What is GSM in microfiber cloths?
GSM stands for Grams per Square Meter, or the weight per square meter of the cloth. It indicates how tightly and heavily the microfibers are woven.
Low GSM (200–400): Thin, light cloths that become saturated quickly and primarily displace water rather than absorb it.
Medium GSM (600–900): Suitable for light drying, but may cause streaks and water spots if there is a lot of water on the paint.
High GSM (1000–1500+): Thick, super absorbent and soft – ideal for quick, safe and streak-free drying.
Why GSM determines your car wash results
The density of your cloth directly determines how well you remove water from the paint and how safely you do so:
Absorption capacity
A higher GSM can absorb liters of water without becoming saturated. This means you won't have to wring out the cloth as often, and the paintwork will stay protected.
Safety of the paint
Thick microfibers pull dust and dirt deep into the cloth, away from your paintwork. This prevents scratches and swirl marks.
Faster drying time
By absorbing more water at once, you dry your car faster and more efficiently.
Our AURUX 1300 GSM drying cloth is a perfect example of a cloth that combines all these advantages: it can absorb up to 3 liters of water, traps dust and microparticles, and provides a streak-free, glossy finish.
