Shannon Lush.
1. First clean the surface with bicarb soda and white vinegar (and an old toothbrush to penetrate the nooks and crannies).
2. Then grate white candle wax in a bowl and apply it to the crack and melt with a heat gun – you can buy these for $20 from hardware outlets.
3. Push it in evenly using a finger wrapped in a cloth. Remove any excess with a knife. Wax is cheaper than silicone and mould won’t grow behind it easily.
