Our Simmer Crystals are used in the same way as a wax melt.
Pop 1-2 teaspoons in your burner and heat as normal. The oil will evaporate and create a strong & instant fragrance within your home - the crystals do not melt or evaporate. Once the scent has run out simply dispose of the crystals and they will leave a mess-free burner.
PLEASE NOTE -
The crystals contain colouring that may stain any soft furnishings or clothes if they come into contact with them.
