Using the right amount of detergent — and knowing which additives are helpful versus harmful — can improve cleaning results and extend the life of your washing machine. At Jeffrey’s Appliance Service, we see many washer problems caused by too much detergent, the wrong type, or unnecessary additives.
How Much Detergent Should You Use?
Most people use far more detergent than needed. Modern high-efficiency (HE) washers require HE detergent, and even then, less is usually better.
Follow the measuring lines on the detergent cap or the instructions on the bottle.
For most loads, use about half of what you think you need, especially with concentrated formulas.
Soft water and smaller loads need even less detergent.
Too much detergent creates excess suds, leaves residue on clothes and inside the machine, and can lead to mold, odors, and drainage issues.
HE vs. Regular Detergent
Always use HE detergent in a high-efficiency washer. Regular detergent produces too many suds, which can cause the machine to shut down, leave residue, or damage components over time.
Common Laundry Additives — What’s Worth Using?
Helpful in moderation:
White vinegar — Can help with odors and residue when used occasionally (about ½ cup in the fabric softener dispenser). Don’t use it every load.
Baking soda — Useful for boosting cleaning power on very dirty loads or neutralizing odors.
Oxygen bleach (color-safe) — Generally safer than chlorine bleach for brightening and stain removal.
Use with caution or avoid:
Fabric softener — Coats fibers and can build up inside the washer, especially in the dispenser and on the tub. It also reduces the absorbency of towels. Many people skip it entirely.
Chlorine bleach — Effective for whites but harsh on fabrics, colors, and some washer components if overused.
Excess scent beads or pods — Can leave residue and aren’t necessary for cleaning performance.
Simple Habits for Better Results and a Healthier Washer
Measure detergent instead of pouring freely.
Run a monthly cleaning cycle with a washer cleaner or vinegar.
Leave the door open after loads so the tub can dry.
Clean the detergent dispenser regularly.
When Detergent Issues Cause Problems
If your washer smells musty, clothes come out with residue, or you’re getting error codes related to suds or drainage, excess detergent is often the culprit. In some cases, a technician needs to clean the internal filter in the machine more thoroughly or address related component issues.
