How to care for shibari rope

Rope care is mostly inspection. The oiling and maintenance matter less than the habit of looking at a rope before you tie with it.

Jute wants a check before every tie, oil every couple of months, and a decision at some point about when it stops being a suspension line. POSH wants a wash now and then and the same inspection.

One rule sits under all of it: every step you take to make rope softer or cleaner spends some of its working life. That is a reason to do less, not more.

The short version

	Ogawa jute	POSH
Before every tie	Run the full length through your hands	Same
Before suspension	Full inspection, unhurried, good light	Same
After each tie	Inspect, dry, hang	Inspect, dry, hang
Monthly	Cloth pull along the length	Visual check
Every couple of months	Oil if it feels dry	Nothing
Wet rope	Out of load-bearing use until dry through	Hang dry, never tumble
Comes out of suspension-line use	Late-life hairiness, thinning, high stranding, brittleness	Permanent flattened kinks
Off the body entirely	Broken strand, mould, heavy kinks, unknown history	Same

Inspection, which is the actual work

Before every tie, run the full length through your hands. You are feeling for anything that changed since last time: set from storage, damp, a lump, a hard spot.

Before anything load-bearing, do it properly. Unhurried, in good light, along the whole working length.

Wear is not evenly distributed, so look hardest where it concentrates:

• The bight. The fold takes the most work of any part of the rope.
• The last metre at each end, and any whipping or knot that holds the lay together.
• Anywhere that met hardware, a ring, a carabiner, a bamboo.
• Sections that carried frictions or sat under concentrated load.

Stop on any of: a cut or broken strand, broken yarns, permanent flattening, lumps, glazed spots, mould, a chemical smell, or discolouration you cannot explain.

Inspect again after anything unusual: a snag, a shock load, getting wet, or a stretch where someone else had the rope.

After each tie

1. Untie and shake out. Loose dust, body oils, lint. Let the rope drop to length.
2. Inspect, as above.
3. Dry. If the rope is at all damp, hang it. Never put damp rope away.
4. Hang. Folded in half over a bar, hook, or rack, in a room with airflow, out of direct sun.

Jute, month by month

Our jute is cleaned and hand-finished in Leuven, and ships ready to tie with. You do not need to do anything to it on day one.

Over months of use it dries out, fuzzes up, and wants maintenance.

Monthly. Pull the rope through a folded soft cloth, an old cotton T-shirt works, to clean off lint and surface dust. While you are doing it, feel the whole length for stiffness, thinning, or a strand sitting proud.

Every couple of months, or when it feels dry. Oil rubbed between your palms, then pulled along the length. Not a coating. The rope should feel slightly less dry, not visibly wet. Hang it a day afterwards so the excess works in.

Which oil. Most oils work. A few actively do not.

Jojoba, camellia (tsubaki), and soybean all do the job. Some people’s conditioning guidance uses jojoba, camellia is a traditional choice, and soybean is what others have used. At the end of the day any stable oil is a valid choice. Pick one and stay with it rather than layering products.

Avoid kitchen oils that go rancid: olive, sesame, sunflower. Some people finish rope with a thin coat of beeswax, and that can work; we avoid heavy waxes that build up, and anything scented. The point is supple fibre, not perfumed rope.

Singeing. Singeing burns surface fuzz off and brings back some of the smooth look. Plenty of people enjoy doing it, though every pass makes the rope slightly weaker.

Inspect before you singe, not after. Fine fuzz on new or newly finished jute is cosmetic. Hairiness that shows up after months of use may be broken fibre, and that is a signal about the rope’s condition. Burning it off destroys the evidence rather than the problem. If you cannot tell the two apart, do not singe it.

The technique is easier to learn standing next to someone than from a paragraph. Ask in a class, or message us.

Boiling. You can boil jute. We would not. Heat weakens the fibre, water weakens the lay, and boiling is the hottest thing most people will do to a rope. The less you do to jute, the longer it lasts. Raw jute off a spool is a different situation, covered in breaking in new jute.

Cleaning jute

Jute does not go in the washing machine. Water and agitation loosen the twist that holds the rope together, and heat makes it worse. Cleaning is spot work.

• Spot clean. A cloth damp with water, worked on the mark only. Hang the rope until dry all the way through before it goes away.
• Air it. Smell is usually retained moisture rather than dirt. Several days hanging somewhere with airflow fixes more than washing would.
• Know the limits. A mark that will not lift is cosmetic and does not affect strength. A smell that survives several days of airing is moisture or growth in the fibre, and that is a retirement signal rather than a cleaning problem.

Jute cannot be disinfected. Rope that has taken blood or other body fluids does not go back into shared use, whatever it looks like afterwards. Nothing on this page removes solvents, bleach, or oil-based contamination either. None of them belong on rope, and rope that has met them is ready to be retired.

Drying, and never tying on damp rope

Wet jute is weaker than dry jute. A rope that has taken water comes out of load-bearing use until it is dry all the way through, and that takes longer than it feels. An 8 m rope soaked through needs a day or two hanging in moving air, not the couple of hours the surface suggests.

Air, not heat. A radiator, a hairdryer, or a tumble dryer will get the water out faster and take fibre life with it. Heat weakens jute every time, and the less you do to a rope the longer it works.

In an apartment with no drying room, a clothes airer near an open window works, or a hook on the back of a door left ajar. A dehumidifier in the same room speeds things up without heating the rope. The airing cupboard does not, because it is warm and the air is still.

Storage

Both fibres want the same conditions: cool, dry, ventilated, not crammed.

• Hanging is best. Folded over a rack or hook somewhere that breathes.
• Loose coils are fine. Coil the rope loosely and secure it with a loose tie, in a bag that closes but is not airtight.
• Avoid tight bundles for months, damp cupboards, direct sun, and sealed plastic bags.

Canvas or a rope roll beats a plastic bag for travel. Both fibres pick up humidity in poor storage and need a longer hang afterwards.

Coming back after a long pause. POSH picked up after six months is generally ready. Jute may not be. Expect stiffness and expect the rope to have set into its stored shape. Marks from storage are usually compression rather than creasing, so treat a rope out of long storage as a rope to inspect, not a rope to tie with immediately. Run it through your hands, oil it if dry, hang it a day, and inspect it properly before it carries anything.

Knotted and whipped ends

Shibari rope ends are usually secured with whipping or a knot. We use a single overhand knot. If either finish fails, the rope will start to unlay.

Check the finish every time you inspect the rope. Replace loose or damaged whipping, or re-tie a knot that has worked loose, before the next use.

If the fraying has gone past the knot or whipping and into the lay, cut back to sound rope and re-finish the end. You lose a few centimetres, the alternative is losing the rope.

When a rope stops being a suspension rope

Retirement is not one decision.

Rope loses strength you cannot see over time. Age and use count even when damage does not.

Out of suspension-line use. Anatomie, who sell rope and write about it well, publish four signals under a heading that promises five. The four are the ones worth having.

• Late-life hairiness. Loose surface fluff is normal and increases with age. What matters is fibre that parts when you put tension on it. Pull a suspect section firm between both hands: fluff lies down, damage separates.
• Thinning. Compare the rope against itself. Measure a hard-worked section, the bight especially, against the last half-metre at an end, which sees far less load. The caliper method is in rope thickness. A worked section that is measurably thinner than an unworked one has lost material.
• High stranding. One strand riding higher than the other two means the load is no longer shared evenly between the three.
• Brittleness. Rope that feels like straw, crunchy and dry, after conditioning and a few uses.

Jute rope is usually three strands of twisted fibre. Broken fibres mean fewer intact fibres carrying the load in that section, whatever the strand count looks like from outside.

Off the body entirely. A cut or broken strand, fused or glazed patches, mould or mildew, or damage you cannot confidently classify. Do not keep testing damaged rope on a person to see whether it holds.

Mark a rope when you demote it, and keep it somewhere else. Dip dyeing the end, a line with a permanent marker, a second colour of whipping thread at both ends, or keep in a different bag. A mark you cannot see across the room will not survive the next time you pack in a hurry. The same goes for fully retired rope: cut it short so nobody can pick it up and tie with it by mistake.

If you are unsure a rope will hold the load, do not use it. We finish and inspect rope. We do not certify any rope for suspension, and the judgement on the day is yours, at your own risk.

POSH, almost nothing

POSH does not need oiling, singeing, or conditioning. There is no finish on it to dry out or replace.

Washing. Rope inside a bag or pillowcase, tied shut. Cool water, delicate cycle, low spin, a clear dye-free detergent. No fabric softener and no dryer sheets: both leave a lubricant on the surface, and a slicker rope holds a friction less well.

Hang it to dry. Never tumble dry, even on low. deGiotto, who also sell POSH, put it plainly: never put POSH in a clothes dryer. Tumbling sets twist into the lay and abrades the surface.

POSH does not need washing monthly. We wash ours when it visibly needs it, which for most people is once or twice a year.

Heat and friction. Keep POSH away from radiators and other heat sources, and keep it slow over hard surfaces: a fast pull against a metal carabiner builds enough heat to glaze it. Do not iron or steam it.

POSH retirement. Stop using it on a body if you find a cut strand, fused or glazed fibre, an unexplained lump or thin section, or a flattened kink that does not come out with gentle flexing. A kink that disappears under slight tension is fine. One that has set is not. When you are uncertain, retire it rather than testing it with a person.

Hemp, briefly

Hemp follows the same cadence as jute: inspect, oil when dry, store hung. It is not batched with mineral oil, so the smell question that comes with jute does not arise. Some people finish hemp with wax rather than oil. We do not stock hemp, and the comparison is in jute vs hemp.

What we actually do

Ogawa jute and POSH, both Belgian-finished and hand-packed in Leuven, usually dispatched within two working days. Every length of rope is inspected before it goes on sale.

If you want rope you can wash without thinking about it, buy synthetic rather than natural. That is a real argument for POSH, and deGiotto sell it too if you would rather buy elsewhere.

The starter kit arrives ready to tie. The fibre comparison is in POSH vs jute, the batching chemistry is in JBO and batching oils, and cutting rope off in a hurry is in safety cutters.
