Fold lines that will not iron out of a stored suit

How to remove fold lines from clothes: tell a set-in crease that damp pressing can relax from a fold where colour or fibre has worn, and what to do about each.

Inspiration

Two different problems

A fold line that survives ordinary ironing is one of two things. Either it is a set-in crease, where the fibres have been bent the same way for so long that they hold the shape, and thorough damp pressing will usually relax it. Or the colour or the fibre itself has worn along the fold, which no iron can fix because the line is damage, not a crease.

Telling them apart takes a minute. Look at the line from the inside as well as the outside, and in daylight. A crease casts a shadow and you can feel a ridge. A worn fold looks paler or whiter than the cloth around it, even when you flatten it with your hand, and may feel thinner. A white line that vanishes when you dampen it and returns as it dries is usually detergent or starch residue, which a rinse removes.

Relaxing a set-in crease

Creases set hardest in cotton and linen stored for months under the weight of other clothes, and in anything that was starched before it was folded. Follow the care label for heat, and test on a hidden area first.

Dampen the line thoroughly, not just the surface. Spray it well, or lay a damp pressing cloth over it for a minute before you press.
Press at the fabric’s setting through the damp cloth, holding the iron still for a few seconds rather than gliding over the line.
Press from both sides. Turn the garment over and repeat on the reverse.
Use steam on stubborn lines, holding the iron or a steamer just above the fabric so the steam soaks in, then press again.
Let it cool flat before you move it. Fibres set in the shape they cool in.
Wash it if all else fails, where the label allows. A full wash and a press while still damp relaxes cotton better than spot treatment, and it removes old starch that holds creases in.

Synthetics and heat-set creases

Polyester and other synthetics are shaped by heat, which is how permanent pleats are made. A fold that was pressed in hot, or sat against a radiator or in a hot car, may be set for good. Steam it at the fabric’s low setting through a cloth and let it cool flat; it may soften the line without removing it. A dry cleaner’s professional press has more steam and suction than a home iron and is worth trying on a favourite piece.

When the colour has worn along the fold

Pale lines along folds on dark fabric come from rubbing, where the fold edge wears against the drawer or other clothes, from light fading the exposed edge of a folded piece, or from a print cracking where it was bent. The fibre is roughened or the dye is gone, so pressing will not bring the colour back. You still have options:

Wear it so the line hides, for example by folding a dupatta differently or placing the line under a belt or behind an arm.
Touch it in with a fabric pen made for the purpose, testing on an inside seam first, as the result can look patchy on a sheen.
Re-dye the whole piece if it is cotton or linen and the label allows; dyeing only the line will not match.
Restyle it so the line falls in a seam or is cut away. Our guide to restyling an old suit has ideas.

Stopping it happening again

Refold stored pieces in a different place every few months, roll dupattas rather than folding them, and pad sharp folds with acid-free tissue. Storing dupattas and embroidered suits and packing formal outfits for travel cover this in detail.

Unstitched suits often wait folded for a long time before they are made up. If yours has a fold line and you want it stitched with Stitching Only, send us photos of the line first; we confirm whether the fabric is suitable and whether the line can be placed out of sight before you send anything. Ask for a quote with those photos.

Common questions

Will a garment steamer remove fold lines?

It removes ordinary creases and softens many set-in folds, especially on lighter fabrics. Deep folds in cotton or linen usually need a damp press with an iron as well, as a steamer alone does not apply pressure.

Why does my black dupatta have white lines after storage?

Either detergent or starch residue has collected along the folds, which a rinse removes, or the dye has worn where the folds rubbed. Dampen a line: if it disappears and comes back as it dries, it is residue.

Can dry cleaning remove a permanent crease?

Professional pressing can often relax a crease that a home iron cannot, because it uses more steam and suction. It cannot restore colour or fibre that has worn away along a fold.
