Maintaining the whiteness of garments necessitates specific care and attention:

• Separate Washing: Launder white garments separately from colored or dark apparel to mitigate the risk of color transfer and minimize potential staining.

• Employ Appropriate Detergents: Opt for laundry detergents or additives explicitly formulated for white fabrics. Ensure compatibility with garment materials to avert fiber damage.
  
  
• Exercise Caution with Bleaching: Approach bleach usage judiciously to prevent overexposure, a potential catalyst for yellowing. Adhere strictly to bleach product instructions or consider alternative solutions such as oxygen bleach.

• Timely Stain Management: Swiftly address stains using suitable stain removers to preclude setting and reduce the risk of yellowing.

• Natural Air Drying: During the air-drying process, circumvent prolonged exposure to direct sunlight, as UV rays can expedite yellowing. Opt for shaded areas or utilize indoor drying methods.

• Storage Protocols: Refrain from storing white clothing in plastic bags to prevent moisture entrapment. Ensure garments are thoroughly dry before consigning them to storage 

These guidelines should contribute to the preservation of garment whiteness, minimizing the prospect of yellowing.
