How To Wash Car Microfiber Towels

If it is machine washing, the first thing is to completely separate the towel that has wiped the heavy stain area of the wheel hub from the towel that has wiped the paint surface. Then, choose a professional microfiber cleaning agent, or liquid laundry detergent without additives, set to warm water washing.

The most important point: Never use fabric softener, bleach or washing powder. After washing, either dry at low temperature or dry directly with cold air. Never use those drying paper (dryer sheets).

For hand washing, rub gently in a bucket with warm water and a suitable detergent, then rinse repeatedly in another bucket until the water is completely clear. Finally, gently squeeze the water (don’t twist too hard) and put it in a well-ventilated place to dry naturally.

Machine Washing Method

If you want to wash your towels like new, but don’t want to damage the fiber structure, it is very important to follow these machine washing steps.

Step 1: Preparation Before Washing

The most critical step before throwing towels in the washing machine is sorting. This is also a lot of novice easy to ignore the place. You must separate the towels that wipe the heavy oil areas of the wheel hub and engine compartment from the towels that wipe the paint, glass and interior.

Why? It’s to prevent cross-contamination. The wheel hub is often covered with brake dust and heavy oil sludge. If these hard particles are transferred to the towel for cleaning the car paint, the next time you wash the car, you will be grinding your car paint with sandpaper.

In order to achieve the best results, I personally suggest that you can divide it into more details: separate the collected towels, waxed/polished towels and ordinary cleaning towels.

Step 2: Choose The Right Detergent

Be sure to use a cleaner specifically designed for microfiber, or a mild liquid laundry detergent that does not contain flavors or dyes. Here are 3 things that are absolutely forbidden to use. I have seen too many towels scrapped due to misuse of these things in the store:

Fabric Softeners: This is the killer of microfiber. It will leave a layer of coating on the surface of the fiber, directly blocking the micropores, resulting in a serious decline in the water absorption and cleaning ability of the towel.
Bleach: This chemical will destroy the fine structure of microfiber, so that the life of the towel is greatly reduced.
Powdered Detergents: try not to use powder. In warm or cold water washing, washing powder often does not dissolve completely, and those small particles that do not dissolve will get stuck in the fiber. The result is that the towel hardens and even scratches the paint while wiping the car.

Step 3: Set The Appropriate Program

Set the washing machine to warm water (approximately 40°C / 104 °F) and soft mode. In my experience, warm water is enough to break down dirt and residual car wax, but if the water is too hot, it can cause polyester and polyamide fibers to shrink or even damage.

If your towel is particularly dirty, I recommend soaking it in warm water and detergent for 15 to 30 minutes, which will effectively soften those stubborn stains.

Step 4: The Drying

The wrong drying method can ruin your towel.

Dryer setting: If you must use the dryer, be sure to select the “low temperature” or “no heat (air dry)” gear. High temperature will melt or damage those fine fibers, so that the towel loses softness, and the ability to catch dirt will disappear. Also, don’t use drying paper. Like softener, the residue it leaves behind will directly waste the performance of the towel.
Natural air drying: Just hang the towel in a well-ventilated place. The characteristics of microfiber itself determine that it dries very fast.

Hand Washing Method

If you only have a few towels in your hand, or if they are only slightly dirty, hand washing is a very efficient alternative.

Step 1: Preparation

Prepare two barrels. This is the same logic as the “two buckets of water method” when we wash the car. One bucket is filled with warm water and an appropriate amount of microfiber special cleaning agent (or mild laundry detergent), and the other bucket is filled with clean warm water for rinsing.

Step 2: Washing And Rinsing

Soak the towel in a bucket of detergent and gently rub and squeeze it with your hands. This step is to allow the detergent to penetrate into the fibers and break down the dirt. After washing, put the towel in a bucket of clean water. Be more patient here, rinse and squeeze repeatedly until the water is completely clear and you can’t see any foam or dirt. Thorough rinsing is very important, even if a little residual detergent, will affect the use of towels in the future.

Step 3: Wringing And Drying

After rinsing clean, gently squeeze out excess water. Note that my word is “gently squeeze”, don’t twist or pull the towel as hard as twist twist, it will break the fiber. Finally, hang them in a ventilated place to dry naturally.
