Most people wash their towels regularly but still end up with ones that feel scratchy, smell a bit off, or lose their absorbency after just a few months. The frustrating truth? Washing towels incorrectly can damage them faster than almost any other factor.
The good news is that the right technique is simple. Follow these guidelines and your cotton bath towels will stay soft, fresh, and genuinely effective for years, not months. For guidance on when it's time to replace them entirely, see our article on how to tell if your cotton towels need replacing.
And if you're unsure how often to even bother washing them, this article has you covered too.
How Often Should You Wash Your Cotton Bath Towels?
This is one of the most common questions, and the answer is more frequent than most people realise.
Dermatologists and health organisations recommend washing bath towels every 2 to 3 uses. That might sound excessive, but consider what a towel actually collects: dead skin cells, body oils, residual moisture, and microbes from the bathroom environment.
“Even "clean" towels can harbour particles of E. coli and MRSA if they do not dry completely between uses.” — Cleveland Clinic
If you're recovering from a skin infection, have a condition like eczema, or share towels with others, wash after every single use.
The Right Detergent Makes a Real Difference
Most people don't think twice about their detergent, but for cotton towels, it matters. Here's what to look for:
• Use liquid detergent, not powder. Powder detergents don't always dissolve fully in a washing machine drum, and residue left in the terry loops is a major cause of stiffness and skin irritation.
• Choose fragrance-free and dye-free formulas. These are gentler on the cotton fibres and won't trigger reactions in people with sensitive skin.
• Use the recommended amount (or less). More detergent doesn't mean cleaner towels. It just means more residue.
Never Use Fabric Softener on Cotton Towels
This is the single most common towel-care mistake, and it's a significant one. Fabric softeners and dryer sheets work by coating fabric fibres in a waxy, hydrophobic (water-repelling) film. On cotton towels, this:
• Reduces absorbency (the very thing you need from a towel)
• Traps chemical fragrances in the fabric
• Causes the loops to mat together and feel stiff over time
If you want to maintain that soft, fluffy texture, use wool dryer balls instead. They physically separate and agitate the fibres during drying, which maintains plushness without any chemical coating.
Water Temperature and Wash Settings
Cotton towels are durable enough for warm to hot washing cycles, and for hygiene, warmer temperatures are better. A 60°C wash is effective at killing most bacteria and mould spores that accumulate in damp fabric.
However, very high temperatures over extended periods can weaken cotton fibres and cause colour fading. For most regular washes, a 40–60°C cycle is the ideal balance of hygiene and care.
One setting that's absolutely worth using: the extra rinse cycle. Towels trap detergent residue in their loops more than almost any other fabric. An extra rinse ensures that residue is properly flushed out, which keeps the cotton fibres clean and the surface free from irritants.
Drying Your Cotton Towels Properly
How you dry your towels affects their lifespan just as much as washing them:
• Tumble dryer: Effective, but don't overheat. High heat over time degrades the hollow lumen structure of cotton fibres, reducing absorbency. Use a medium heat setting.
• Line drying: Great for the environment and gentle on fibres, but can leave towels feeling stiff. Give them a brief tumble at low heat or a good shake before hanging to maintain softness.
• Never leave damp towels bunched up or in a pile. This is a fast track to mildew and that persistent musty smell that doesn't wash out easily.
Restoring Towels That Have Gone Stiff or Stopped Absorbing
If your towels are already stiff or have lost their absorbency, try this two-step fix before replacing them:
• Step 1: Wash with 240ml of white vinegar (no detergent). Vinegar breaks down detergent residue and dissolved mineral deposits.
• Step 2: Run a second cycle with 120g of bicarbonate of soda. This deodorises and helps loosen any remaining buildup.
Follow up with a low to medium heat tumble dry with wool dryer balls. Many towels recover significantly after this treatment.
Summary: The Quick-Reference Rules
• Wash every 2–3 uses (after every use if you have a skin condition)
• Use liquid, fragrance-free detergent, and not too much
• Never use fabric softener or dryer sheets
• Run an extra rinse cycle
• Dry thoroughly before folding or hanging
• Add wool dryer balls to the tumble dryer for natural softness
