You grab your towel after a shot, wipe your club face, and the water just beads up or smears around. The towel feels wet, but it does not dry anything. This is frustrating, especially when you spent good money on an Under Armour product that used to work perfectly.
The good news is your towel is probably not ruined. Most cases of lost absorbency are reversible. The problem usually comes down to one of two things: a layer of residue blocking the fibers, or a damaged factory coating. This guide will help you figure out which one you are dealing with and what to do about it.
Common Reasons Under Armour Golf Towels Lose Absorbency
Microfiber golf towels work because the tiny fibers create a huge surface area that pulls water into the spaces between them. When something blocks those spaces or coats the fibers, water cannot get in.
Fabric Softener and Dryer Sheet Buildup
This is the number one cause. Fabric softeners and dryer sheets leave a waxy coating on fabrics. On cotton, this makes things feel soft.
On microfiber, it seals the fibers shut. Water hits the wax layer and rolls right off. If you have been washing your towel with fabric softener or tossing it in the dryer with a sheet, this is almost certainly your issue.
Sunscreen, Bug Spray, and Glove Oils
Golf exposes your towel to things most towels never see. Sunscreen and bug spray contain oils and chemicals that bond to microfiber. The oils from your golf glove and the sweat from your hands also build up over time. These contaminants are sticky. They grab onto the fibers and block water from getting through.
Detergent Residue from Overuse
Using too much detergent, especially liquid detergent, leaves residue behind. Microfiber is dense. It traps soap inside its fibers. Each wash adds a little more buildup until the towel becomes saturated with detergent rather than water. If your towel feels stiff or slightly greasy after drying, this is likely the culprit.
Heat Damage from Washing or Drying
High heat can melt microfiber fibers slightly. When the fibers melt, they lose their shape and their ability to create the surface tension needed to pull water in. This damage is permanent.
If you have been washing in hot water or drying on high heat, you may have damaged the fibers themselves. A good test is to feel the fabric. If it feels crispy or stiff rather than soft and plush, heat damage is likely.
Degraded Factory Hydrophilic Coating
Under Armour applies a special finish to many of its towels to make them absorb water instantly. This finish is called a hydrophilic coating. Over time, with repeated washing and harsh chemicals, this coating wears off.
Once it is gone, the towel acts like untreated microfiber. It may still absorb, but much slower. This is different from residue buildup because the towel feels clean and normal; it just does not work as well.
How to Diagnose the Real Problem with Your Towel
Before you start cleaning the towel, take a minute to figure out what you are dealing with. This saves time and prevents you from damaging a good towel with the wrong treatment.
The Water Drop Test
Take a dry section of your towel and drop a single drop of water onto it. Watch what happens.
If the drop soaks in within two seconds, your towel is fine. The problem is likely just saturation. You are using a wet towel to try to dry a wet club.
If the drop sits on top of the fabric for 5 seconds or more before slowly soaking in, you have residue buildup or a degraded coating.
If the drop beads up and rolls off completely, you have a heavy layer of residue or a completely stripped coating.
The Touch Test for Residue
Rub a clean, dry section of the towel between your fingers. Does it feel soft and fluffy? Or does it feel slightly greasy, waxy, or stiff? Greasy or stiff indicates residue. Soft and fluffy but non-absorbent points toward a worn coating.
The Smell Test
Smell the towel after it is completely dry. A musty, sour, or chemical smell means you have detergent or oil buildup. A neutral smell means the towel is probably clean, but the coating has worn away.
How to Restore Absorbency to Your Under Armour Golf Towel
The right fix depends on what is wrong. Start with the simplest method and only move to stronger treatments if needed.
Method 1: Strip the Residue with Vinegar
White vinegar dissolves detergent residue and softener buildup without damaging microfiber. This is your safest first step.
Fill your washing machine with warm water. Not hot. Warm.
Add one cup of white vinegar to the detergent dispenser or directly to the water. Do not add any detergent.
Put your towel in and run a full cycle.
After the cycle finishes, smell the towel. If it still smells like vinegar, run another rinse cycle with just water. The vinegar smell will disappear once the towel is dry.
Dry the towel on low heat or air dry. Do not use a dryer sheet.
This method works for most residue problems. It removes the wax and soap layers that block water.
Method 2: Deep Clean with Baking Soda
If vinegar alone does not work, follow it with a baking soda wash. Baking soda breaks down oils from sunscreen and glove grease.
Start with a warm water cycle.
Add half a cup of baking soda directly to the drum with the towel.
Do not add detergent or vinegar at the same time.
Run the cycle.
After that, run a second cycle with just water and half a cup of vinegar to neutralize any remaining baking soda.
Dry on low heat.
Method 3: The Dishwasher Degreasing Method
For heavy oil buildup that baking soda cannot touch, use a dishwasher. This sounds odd, but dishwashers use high-pressure hot water and detergent designed to break down grease.
Place the towel in the top rack of your dishwasher.
Do not use regular dishwashing detergent. Use a small amount of a grease-cutting dish soap, like Dawn.
Run a normal cycle with heated dry turned off.
After the cycle, rinse the towel by hand to remove any soap residue.
Dry on low heat.
This method is aggressive. Only use it if you know your towel has heavy sunscreen or oil buildup and gentler methods have failed.
Method 4: Rewetting the Coating
If the water drop test showed slow absorption but no residue, your coating may be depleted. You cannot restore the factory coating at home, but you can improve absorbency with a commercial microfiber reviver treatment.
Look for a product labeled as a microfiber wash or microfiber detergent booster. These contain chemicals that help the fibers attract water again.
Follow the instructions on the product. Most require soaking the towel in a solution for several hours before washing.
What to Do If Nothing Works
Sometimes a towel is simply done. If you have tried vinegar, baking soda, and a rewetting treatment and the towel still repels water, the fibers may be heat-damaged, or the coating may be completely gone.
At this point, your best option is to replace it. A towel that does not absorb is just a rag. It will not help you on the course.
How to Wash Your Under Armour Golf Towel So It Stays Absorbent
Prevention is easier than restoration. Follow these rules to keep your towel working.
Use the Right Detergent
Use a detergent that is free of fragrances, dyes, and fabric softeners. A free and clear liquid detergent works well. Better yet, use a detergent made specifically for microfiber. These are designed to clean without leaving residue.
Never Use Fabric Softener
This is non-negotiable. Fabric softener ruins microfiber. If you use a laundry pod or liquid that contains softener, switch to a version without it.
Skip the Dryer Sheets
Same rule applies. Dryer sheets leave a waxy film that blocks absorbency. If you want your towel to feel soft, dry it on low heat with no additives.
Wash in Warm Water, Not Hot
Hot water can damage the fibers and strip the coating. Warm water is hot enough to clean but safe for the fabric.
Air Dry or Use Low Heat
High heat is the fastest way to ruin a microfiber towel. Air drying is best. If you use a dryer, use the lowest heat setting and remove the towel while it is still slightly damp.
Wash Separately from Cotton Items
Cotton lint transfers to microfiber during washing. That lint blocks the fibers. Wash your microfiber towels alone or with other microfiber items.
Rinse After Every Round
Do not let sunscreen, sweat, and grass dry into the fibers. Rinse your towel with clean water after each use and hang it to dry. This simple habit prevents most buildup problems.
Frequently Asked Questions
Can I use dryer sheets on my Under Armour towel?
No. Dryer sheets leave a waxy coating on microfiber fibers that blocks water absorption. Use them on your cotton clothes, not your golf towel.
What temperature water should I use to wash a microfiber golf towel?
Use warm water. Hot water can damage the fibers and remove the factory coating. Cold water may not dissolve detergent and oils effectively.
Why does my towel feel slimy or waxy after washing?
This means you have detergent or fabric softener buildup. The slime is residue trapped inside the fibers. Wash the towel with vinegar to strip the buildup.
How often should I replace my golf towel?
With proper care, a quality microfiber towel lasts one to two seasons. Replace it when it no longer absorbs water after a deep clean, or when the fabric feels stiff and rough.
Will bleach ruin my Under Armour towel permanently?
Yes. Bleach breaks down microfiber fibers and destroys the absorbent coating. Never use bleach on a microfiber towel.
Can I wash my golf towel with my regular gym clothes?
You can, but it is not ideal. Your gym clothes may have fabric softener residue or lint that transfers to the towel. Wash microfiber items separately for best results.
