Question 1

I have a unique product requirement. Can you develop a custom product?

Accepted Answer

Yes, WIPESTAR develops custom products. Please CONTACT US to discuss your product requirements.

Question 2

Is there a quality difference in products from USA, Asia and Europe?

Accepted Answer

No, WIPESTAR implemented a global quality system which is valid for every factory.

Question 3

Can I find lint-free wiper?

Accepted Answer

There is no absolute lint-free wiper available worldwide. Lint-free is always a subjective view of expectations according to the point of use of the wiper. Minimizing the risk of contamination by the wiper is key. We can help you to find the best product according to your need. Please contact us for more information.

Question 4

Why is proper cleaning important in Cleanrooms and Controlled Environments?

Accepted Answer

According to the Institute of Environment Sciences and Technology (IEST) cleaning is most important element in contamination control and preventing contamination issues in cleanrooms and controlled environments.

Question 5

Are your products just for Cleanrooms?

Accepted Answer

Our products can be used in Cleanrooms but also other controlled environments and across many of industries such as industrial manufacturing environments, labs and other scientific environments.

Question 6

Do you offer samples of your products?

Accepted Answer

We offer free samples of nearly all of our products. You can learn more about how to request a sample by emailing us: info@wipestar.com

Question 7

What is a Cleanroom?

Accepted Answer

A cleanroom or clean room is an environment, typically used in manufacturing, including of pharmaceutical products, scientific research, and microelectronics with a critically low level of environmental particles and pollutants such as dust, aerosol particles, chemical vapors, and other airborne particles and microbes.

Question 8

What are cleanroom wipes?

Accepted Answer

Cleanroom wipes, also known as cleanroom wipers, are specialized cleaning materials used in environments that require high levels of cleanliness and contamination control.

Question 9

What is the No.1 source of contamination in a cleanroom?

Accepted Answer

People are typically the number one source of contamination in cleanroom environments, therefore having the proper standard operating procedures and practices in place is of paramount importance.

Question 10

What is the difference between cellulose and polyester wipes?

Accepted Answer

Cellulose wipes offer high absorbency, while polyester wipes provide strength and low lint. Learn more about our cellulose polyester wipes and why the blend matters for industrial cleaning performance.

Question 11

What cleanroom ISO classes do WIPESTAR cleanroom wipes cover?

Accepted Answer

WIPESTAR cleanroom wipes are available for ISO Class 5 through ISO Class 8. Laser-sealed and ultrasonic-sealed polyester/microfiber wipes are rated for ISO Class 5-6. Heat-sealed wipes cover ISO Class 7-8. Cut-edge and general-purpose non-woven wipes are suitable for ISO Class 8-9 and non-rated industrial environments.

Question 12

How many times can industrial wiping cloths be reused?

Accepted Answer

Reusability depends on the wipe material, contamination profile, and wash protocol. Microfiber wipes can withstand 200+ wash cycles. Knitted polyester wipes are reusable for 50+ cycles. Spunlace non-woven wipes like the W2101 are generally designed for single-use in contamination-critical applications.

Question 13

Can WIPESTAR wiping cloths be used with isopropyl alcohol (IPA)?

Accepted Answer

Yes. All WIPESTAR wiping cloth materials — polyester, rayon/polyester, cellulose/polyester, polypropylene, and wood pulp/polypropylene — are fully chemically compatible with isopropyl alcohol, acetone, and most common industrial solvents.

Question 14

Which wiping cloth material is best for heavy oil and grease removal?

Accepted Answer

Cellulose/polyester mesh wipes — like the WIPESTAR W3501 Heavy Duty Surface Preparation Wipe (80 GSM, Mesh pattern) — are purpose-built for heavy oil and grease removal. The mesh texture increases mechanical friction while the high cellulose content provides extraordinary fluid retention.

Question 15

What does GSM mean for industrial wiping cloths?

Accepted Answer

GSM (grams per square meter) measures the areal density — or thickness/weight — of the wipe fabric. Higher GSM wipes (e.g., 80 GSM W3501) are thicker, more absorbent, and more durable, ideal for heavy-duty degreasing. Lower GSM wipes (e.g., 65 GSM W3401) are softer and more flexible, preferred for surface-sensitive precision cleaning.

Question 16

What is the difference between cut-edge and sealed-edge wiping cloths?

Accepted Answer

Cut-edge wipes are mechanically trimmed and generate loose fibers during use. Sealed-edge wipes (laser, ultrasonic, or heat-sealed) fuse the fabric edges during manufacturing, dramatically reducing fiber shedding. For any cleanroom or precision application, sealed-edge wipes are essential.
