  8. How do you choose the right laundry detergent?

Choose laundry detergent by washer type, water temperature, fabric and cleaning needs. Liquid, powder and sheets each have trade-offs, while stain removers and laundry sanitizer address specific problems beyond routine washing.

Start with the care label on your clothes and the detergent directions. For an efficient washer, check that the detergent is marked for HE machines, and measure the amount for your load rather than pouring by habit.

This guide covers detergent formats, ingredients, special uses and stain treatment. Use the sections below to find the right topic, then follow the links to detailed comparisons and how-to advice.

How do you choose a laundry detergent?

Choose a detergent that fits your washer and the loads you wash most often. Then narrow it by scent, ingredients, temperature range and format.

A useful order is:

  1. Check the washer type. HE washers need detergent labeled for HE use.
  2. Consider water temperature. If you wash in cold water, confirm the detergent is made to work in it.
  3. Match the formula to your needs. Think about fragrance preferences, sensitive skin concerns, stains and odors.
  4. Pick a format you can dose correctly. Liquids, powders and sheets have different handling and storage needs.
  5. Read care labels and package directions. These give you fabric and dosing guidance for the load.

The right amount depends on the detergent directions and the load. Using more is not a reliable shortcut to a cleaner wash.

If you want to compare formats and use cases in more detail, our guide to what type of laundry detergent to choose can help you narrow the options.

What are the main types of laundry detergent?

The main types of laundry detergent are liquid, powder and sheets or other single-dose formats. Choose based on how you wash, what you need to treat and how easy each format is to store and measure.

FormatConsider it whenCheck before buying
LiquidYou want a pourable detergent or one that can be used to pretreat some stainsWasher compatibility, dose directions and storage
PowderYou prefer a scoopable format or want a bulk optionWhether it suits your usual water temperature and how you will keep it dry
SheetsYou want a compact, lightweight formatDose guidance, ingredient details and compatibility with your wash routine
Single-dose packsYou want a premeasured optionWhether the dose suits your load size and how to store packs safely

Format alone does not tell you how well a detergent suits your clothes. Compare the directions and features of the specific detergent, then choose the one that fits your routine.

For a closer look at dry detergent options, see our guide to bulk powder laundry detergent. If you are considering a compact format, read about laundry detergent sheets.

What type of detergent should you use in an HE washer?

Use detergent labeled for HE washers in a high-efficiency machine. HE detergent is designed for the lower water levels used by these washers, and the package gives the dose to use.

Check the washer manual and detergent label if you are unsure. Our explainer covers what HE laundry detergent is.

Is laundry soap the same as detergent?

Laundry soap and laundry detergent are different kinds of cleaning products. Their ingredients and intended use can vary, so check the label and washer guidance before switching between them.

See our comparison of laundry soap vs detergent for more on what separates the two.

Which detergent features matter for your laundry?

The most useful features depend on what goes into your hamper. Match the detergent to a real need, such as fragrance-free washing, cold-water cycles or hard water.

Should you choose fragrance-free detergent for sensitive skin?

If you want to avoid perfumes and dyes, choose a detergent that clearly says it is free of them. Product labels can help you compare ingredients, but individual preferences vary.

all free clear is unscented and 100% free of perfumes and dyes, and it is labeled for HE washers and cold water.

For more choices, see our laundry detergents for sensitive skin guide. If you are comparing another familiar brand, read our look at whether Xtra is a good laundry detergent.

Does detergent work in cold water?

Some detergents are labeled to work in cold water, but check the package instead of assuming every formula does. Cold-water directions can matter when you wash fabrics that call for cooler settings or want to use a cold cycle.

all free clear, Persil Intense Fresh and Tide Simply Free & Sensitive are described as working in cold water. For more on selecting a formula, see our guide to laundry detergent for cold water.

What should you know about hard water?

If you have hard water, compare detergents that are made for that condition and follow their dosing directions. Water conditions can affect washing, so a formula that suits your local water may be a practical choice.

See our guide to laundry detergent for hard water for options and buying points.

What are enzyme detergents?

Enzyme detergents use enzymes as part of their cleaning formula. The specific enzymes and claims vary by product, so read the ingredient and care directions for the detergent you are considering.

Our explainer covers what enzyme laundry detergent is. Enzyme formulas are one option to compare when you want help addressing certain kinds of soil and stains.

How should you handle stains and odors?

Treat stains based on the fabric and stain type, and use a stain remover only as directed. Detergent can clean a routine wash, but some stains call for pretreatment or a separate product.

Persil Intense Fresh can be rubbed onto a tough stain before washing, then left for 5 minutes according to its directions.

For other stain treatments, compare our guide to the best laundry stain remover. For white and colorfast items, learn how to use oxygen bleach in laundry.

Can laundry detergent stain clothes?

Laundry detergent can leave marks if it is used in the wrong amount or applied in a way the product directions do not recommend. Follow dosing guidance and washer instructions, and avoid leaving detergent on fabric longer than directed.

Our article explains whether laundry detergent can stain clothes and what to do if it happens. If detergent spills onto carpet, follow the steps in how to clean laundry detergent from carpet.

When do you need laundry sanitizer?

Laundry sanitizer is an optional additive for loads where sanitizing or odor control is a priority. It does not replace detergent, and you should follow the product directions for the cycle and dispenser.

Lysol Laundry Sanitizer Liquid is designed to be added to the fabric softener drawer or rinse cycle; it is also described for use as a presoak for certain virus-related claims.

Compare the differences in our guide to laundry sanitizer vs detergent. Use the exact directions on the sanitizer package for your washer and load.

Does fabric softener replace detergent?

Fabric softener does not replace detergent. Detergent cleans the load, while softener is a separate laundry product with a different purpose.

See fabric softener vs laundry detergent for a closer comparison. If you want a combined detergent and softener product, browse our guide to laundry detergents with fabric softener.

Scent beads are another separate add-on, not a detergent substitute. Our guide to non-toxic laundry scent beads explains what to check in their ingredients.

Which detergent choices fit common routines?

Choose a detergent by the feature that matters most in your laundry routine. Brand name, scent and bottle color alone do not tell you which formula is right for you.

Tide Simply Free & Sensitive is an unscented liquid with no dyes or perfumes, and it is described as suitable for standard and HE washers.

For brand comparisons, see Tide vs All laundry detergent and our guide to best laundry detergent for men. You can also compare best Arm and Hammer laundry detergents, best Purex laundry detergents and best Persil laundry detergents.

If scent is a priority, explore best scented laundry detergent or best luxury laundry detergents. For other brand questions, see whether All laundry detergent is good and learn what Tide Evo laundry detergent is.

Bottle color can help you recognize a product you have seen, but formulas and packaging can change. Use our guides to identify laundry detergent in a green bottle or [laundry detergent in a yellow bottle/].

For bulk purchases, check best powder laundry detergent in bulk.

What else belongs in a laundry care routine?

A detergent is only one part of laundry care. Use a separate tool or additive when it addresses a specific task, and follow its own directions.

Washer cleaner is intended for machine care rather than clothes washing. Compare washing machine cleaner tablets if you are looking for that kind of maintenance product.

Fabric softener and dryer sheets also serve different roles. See liquid fabric softener vs dryer sheets and our guide to eco-friendly fabric softener.

For clothes that need less wrinkling, a steamer may suit some garments. Read how to use a handheld garment steamer and compare a cashmere brush vs comb for knitwear care.

Frequently asked questions

What type of laundry detergent should I use?

Do laundry detergent sheets clean as well as liquid?

Detergent sheets are a compact format, but performance depends on the specific product, load and soil. Check the package for washer and water-temperature guidance, dose limits and ingredient information.
