Remove loose carbon with a scraper. Warm oven to between 40C - 60C. Switch off oven before application. Spray directly onto surface, leave for minimum 5 minutes contact time and wipe clean. For heavy burnt on carbon leave to stand for longer periods.
Oven & Hob Cleaner works as a result of its excellent ability to lower surface tension, penetrate soils, boost solvency, couple hydrophobic greases and oils: effectively emulsifying and lifting them free from surfaces. Oven & Hob Cleaner allows soils and burnt residues to be quickly and easily wiped or scoured and rinsed away, enabling complete removal from surfaces.
