The HG oven & grill revamp kit is a complete kit that will make your oven, grill, baking trays, barbecue grills and planchas look like new. The extremely strong soaking gel, which is applied with the supplied special brush, removes even the most difficult baked-in baking stains effectively. This unique gel formula has been developed especially for long soaking, without drying out, on vertical surfaces. This ensures that difficult burnt-on baking stains on oven walls or grills can be removed effectively. Apply the gel from the HG oven & grill revamp kit liberally to the surface with the special supplied brush. Leave the gel to work for 5 to 30 minutes. The dirtier the surface, the longer the gel should be left to work. Then wipe it off with kitchen roll or a damp sponge. Finally remove any residues thoroughly with water.
