BioThane® Waterproof Collar & Lead Care

The easiest material to care for. BioThane is fully waterproof and wipe-clean — just don't neglect the hardware.

💧 Waterproof · Wipe clean
🧼
How to Clean
  • Wipe with warm water and mild soap
  • Use a soft cloth or sponge for stubborn mud
  • Rinse hardware with fresh water after sea or river swimming
💨
Drying
  • Towel dry after washing
  • Leave to air dry naturally
  • Avoid leaving near radiators or heaters
🚫
What to Avoid
  • Washing machines and tumble dryers
  • Bleach, vinegar or harsh solvents
  • Sand left inside D-rings or snap hooks
💡
Good to Know

BioThane itself doesn't absorb water or odour. The material is extremely hard-wearing. The hardware is the vulnerable part — always rinse and dry after saltwater or heavy mud exposure.

✓ Machine wash safe at 30°C gentle, in a laundry bag

Paracord Collar & Lead Care

Tough, quick-drying and resilient. Paracord benefits from gentle cleaning but is forgiving in daily use.

🪢 Tough · Quick-dry
🧼
How to Clean
  • Best: Hand wash in warm water with mild soap
  • Scrub lightly with a soft brush
  • Rinse thoroughly until water runs clear
  • Or: Machine wash in a laundry bag, 30°C gentle
💨
Drying
  • Pat dry with a towel first
  • Air dry flat or hanging
  • Keep hardware facing up so water drains away from joints
🚫
What to Avoid
  • Very hot water — can distort fibres permanently
  • Radiators or tumble dryers
  • Fabric softeners (affect grip on adjusters)
  • Sharp edges — paracord cannot be repaired once cut
💡
Good to Know

Saltwater is fine — as long as you rinse off afterwards. Always dry hardware completely to prevent dulling. Paracord is rated to 550lbs breaking strain, so the cord itself is rarely the part that wears out.

✓ Machine wash at 30°C gentle in a laundry bag — no fabric softener

PPM & Nylon Rope Lead Care

Lightweight, water-resistant and very low maintenance. The most common material for slip leads and custom rope leads.

🧵 Lightweight · Water-resistant
🧼
How to Clean
  • Hand wash with mild soap — best option
  • Rinse thoroughly until water runs clear
  • Machine wash is fine: laundry bag, 30°C gentle spin
💨
Drying
  • Towel dry to remove excess water
  • Air dry naturally — PPM dries very quickly
  • Nylon takes slightly longer — hang to speed it up
🚫
What to Avoid
  • High heat — can distort or melt rope fibres
  • Harsh bleach-based detergents
  • Leaving hardware wet in a bag after swimming
💡
Good to Know

PPM is naturally buoyant and absorbs very little water. Nylon absorbs slightly more but dries fast. Both materials are UV-stable and will hold colour well for years with basic care.

✓ Machine wash at 30°C gentle in a laundry bag

British Wool Collar Care

Naturally antimicrobial, breathable and beautifully textured. Wool needs slightly gentler handling than synthetic materials.

🐑 Sheep Shed Collection · Untreated wool
🧼
How to Clean

Brush it, do not wash it. The wool is untreated, which is what gives it the handle and the character. It also means it will felt if it gets wet and worked. Let mud dry completely, then brush it out with a soft brush and it will come up clean. Wool is naturally odour resistant, so it needs washing far less often than you would expect.

💨
Drying
  • Keep away from radiators and direct sunlight
🚫
What to Avoid
  • Washing of any kind — by hand or by machine
  • Getting it wet and then working it — that is what felts wool
  • Rough scrubbing or abrasive cloths
  • Tumble dryers
  • Wringing or twisting
💡
Good to Know

British wool is naturally odour-resistant, so you won't need to wash it as often as synthetic materials. Let it dry fully after heavy rain before storing. Wool stays warm even when damp.

✗ Do not wash · brush when dry

Cotton Rope Collar & Lead Care

Soft, natural and beautifully dyed — but more absorbent than synthetic rope. Allow plenty of drying time.

🌿 Cotton Mill Collection · Naturally dyed
🧼
How to Clean
  • Hand wash in cool or lukewarm water
  • Mild detergent only — no bleach or harsh chemicals
  • Spot clean individual marks where possible instead of full washing
  • Rinse thoroughly until water runs clear
💨
Drying
  • Gently towel dry to remove excess water
  • Hang or lay flat to air dry naturally
  • Allow full drying before storage to maintain shape
🚫
What to Avoid
  • Hot washes — cotton can shrink significantly
  • Machine washing
  • Long soaking — cotton absorbs a lot of water
  • Tumble drying
💡
Good to Know

Natural dyes can fade slightly over time — this is a characteristic of naturally dyed materials, not a defect. Always allow full drying before storing. Cotton is soft and comfortable but needs more care than synthetics.

Hand wash only in cool water — no machine wash

Premium Leather Care

Premium natural leather, vegetable-tanned and naturally finished. Ed sources the best hide available — Italian, French, British or bridle — chosen for quality above all else.

🟤 Ages beautifully · Condition regularly
🧼
How to Clean
  • Wipe with a damp cloth to remove dirt
  • A small amount of mild, unscented soap for stubborn marks
  • Remove mud and sand promptly — grit wears the surface over time
💨
Conditioning & Drying
  • If wet, towel dry then air dry naturally — never rush this
  • Condition every 2–3 months with a leather balm
  • Apply lightly and allow to fully absorb before use
  • Buff gently with a soft cloth
🚫
What to Avoid
  • Soaking in water — will damage the fibres
  • Saltwater — rinse leather and hardware immediately if exposed
  • Direct heat: radiators, fireplaces, tumble dryers
  • Heavy scrubbing or abrasive cleaners
💡
Good to Know

Leather will soften and develop a natural patina over time — this is not a defect, it's a sign of quality. Well-conditioned leather ages instead of wearing out. A patina collar tells a story. Embrace it.

✗ Never machine wash leather — wipe clean only

Hardware Care — Solid Brass, Plated Finishes & Zinc Die Cast

All hardware is load-tested by the suppliers I buy it from. It's built to last — but all metals need basic care, especially after water exposure.

🔧 Supplier load-tested · Twelve-month guarantee
🧼
General Care
  • Dry hardware immediately after any water exposure
  • Rinse with fresh water after sea, river or lake swimming
  • Don't leave wet collars folded inside bags
  • Inspect D-rings and snaps periodically for wear
  • Rinse especially where two different metals meet — that’s where salt does its work
Solid Brass

Develops a warm patina with use. If you prefer it bright, a soft cloth and brass polish takes it straight back to gold. Will not rust. Fitted throughout on the Sheep Shed, Cotton Mill, Greenwich editions and every leather piece.

🔩
Plated Finishes (Nickel & Gold)

A bright finish over a solid base — the snap hooks are nickel-plated solid brass, and the D-rings and rivets are brass, stainless steel, or steel with a black or gun-metal surface finish. On the customisable ranges, where you pick a plated finish, the buckle is plated over steel. The Sheep Shed, the Cotton Mill, the leather range and the Greenwich Yarn collars are the exception — every fitting on those is solid brass. At the points that rub, the plating thins first and the metal underneath begins to show. That’s wear, not a fault, and it doesn’t affect strength. Wipe dry after wet walks. Don’t use metal polish on a plated finish — like the die cast colours, it takes the plating off rather than bringing it back.

💡
Black & Gun-Metal (Zinc Die Cast)

Cast zinc is strong and holds its shape. The colour is a finish over the casting rather than the metal’s own colour, so unlike brass it can’t be polished back once it has worn — skip metal polish on these, it takes the finish off rather than restoring it. Rinse and dry after saltwater.

Send it back to me: If the hardware fails in the first twelve months I'll repair or replace it free. After that, send it back any time and I'll replace worn parts at cost plus postage. Read the full policy →

After the beach or a river swim —
one rule above all others

Saltwater and river mud don't damage BioThane, rope or paracord — but they will dull and corrode hardware if not rinsed off promptly. It matters most where two different metals sit against each other: zinc against brass or steel, sitting in salt, corrodes faster than either metal does on its own. A 30-second rinse under fresh water and a quick towel-dry after every wet walk extends the life of your piece significantly. It takes seconds and makes a genuine difference.

Hardware types at a glance

Brass
Solid Brass

Warm gold. Develops a patina with use, polishes back if you’d rather it bright, and will not rust. The most corrosion-resistant fitting I use. Standard throughout the Sheep Shed, Cotton Mill, Greenwich editions and leather, and available on every customisable piece. Load-tested by its manufacturer.

Nickel-Plated
Nickel-Plated

Bright silver. A nickel finish over a solid base: the snap hooks are nickel-plated solid brass, and the D-rings and rivets are brass, stainless steel, or steel with a black or gun-metal surface finish. On the customisable ranges, where you pick a plated finish, the buckle is plated over steel. The Sheep Shed, the Cotton Mill, the leather range and the Greenwich Yarn collars are the exception — every fitting on those is solid brass. Wipe dry after wet walks and the finish lasts years.

Zinc Die Cast
Zinc Die Cast (Black & Gun-Metal)

Deep matt black or dark grey. Cast zinc holds its shape and takes a knock well. The colour is a finish over the casting, so where it wears you’ll see lighter metal beneath and polish won’t bring it back. Rinse after saltwater.
