Astonish paste is a specialist cleaner made with no harsh chemicals, perfect for removing grease and burnt-on food. Astonish paste is abrasive. Care is needed on delicate or polished surfaces to avoid scratching. If using on old or damaged enamel, test compatibility on a small area first. Dampen the Astonish paste applicator with warm water and use to apply the cleaning paste in gentle circular motions. Rinse the applicator and reapply where necessary. Rinse and wipe clean surfaces using warm water and the sponge side of the applicator.
