We always bought the sofa zigzag spring from the sofa materials Shop or the sofa spring factory.As the wholesaler or the Sofa manufacturers,do you know how to keep them long time,and prevent them to be antirust?
1. Put them in the dry environment,without the wapour,,not the dark place.
2. Packing them well,put them inside the airtight bags,make sure without any air.
3. When you use inside the sofa,,you must cover the non-woven or fabric,so that it can keep dry.
If the spring was rusty,you can sprinkle a little machine oil on it,so that it can prevent them to continue to be rusty.
