What Are Laundry Detergent Sheets? A Complete Guide

Laundry detergent sheets are thin, flexible sheets of concentrated detergent. Each one holds a measured dose of cleaning ingredients in a film that dissolves when it hits water. You put one in the drum with your clothes, run the wash, and there is nothing to pour, measure or spill.

This guide covers what is in a sheet, whether they actually clean, how to use them, and how they compare with pods, liquid and powder.

What is in a laundry detergent sheet?

A sheet has two jobs: carry the detergent, then disappear. The carrier is usually a polyvinyl alcohol film, the same type of water-soluble film used for pods, designed to dissolve during the wash. The cleaning work is done by surfactants, the same kind of ingredients used in liquid detergent. They loosen soil and oils from fabric and hold them in the water so they rinse away.

Most sheets also include a few helpers: glycerin to keep the sheet flexible, a water softener such as sodium citrate so hard-water minerals don’t blunt the surfactants, and, in scented versions, fragrance. A good brand lists every intentionally added ingredient. You can see ours, with what each one does, on the Box of 50 page, and our label-reading guide explains how to read any detergent label.

Do laundry detergent sheets work?

Yes, for everyday laundry. A sheet contains the same kind of cleaning agents as liquid detergent, just without most of the water. When people are disappointed by sheets, it is usually for one of three reasons:

• One sheet on a big or very dirty load. Use two for a large or heavily soiled load.
• The sheet went in the dispenser drawer. Drawers are built for liquid and can hold a sheet back before it dissolves. Put it in the drum.
• Hard water. Minerals in hard water compete with any detergent. A sheet with a water softener in the formula handles it better.

Like any detergent, sheets do best when clothes have room to move. An overpacked drum is the most common cause of poor results with every format.

How to use laundry detergent sheets

1. Take a sheet out and close the box so the rest stay dry.
2. Put it straight into the drum, on top of the clothes. Not the dispenser drawer.
3. Run your usual cycle, hot or cold. The sheet dissolves during the fill.

Sheets work in HE, front-load, top-load and standard machines. They are low-sudsing, which is what HE machines need. Here is how much to use:

Tearing sheets in half for small loads is why a box of 50 sheets covers up to 100 loads. For a deeper look at dosing, see how much laundry detergent to use.

Do laundry sheets dissolve in cold water?

They are designed to. The film dissolves in cold water, and the agitation during the fill speeds it up. If you ever find a soft patch of film, the usual causes are a very short or very cold quick cycle with a packed drum, or a sheet that landed in the drawer. Put it in the drum first, add clothes, and give them room.

Laundry sheets vs pods

Sheets and pods are both pre-measured, so neither can be over-poured. The differences are practical:

Both formats should be kept in their packaging and out of reach of children.

Laundry sheets vs liquid and powder

Liquid detergent is mostly water, which is why a 90-oz jug weighs about 6 lb. A box of 50 sheets weighs about 3 oz. Liquid is handy for pre-treating stains, and you can keep a little for that while washing with sheets. The bigger issue with liquid is the cap: most people pour more than they need, which leaves residue in clothes and the machine.

Powder is cheap and stores well, but it can clump in humid places and leave white streaks on darks if it doesn’t dissolve fully, especially in cold water. Sheets avoid both problems.

What do laundry sheets cost per load?

Work it out from the number of sheets and how you use them. Our Box of 50 costs $19.95: that is about 40¢ for a full-sheet load, or about 20¢ a load if you halve sheets for small loads. Compare any brand the same way, using the sheet count rather than the load claim on the front.

Who are laundry sheets best for?

• Small spaces, where a jug takes up a shelf you want back.
• Shared or coin laundry, where you carry detergent with you.
• Travel, because sheets are dry and flat. See our travel laundry guide.
• Anyone who wants to stop measuring and spilling.

Frequently asked questions

Are laundry detergent sheets good?

For everyday laundry they clean as well as liquid when they are dosed right: one sheet for a regular load, two for a large or dirty one.

Can I put a laundry sheet in the dispenser?

No. Put it in the drum with your clothes. Drawers are built for liquid and can hold a sheet back.

Do laundry sheets work in HE machines?

Yes. They are low-sudsing and work in HE, front-load, top-load and standard machines.

Can I use laundry sheets for hand washing?

Yes. Dissolve half a sheet in a sink or basin of water, add your clothes, then rinse. Our hand-washing guide has the full steps.

How should I store laundry sheets?

Keep the box closed and somewhere dry. The sheets are designed to dissolve in water, so damp is the one thing to avoid.

Try them: the Toss & Go Box of 50 is up to 100 loads in a plastic-free cardboard box, in Fresh Meadow or Fragrance Free.
