## Quick Answer

Wash your horse blanket at **30 °C (86 °F) maximum** on a delicate cycle, with a soap-free technical cleaner (Nikwax Tech Wash, Bucas Rug Wash, or Nikwax Rug Wash), **never fabric softener**, fasteners closed, after dry brushing. Dry flat in the shade — **never tumble dry**. For a heavy turnout, Waldhausen recommends at least 12 kg of capacity, which a Speed Queen 18 kg (40 lb) laundromat washer covers without strain. For a Rambo or Rhino under warranty (\< 3 years), use a professional: washing outside the instructions voids the waterproof warranty.

## At a glance

- Temperature: 30 °C delicate cycle, never higher (40 °C tolerated by Waldhausen on a very dirty blanket outside warranty).
- Detergent: Nikwax Tech Wash, Bucas Rug Wash, or Nikwax Rug Wash — no household detergent, **no fabric softener**.
- Dry brush before machine washing, with all fasteners closed.
- Extra rinse to remove residue.
- Dry flat in the shade, never tumble dry, never in direct sunlight.
- Nikwax Rug Proof reproofing only if the DWR is worn **and** the blanket is no longer under the 3-year Rambo / Rhino warranty.
- Blanket too heavy for a household washer → 18 kg laundromat washer.

The Nikwax Tech Wash + TX.Direct combo

handles both washing (Tech Wash, soap-free, without residues that damage water
repellency) and reproofing (TX.Direct). Originally designed for membrane
clothing, it can also be used on horse blanket shells, as long as the blanket is
not under its original warranty (see edge cases).

## Step-by-step method

### 1. Prepare the blanket (dry brushing)

Take the blanket out, shake it, and brush firmly to remove hair, dried mud, and manure. If needed, hose it down — water removes much of the surface dirt. **The cleaner the blanket goes into the washer, the better the DWR can recover**, because DWR must be applied to clean, still-damp fabric: if dirt is embedded, the DWR sticks to the dirt instead of the textile.

### 2. Close all fasteners

Close every buckle, belly strap, Velcro tab, and zipper. This is the explicit instruction from Kramer Equestrian and Bucas. Open Velcro in the drum catches on the membrane, on the laundromat’s included detergent system, and even on several points of the blanket itself. It is the first cause of tearing.

### 3. Choose the right detergent (and ban fabric softener)

Nikwax states it clearly: **conventional detergents leave residues that damage water repellency**. Bucas and Kramer add that fabric softener clogs the pores of the DWR membrane and neutralizes water repellency. On a waterproof shell:

- ✅ Nikwax Tech Wash (universal membrane cleaner, the easiest to find — kit with TX.Direct if DWR needs restoring)
- ✅ Bucas Rug Wash (official Bucas cleaner, dosage shown on the bottle)
- ✅ Nikwax Rug Wash (direct equivalent for turnouts)
- ❌ Standard household detergent
- ❌ Powder detergent (residue in pockets and seams)
- ❌ Fabric softener
- ❌ Bleach

On a fleece or mesh sheet without DWR, a gentle liquid detergent works. If you use the same washer afterward for a DWR turnout, watch out for fabric softener residue that may have remained in the drum.

### 4. Run the cycle

- Program: **delicate** (Kramer, Bucas, and Waldhausen all call for a delicate cycle).
- Temperature: **30 °C max** on a delicate cycle (Bucas, Kramer). You can go up to **40 °C delicate cycle** on a very dirty blanket that is not under a waterproof warranty (Waldhausen). For a Rambo / Rhino turnout, Horseware explicitly asks for **“cool”** water.
- Spin: **low** (Kramer Equestrian recommends the gentlest spin cycle available).
- Rinse: add an **extra rinse** (Bucas and Waldhausen instruction to remove all detergent residue).

> **Warning:**
> - **Do not use 60 °C (140 °F) or 90 °C (194 °F)** on a horse blanket, even if your Speed Queen laundromat offers those temperatures. Equestrian manufacturers (Bucas, Kramer, Horseware, Waldhausen) cap washing at 30-40 °C (86-104 °F) to preserve water repellency.

### 5. Reproof if needed (glass-of-water test)

Simple test after the cycle: pour a little water onto the still-damp shell.

- The water **beads and rolls off** → DWR is still active, no need to reproof.
- The water **spreads or soaks in** → DWR is worn and needs restoring.

Two methods (Nikwax sources):

- **Wash-in / machine additive**: immediately run a cycle with **Nikwax Rug Proof** or **Nikwax TX.Direct Wash-In** without taking the blanket out of the drum, with no intermediate drying — Rug Wash and Rug Proof can be run as two consecutive machine cycles without drying between them.
- **Spray**: Nikwax TX.Direct Spray-On on the still-damp blanket after washing. Follow the bottle instructions for spraying, then let it soak in before drying.

**Produit recommandé**

### 6. Dry flat in the shade

Lay the blanket over a rail, drying rack, or hang it in the shade — the “shaded location” instruction is explicit from Kramer Equestrian, Horseware, and Waldhausen. Do not fold it before it is fully dry (see the edge case “Blanket stored wet all summer”).

> **Warning:**
> - **No tumble dryer.** Kramer Equestrian, Bucas, Horseware, and Waldhausen all say it: heat can damage the waterproof membrane. Air drying remains the only recommended option.

## Edge cases

### Rambo or Rhino turnout under original warranty (\< 3 years)

This is the classic trap. **Washing outside Horseware’s instructions voids the waterproof warranty** on Rambo and Rhino turnouts. And **reproofing a Rambo / Rhino turnout within its first 3 years of use also voids the original warranty**. In practice:

- Read the model’s care label.
- If it requires Rambo Wash and a specific cycle, follow it exactly.
- If the blanket needs a true deep clean, **Horseware recommends sending it to a professional equipped for horse blanket washing** — not a self-service laundromat.
- An 18 kg laundromat washer remains useful for the other blankets in the stable (sheets, fleeces, blankets outside warranty) while the Rambo is away at the professional service.

### Blanket from a sick horse or a horse under veterinary treatment

If the blanket comes from a horse with mange, dermatitis, ringworm, or another condition, or if the horse is under treatment, **ask your veterinarian for advice** before washing. Animal disinfection protocols fall outside the sources for this article, and a standard wash may not eliminate some pathogens. Do not bring a potentially infectious blanket into a public laundromat without veterinary advice.

### Household washer too small

A canvas sheet or lightweight fleece usually fits into a standard household washer without difficulty. A padded winter turnout is another matter: Waldhausen recommends **at least 12 kg** for heavy rugs, which few household washers reach. That is exactly where an **18 kg washer** (available at Speed Queen Blagnac Andromède and Toulouse Croix-Daurade) fits: the blanket moves freely, and the standard wash cycle lasts about 30 minutes.

> Planning tip: the 07:00–22:00 opening window at Speed Queen laundromats lets you schedule the wash outside stable hours. The Speed Queen loyalty card offers up to 20% off all washes.

### Torn blanket or damaged straps

A torn blanket often comes out of the washer worse than it went in: the tear grows, sealed seams give way, and the membrane peels. **Go to a saddler first**, have it repaired, then wash it.

### Blanket stored wet all summer

A late-summer classic: you find the blanket in its bag, forgotten since April. Mold, odors, and sometimes stains that have penetrated the membrane. The rule: **pre-soak** in a tub of cold water + Rug Wash (Kramer Equestrian recommends pre-soaking very dirty rugs before machine washing), then run a 30 °C delicate machine cycle **with an extra rinse**. If the odor remains, run another cycle. For the next season, always store the blanket **completely dry**, in a breathable bag, not an airtight one.

## Mistakes to avoid

1. **Pouring in fabric softener**. This is the first mistake owners make when they are not used to DWR shells. Fabric softener clogs the pores of the membrane and neutralizes water repellency — Bucas, Nikwax, and Kramer all say so.
2. **Putting the blanket in the tumble dryer** to save time. Kramer, Bucas, Horseware, and Waldhausen ban tumble drying; heat can damage the waterproof membrane.
3. **Using the laundromat’s included detergent on a DWR shell**. Speed Queen does include detergent and fabric softener in the wash price, but that detergent is designed for household laundry, not waterproof shells. **Bring your Nikwax Tech Wash or Bucas Rug Wash** and choose a program that does not add fabric softener — ask the on-site team if you are unsure.
4. **Always washing at 40 °C or 60 °C**. Above 30 °C, water repellency may be affected depending on the brand; Bucas and Kramer set the limit at 30 °C max, and Horseware asks for cold water.
5. **Spraying DWR (Rug Proof, TX.Direct) onto a dirty or dry blanket**. DWR must be applied to clean, still-damp fabric; otherwise it sticks to dirt or fails to penetrate the textile. The order is: dry brushing → washing → spray on the still-damp blanket (or immediate Rug Proof cycle).
