Hotel linens, especially white ones, require regular whitening treatments to maintain their freshness and elegance. While bleaching is essential, over-reliance on it may not fully eliminate yellowish or brownish stains from sunlight exposure. Here’s how to improve linen brightness:

Bleaching:
Stain Removal: Oxidizes stains that washing alone can't remove.
Whiteness: Enhances fabric brightness.
Process: Pre-wash, rinse, then bleach for tough stains.
Bleaching Time:

Effective bleaching occurs within 6-8 minutes. Longer exposure doesn't improve results. Ensure chlorine concentration in wastewater is under 10ppm.

Temperature:
Chlorine bleach: Best below 65°C to avoid fabric damage.
Oxygen bleach: Works best at 70°C–90°C. A 10°C increase cuts bleaching time in half.
pH Control:
Chlorine bleach: Ideal pH is 10.2–10.5. Avoid acidic or neutral pH to prevent fabric weakening.
By managing these factors—bleaching time, temperature, and pH—hotels can keep linens bright and durable.
