1. Do a good job in the classification of linen in old and new hotels. The natural damage and abnormal damage of linen in old hotels should be treated differently, and the dehydration time of linen in old and new hotels should be different with different strength. 2. Avoid direct contact between cotton fabrics and chemicals with strong acidity or corrosiveness; 3. Care should be taken in the conveying process of linen in guest rooms to prevent secondary pollution and accidental tearing; 4. The detergent must be used properly, the charging time and temperature should be appropriate, the characteristics and use of the detergent should be understood, the residual chlorine should be removed with dechlorination agent in time, and the residual alkali should be neutralized with neutralizer; 5. Avoid "fatigue use", that is, washing many times on the same day. If this continues every day, the service life of linen in the guest room will be shortened. Let it have enough rest time, at least for more than 24 hours, that is, after washing, take a day off and use it the next day; 6. Do a good job of sorting before washing, including sorting of linen types and separation of sundries; 7. Before washing operation, empty machine should be used to check whether there are sharp and iron sundries left in the drum of the machine; 8. Check the machine frequently to prevent secondary pollution and man-made damage. The loading capacity should be appropriate (81%~85%) when washing. Too much or too little will affect the cleanliness and wear of linen.
