The water, or rubbing shot, if the various approaches have been tried yet. Maybe the thinking of changing the sofa cushion.
Add the active softener to the warm water and soak it for 1-2 hours (not rinse, because the softener is used after washing) and then dry. In use, it is best to use the other side of the sponge in turn, so that the reverse action of the fiber will help prolong the sponge's use.
The most scientific and labor-saving way is to use artificial recovery when not in use. For a long time, the sponge pad will automatically recover.
