(1) Check the whiteness and cleanliness of the linen. When entering the hotel room, first check the sheets and covers to see if they are clean, bright white, and free of stains, especially if the pillowcases and covers have turned yellow. If they have turned yellow or if the overall color has turned yellow, it indicates that the linen has not been cleaned, or the water quality is not up to standard, and the rinsing is not thorough.
(2) Flatness of bed sheets and duvet covers. The duvet cover is double-layer, and during the flattening process, the employee's upper layer is uneven, and the flattening machine is adjusted unevenly, which can cause wrinkles on the duvet cover, poor experience, and affect its appearance.
(3) Touch to see if it is soft. Hotel linen is mostly made of pure cotton material, which is warm, comfortable, and has good breathability. If the fabric feels hard and astringent to the touch, it indicates that the pH value of the fabric exceeds the standard, with high alkalinity, neutralization, and incomplete rinsing.
(4) Towels, bath towels, fluffiness and whiteness. Pure cotton towels and bath towels have a lot of fluff on the surface. After cleaning and drying, the fluff is full and comfortable to wipe hands and face. If it is not fluffy, hard, or yellow, it indicates high alkalinity, excessive pH value, incomplete rinsing and neutralization, or too long drying time causing the towel to become hard.
