When sharing an apartment or living in a dorm, the most annoying things are yellowed white shirt collars and darkened T-shirt cuffs. Throwing the whole garment into the washing machine might not get it clean and wastes water. This Kao enzyme foam collar cleaner from Japan is specifically designed to tackle these localized stubborn stains. No need to scrub hard; just spray it on, let it sit for a while, then throw it into the washing machine, and it will break down old sweat stains and grease.

It's not a pungent, strong chemical agent. Instead, it uses enzyme components to gently break down dirt. The foam texture adheres tightly to collars and cuffs without immediately running off, giving the cleaning agents enough time to work. For students who are busy with deadlines and don't have time to hand wash, or who don't want to discard a garment due to a small stain, this is a secret weapon for maintaining a presentable appearance with minimal effort.

• 【Enzyme Decomposition Technology】Targets protein-based stains (like sweat and sebum), breaking down dirt from deep within the fibers rather than just covering it, addressing the recurring problem of yellowed collars.
• 【Dense Foam Retention】Sprays out as a dense foam that can adhere vertically to surfaces like collars and cuffs without running, ensuring continuous penetration of the cleaning agents, ideal for localized spot cleaning.
• 【Effortless Pre-treatment】Simply spray before washing, no need for vigorous manual scrubbing. Can be machine washed directly, saving handwashing time and effort, and protecting garment fibers from damage.

Use Cases: Suitable for yellow stains on white shirt collars, dark marks on school uniform cuffs, strong sweat odors on athletic wear, oil splatters from hot pot, and other localized dirt; especially suitable for renters and international students for quick daily garment care.

Product Specifications: Standard Japanese Kao product, foam spray type, suitable for all washable garments.

Usage Tips: Spray directly onto the stain on dry clothing, let it sit for 5-10 minutes for the foam to penetrate, then proceed with regular machine or hand washing; do not use on delicate fabrics such as silk or wool.
