How a good lodge keeps its linens white and soft for a decade, and why your towels stopped absorbing.
This is the part of the subject nobody owns. Search any towel-care question and you will find laundry services, detergent brands and towel manufacturers -- every one of them with something to sell you that is not the answer. The honest answer is usually cheaper than a purchase and takes one wash cycle.
Towels do not wear out. They stop working. They go stiff, or stop absorbing, or start smelling within an hour of coming out of the dryer. Every one of those is a build-up problem -- of fabric softener, of detergent residue, of hard-water minerals, of body oil -- and every one is reversible.
Start with the hotel laundry method if you want the whole system, or go straight to the symptom: not absorbing, smelling, stiff, or gray.

Hotel and lodge laundries are not gentler than home laundries. They are considerably harsher: hotter water, stronger alkali, oxygen bleach in almost every load. Their linens last for years anyway, because harshness is not what damages cotton -- chlorine bleach, fabric softener and high dryer heat are.
The three things a commercial laundry does that a home laundry usually does not: it washes hot enough to melt body oil rather than smear it; it uses an alkaline builder to keep minerals in solution so they rinse away; and it never, under any circumstances, uses fabric softener on towels.
Fabric softener works by depositing a thin layer of cationic surfactant -- functionally, a fine waxy film -- on the fiber. That film is what makes laundry feel soft, and it is water-repellent. On a shirt this is harmless. On a towel it is the exact opposite of the product's purpose.
The damage is cumulative and invisible until the towel simply stops working. It is also completely reversible: stripping the towels removes the build-up, and most people are astonished by how much comes out of towels they thought were clean.
Chlorine bleach whitens by attacking what is on the fiber and then the fiber itself. It weakens cotton with every use, which is why heavily bleached white towels go thin and tear at the hem while still looking fine. Oxygen bleach -- sodium percarbonate, the active in most color-safe whiteners -- lifts the soil and leaves the cellulose alone, and can be used in every single wash without cost.
The one requirement is temperature: percarbonate needs warm water to release its oxygen. In a cold wash it does approximately nothing. Oxygen versus chlorine bleach has the full comparison, and keeping white towels white is the practical routine.
Almost always fabric softener or detergent residue coating the fibers, sometimes hard-water minerals. It is reversible -- see towels not absorbent and how to strip towels.
No. Softener deposits a water-repellent film on the fiber, which is exactly the opposite of what a towel is for. The damage builds up invisibly over months.
Oxygen bleach in a warm wash, repeated over several cycles. Chlorine bleach whitens faster and weakens the cotton every time. Full routine here.
Warm to hot -- around 104-140F (40-60C). Cold water does not melt body oil or activate oxygen bleach, which is why cold-washed towels tend to smell.
