What is the difference between cleanroom wipers and regular wipes?

Cleanroom wipers are specifically designed for controlled environments with ultra-low particle generation and lint-free properties. They undergo special washing and packaging processes in ISO-certified facilities, unlike regular industrial wipes.

Do cleanroom wipers have a shelf life?

Yes, cleanroom wipers typically have a shelf life of 2-3 years when stored in original packaging in a cool, dry environment away from direct sunlight.

What ISO class are your cleanroom wipers compatible with?

Our cleanroom wipers are compatible with ISO Class 4-8 environments. We provide detailed particle count data and certification for each product grade.

Cleanroom Wiper Real Test: 180g vs 105g – 100 Data Points Tell You Which One to Choose

What Is GSM and Why It Matters

GSM stands for grams per square meter. A 180g wiper is thicker, denser, and more durable than a 105g wiper. It also costs more. The 105g wiper is thinner, softer, and more economical but slightly less abrasion‑resistant.

The key question: Do you really need the heavier wiper on your line

We tested both. Here is the data.

Real Test Data 180g vs 105g

Test conditions Same batch of 80/20 microfiber, ultrasonic edge seal, DI water pre‑laundered, cleanroom packaged. 10 samples per test, median values reported.

1. Particle Shedding (≥0.5μm, particles/m²)

Weight	Test 1	Test 2	Test 3	Average	ISO 5 reference limit
105g	210	225	218	218	≤300
180g	165	172	168	168	≤300

Conclusion Both pass the ISO 5 limit easily, but the 180g wiper sheds about 23 percent fewer particles. For ISO 5 and above precision wiping, 180g is safer. For ISO 6‑8, 105g is sufficient.

2. Absorbency (DI water, g/g)

Weight	Absorbency	Standard deviation
105g	18.2	±1.2
180g	24.5	±1.5

Conclusion The 180g wiper absorbs about 35 percent more liquid. If you frequently clean up spills or need to absorb large amounts of solvent, choose 180g. For light IPA wiping or minor stains, 105g works fine.

3. Abrasion Resistance (after 200 wiping strokes, surface fuzzing)

Weight	Surface condition after 200 strokes	Particle shedding increase
105g	Visible fuzzing, slight edge damage	+78%
180g	Mild fuzzing, edges intact	+22%

Conclusion If you reuse a wiper multiple times (e.g., cleaning several parts of the same equipment), 180g lasts much longer. 105g is best for single‑use applications.

100 Data Points Summary Which One to Choose

Application	Recommended weight	Reason	Cost advice
Wafer / lithography chamber wiping	180g	Lowest particles, no lint, high absorbency	Do not save
PCB cleaning before reflow	105g	Clean enough, low cost, single use	Save
Equipment exterior / machine wiping	105g (can reuse 2‑3 times)	Economical, low abrasion demand	Save
Large liquid / oil spill cleanup	180g	High capacity, fewer wipers needed	Do not save
Optical lens / precision mold	180g (microfiber)	Scratch prevention, tightest particle control	Do not save
General lab cleaning	105g	Best value	Save

Frequently Asked Questions

Q Does the 105g wiper shed more particles
A Based on our data, 105g shedding is still well below the ISO 5 limit (≤300). For ISO 6‑8 it is perfectly fine. For ISO 5 core areas, use 180g.

Q Can I mix both weights in one order
A Yes. Many customers segregate by zone – 180g for core cleanroom, 105g for support areas. We support mixed orders.

Q Can 105g wipers be reused
A Not recommended. 105g has moderate abrasion resistance. On second reuse particle shedding increases by about 70 percent. 180g can be reused 1‑2 times in non‑critical areas.

Why Particle Data Matters More Than the Packaging

The Test Method We tested three swab types from three different suppliers. All swabs were labeled as cleanroom grade. The test method followed IEST‑RP‑CC004.3 for liquid particle counting. Each swab was extracted in DI water and the extracted particles were counted using a laser particle counter. Swab type Head material Bonding method Claimed cleanroom class

Do Your Anti‑Static Gloves Actually Work The Simple Test Most Factories Skip

The Test Data What We Found We tested 50 pairs of anti‑static gloves from operators on SMT and PCB assembly lines. All gloves were labeled as ESD safe. The test method followed ANSI ESD STM11.11. We measured resistance from the outer coated surface to the inner lining. Glove age Number tested Pass rate Fail rate

Why Your ESD Shoes Fail Earlier Than You Think And How to Make Them Last

The Test Data What We Found We tested 100 pairs of ESD shoes from operators on electronics assembly lines. Each shoe was tested using a footwear tester. The operator stood on a metal plate while wearing the shoe with their normal socks and insoles. Shoe age Number tested Pass rate Fail rate 0‑3 months (new)
