For glass already stained/discoloured, the ClearShield System restores the surface to its original and ‘as-new’ appearance. Then, after the glass is converted into ClearShield ‘Non-Stick’ Glass, a simple and economical after-care programme is recommended. The after-care programme keeps ClearShield ‘Non-Stick’ Glass looking and performing like new for life – keeping its promise of visibility, clarity and cleanliness.
