing — so you would need a separate spray-on proofing if your jacket needs it. Buy the big bottle if you run a load of pillows and comforters every month.
Why buy the big bottle
- Largest capacity (64 oz) — best value per load for frequent washers
- Neutral pH and free of harsh additives, safe for delicate down fabrics
- Buyers confirm it removes sunscreen, body oil, and stubborn stains
One thing to know
- No waterproofing treatment — this is a cleaner only
- Strong green-floral scent remains on washed items for a while
Ideal for: Large households or anyone who regularly washes multiple pillows, comforters, and jackets — the 64 oz bottle stretches far.
Not for you if: You dislike scented products or need a combined clean + DWR solution.
Understanding the Specs
Loft Restoration
Loft is the ability of down to expand and trap body heat. A down detergent with loft restoration pulls out dirt and oils that compress the feathers, then lets them puff back to full volume during drying. A product without this claim may clean but leave feathers flat.
2-in-1 vs Separate Wash and Proof
A 2-in-1 product cleans and adds DWR (durable water repellent coating) in one step — saving time and water. A separate wash and proof system lets you treat the waterproofing more thoroughly, but requires two cycles. If your jacket or sleeping bag already has good water repellency, a cleaner-only product is enough.
