Description

Foam cleanroom wipers are used for precision cleaning in controlled environments. They help remove particles while supporting contamination control in sensitive applications.

These wipers are made from reticulated polyurethane foam. The open-cell structure provides high absorbency and helps trap particles during cleaning.

They are designed to minimize particle shedding, making them suitable for ISO Class 5 environments such as microelectronics, laboratories, and cleanroom manufacturing.

The soft, non-abrasive material is safe for delicate surfaces. Even when wet, the foam maintains strength and durability.

The compact 2″ x 2″ size makes these wipers ideal for detailed cleaning and small, precise areas.

Key Features

• Rated for ISO Class 5 cleanroom environments
• Made from reticulated polyurethane foam with 100 pores per inch for superior particle trapping and fluid absorption
• Open-cell structure absorbs liquids quickly while minimizing particle shedding during use
• 1/4″ thickness provides body and structure while remaining soft and non-abrasive
• Maintains strength and durability even when fully saturated
• Compact 2″ x 2″ size designed for detailed, precision cleaning of small and tight areas
• Can also serve as light cushioning or vibration dampening for delicate components
• Packaged 300 per bag, 5 bags per case (1,500 wipers per case)

 
Common Uses

• Precision spot cleaning of small components and tight spaces in ISO Class 5 environments
• Screen and surface cleaning in microelectronics manufacturing and assembly
• Solvent application and removal in areas where a larger wiper would be impractical
• Semiconductor and flat panel display cleaning at the component level
• Optical component and lens cleaning requiring a soft, non-abrasive contact surface
• Pharmaceutical and medical device assembly area precision cleaning
• Light cushioning and vibration dampening for small, delicate parts during handling
• Swab-style cleaning tasks where more surface area and absorbency than a swab is needed

 
Who This Is For

The 2″ x 2″ foam wiper is the precision tool in the foam wiper lineup, designed for technicians who need the same ISO Class 5 rated performance as the 6″ x 10″ version but in a compact format suited to detailed, close-in work. It is particularly well suited for microelectronics assembly, optical work, and any application where a standard-size wiper is simply too large to work effectively in the available space. The high per-case count of 1,500 makes it a practical choice for facilities that use small foam pads at high volume throughout the day. If your team works with both large surface cleaning and detailed component work, pairing this with the 6″ x 10″ foam wiper covers both tasks within the same product family.

FAQ

How is this different from the 6″ x 10″ foam wiper also available in this store?
The material, construction, and ISO Class 5 rating are identical. The only difference is size. The 2″ x 2″ wiper is designed for precision spot cleaning of small components, tight spaces, and detailed areas where a larger wiper would be awkward or wasteful. The 6″ x 10″ wiper is better suited for larger surface areas and screen cleaning applications.

What is reticulated polyurethane foam?
Reticulated foam is an open-cell foam where the membranes between cells have been removed, leaving a highly porous skeletal structure. This gives it exceptional absorbency and particle-trapping capability. At 100 pores per inch, these wipers have a fine, uniform structure well suited to precision cleaning in controlled environments.

Are these wipers safe for delicate surfaces and components?
Yes. The foam material is soft and non-abrasive, making it safe for screens, optical surfaces, and sensitive electronic components that could be scratched or damaged by knit fabric wipers.

Can these wipers be used as cushioning or padding?
Yes. The resilient 1/4″ foam construction can be used to reduce vibration and cushion small, delicate components during handling or process steps, which is a useful secondary application in electronics and precision manufacturing environments.

Are these wipers compatible with solvents and cleaning solutions?
Yes. These wipers have good sorptive capacity and work well with a range of solvents and cleanroom-approved cleaning agents. The foam maintains its structural integrity when wet. Always verify chemical compatibility with your specific cleaning agent before use.

How many wipers come per case?
Each bag contains 300 wipers and each case contains 5 bags, for a total of 1,500 wipers per case.

How do these compare to cleanroom swabs for small-area cleaning?
Both are designed for precision cleaning in tight spaces, but foam pads offer more surface contact area and higher fluid absorption than a swab tip. Swabs are better suited for very narrow openings, connectors, and pinpoint cleaning tasks. The 2″ x 2″ foam wiper is a better choice when you need to clean a small but flat or slightly larger area with more fluid control.
