Refreshing dry ribbons:Take a little bottle, fill it with refreshing solution.The violet little thing is a piece of sponge covered by a tissue of textile.So the refreshing solution flows gently through the mouthing of the bottle onto the ribbon.Refreshing solution:- 3 parts pure rubbing alcohol - 1 part castor oil- when needed add oil based stamp ink to darken the ribbon

Small bottle used as applicator with a sponge inserted on the top covered by a small square of cloth which is rubberbanded on. This is then applied slowly to the typewriter ribbon on a winder.
