New and Improved! We discovered our older cloths could release some of the absorbent "beads" if excess pretreatment was applied so we have sourced a better product! These new low-lint cloths are 100% cotton and meet ISO Class 5 (Class 100) and above Cleanroom requirements for critical pharmaceutical, medical device, and semiconductor applications. Product is a 5 pack of low-lint and absorbent cloths. Each cloth is folded to 5" x 5" (13 x 13cm) and can be unfolded to up to 20" x 20" or used folded. The cloths are cut to shape as necessary or as shown in the videos below and use to absorb water spot pretreatment. The cloths are excellent for water spot removal from refractors and SCT corrector plates.
