The short answer
The best detergent for towels is a low-suds, no-residue formula that rinses out completely, because residue buildup is the main reason towels smell musty when wet. Clean Guy's 6-enzyme system breaks down trapped body oils while rinsing clean, keeping terry absorbent and genuinely fresh.
Updated June 2026
Why towels go musty
Towels are dense, absorbent, and used damp by design, which makes them the easiest fabric in the house to wash wrong. The usual culprits are detergent residue from overloaded machines, body oils that survive weak formulas, and slow drying that lets mildew set in. The Clean Guy formula attacks the first two directly: a low-suds, no-residue clean that rinses out completely instead of coating the loops.
The towel routine
Wash towels on their own in warm water with room to move. Skip traditional liquid softener, which coats terry loops and reduces absorbency over time. Dry completely every cycle, and hang towels to air out between uses. Note that dryer sheets are best kept off microfiber towels specifically, where they can reduce absorbency and wicking.
The absorbency economics
A towel's entire job is absorbency, and almost everything the laundry aisle sells works against it. Liquid softeners coat terry loops with wax. Overloaded machines leave detergent in the pile. Heavy fragrance masks the problem while the buildup compounds. Within months, a quality towel performs like a cheap one. Reversing it is mechanical: a no-residue wash strips the buildup over a few cycles, full drying stops the mildew cycle, and the towel you bought comes back. The detergent choice is not about scent here. It is about what gets left behind, which should be nothing.
Mistakes that keep towels musty
The towel cycle of doom has three stages, and most households run all of them. Softener for the fluffy feel, which coats the loops and starts the absorbency decline. Overloading, because towels are just towels, which locks residue into the pile. And the hamper hold, where a damp towel waits two days for wash day, growing the mildew the wash then has to fight. Break all three at once: no liquid softener, towels as their own honest-sized load, and damp towels hung spread until laundry day. The no-residue formula handles the rest, and within three cycles the wet-towel test stops being a gamble.
The towel reset
- Strip the buildupTwo or three cycles with a full dose of no-residue detergent and no softener.
- Dry completely, every timeEven slightly damp towels feed mildew. Full cycles, no shortcuts.
- Hang with airflowSpread between uses. A bunched towel never dries and never stays fresh.

Good to know
Why do my towels smell musty after washing?
Residue buildup and incomplete drying are the usual causes. Wash towels alone without overloading, use a no-residue detergent, and dry them fully every cycle.
What is the best detergent for towels?
A full-strength formula that rinses clean. The Clean Guy low-suds, no-residue enzyme system is built to clean dense terry without coating it.
Should I use fabric softener on towels?
Avoid traditional liquid softeners, which coat towel fibers and reduce absorbency. Skip dryer sheets on microfiber towels specifically for the same reason.
How often should towels be washed?
Bath towels are best washed after three or four uses, sooner in humid climates, and always hung to dry fully between uses.
How do I strip towels without special products?
Run them through two or three normal cycles with a full dose of a no-residue enzyme detergent and nothing else. The buildup releases progressively without dedicated stripping agents.
Why do new towels stop absorbing after a few months?
Softener coating and detergent residue accumulate in the loops. Cut the softener, avoid overloading, and the absorbency returns over a handful of washes.
Do gym towels need different care than bath towels?
Wash them more often and hotter on the schedule, not the formula. Gym towels collect concentrated sweat oils, so they earn a wash after every session or two, while the same no-residue, full-dry routine applies across both.
