I cleaned my gas stove using a product called 'exit mould'. It contains Sodium Hydroxide, alkaline salts and Sodium Hydrochlorite.

The stove now emits a green flame when i light it.

Am I likely to blow myself up if I leave it on? Should I light it again and leave it burning until the flame goes back to blue?
