4. Utilize different parts of the LOOY cloth for even usage, including the unused sections, backside, and edges.

LOOY is a natural dry product that does not require significant moisture to be effective.

Dry products, unlike wet ones, have several advantages :

IPA content in moist products may damage lens coatings, leading to loss of functionality.

Wet products leave liquid droplets, making it difficult to wipe them clean.

Dry products offer superior effectiveness, duration, usage frequency, and durability compared to moist products.
