The right amount of detergent is usually what the label recommends for your load size and soil level — more soap does not always mean cleaner clothes, and too much can leave residue. High-efficiency (HE) machines need low-sudsing detergent. Pods, powder, and liquid all work when you put them in the right place and give them enough water and time to dissolve.
Fabric softener is not detergent. Downy and similar products go in the softener dispenser or a later rinse, not in place of soap. Some people add vinegar or baking soda to a load; some combinations are routine, and some — especially anything mixed with chlorine bleach — are not safe.
The guides below cover dose, HE and regular washers, pods and powder, substitutes, mixing, storage, and safety questions. They do not replace the directions on the bottle or box you actually own.

Frequently asked questions
How much laundry detergent should I use?
Use the amount on the label for your load size and how soiled the clothes are. A little less is often enough in soft water or with a small load; more is not automatically better and can leave residue. Our dosing guide walks through ounces per load in more detail.
Can I use HE detergent in a regular washer?
Yes. High-efficiency detergent is low-sudsing, and it can be used in a regular (non-HE) machine. A regular, higher-sudsing detergent is the one to avoid in an HE washer. Check the bottle for the HE symbol.
Is Downy a laundry detergent?
No. Downy is a fabric softener, not a detergent. It does not replace soap. Use it in the softener dispenser or a later rinse, and wash with a detergent as you normally would.
Can I mix vinegar or bleach with detergent?
Detergent and chlorine bleach are often used in the same wash when the label allows bleach, but they should not be poured together as a concentrate. Never mix vinegar with chlorine bleach; that combination can release chlorine gas. Separate guides below cover vinegar, bleach, and other additives.
