Buyer Guide

Plastic vs stainless steel cloth clips: which should you buy?

Sinco Industries · February 2026

Both plastic and stainless steel cloth clips do the same job — hold washing on a line — but they fail in very different ways. Here is how to pick the right one for your climate, your fabrics and your budget.

What each clip is actually made of

A plastic cloth peg is injection-moulded from polypropylene (PP) with a small stainless steel torsion spring at the pivot. Good pegs use virgin PP rather than recycled regrind, because virgin polymer keeps its flexibility and colour far longer in sunlight. The metal you see is only the spring; the body is all plastic.

A stainless steel cloth clip is the opposite — the body and often the spring are both stainless steel, with no plastic to fade or crack. The trade-off is weight, price and a firmer, less forgiving jaw.

Grip strength and fabric safety

Plastic pegs have a slightly flexible jaw that conforms to fabric, which makes them gentler on delicate clothes — a textured PP jaw like our Misty hanging pegs grips without leaving marks. Steel clips clamp harder and flatter, which is exactly what you want for heavy, water-laden items like towels, jeans and blankets, but can crease lighter fabrics.

  • Delicates, shirts, kidswear: plastic pegs win.
  • Towels, denim, carpets, heavy wet loads: steel clips win.

Climate and durability

This is where the decision is usually made. In dry, sunny inland climates a quality virgin-PP peg lasts for years. UV is the enemy of cheap plastic — pegs made from regrind go brittle and snap after a season. In coastal and high-humidity climates, ordinary steel springs inside plastic pegs can rust and stain clothes; full stainless steel clips resist this and are the safer long-term choice near the sea.

Rule of thumb: inland and indoor drying → virgin-PP plastic pegs. Coastal, terrace or heavy-duty commercial laundry → stainless steel.

Cost and when each makes sense

Plastic pegs cost a fraction of steel and are what the overwhelming majority of households and laundries buy — they are cheap enough to replace and come in bright colours that sell on shelf. Steel clips cost more per piece but last far longer, so for a coastal household or a commercial laundry the lifetime cost can actually be lower.

For a retailer, the smart move is to stock both: a fast-moving plastic range such as Misha Gold and Sinco Super for everyday volume, plus a small facing of steel clips for the customers who ask for them.

The short verdict

There is no single "best" cloth clip — there is the right clip for the job. Plastic for everyday drying, value and colour; stainless steel for heavy fabrics, coastal humidity and long service life. As a manufacturer of both, we are happy to help retailers and buyers work out the right mix for their market.

Frequently asked questions

Are stainless steel cloth clips better than plastic?

Not universally — steel is better for heavy fabrics and coastal/humid climates, while quality virgin-PP plastic pegs are better for delicates, everyday drying, colour appeal and cost. The right choice depends on use.

Do plastic cloth pegs rust?

The plastic body cannot rust, but a cheap carbon-steel spring inside can. Quality pegs use stainless steel springs to avoid rust stains on clothes.

Which cloth clip is best for coastal areas?

Full stainless steel clips, because salt-laden humid air rusts ordinary springs. Where plastic is preferred, choose pegs with stainless steel springs.
