Tide marks after drying on the line

Short answer: Tide marks are a ring of soil and detergent that collects where the fabric dries last. Rinse better, dose less and dry more evenly.

How a tide mark forms

As a wet garment dries, water migrates towards the areas that dry last. It carries dissolved soil and detergent with it and leaves a visible ring exactly there. That is why tide marks sit along seams, in collars and over the edge of a hanger.

Dosing and rinsing

Too much detergent means more residue to leave behind. Dose for your water hardness and load size. If your machine has an extra rinse, use it on thick items and on bedding where there is most fabric to rinse through.

Dry more evenly

Hang the garment so air reaches both sides, and avoid folding it double over a line. Turn it halfway through. Lay thick items flat on a rack instead of hanging them. See bamboo bedding.

How to remove a tide mark

Wash the item again on its own with no detergent and a cup of white vinegar in the softener drawer. If the ring is strong, soak it in lukewarm water first. See bamboo sheets and bamboo towels.

Frequently asked questions

Are tide marks a sign of poor water

Often yes. Hard water leaves limescale that makes the ring more visible.

Can tide marks be avoided in the dryer

Yes, because a dryer dries evenly. On the other hand the heat wears the fabric more.

Do tide marks fade on their own

No. They get clearer with every wash until you rinse them out.
