These instructions are just to keep your smelly jelly working for up to 5 years. NOTE- These instructions will not help you to create a smelly jelly from scratch as these are made. Always use DISTILLED water – never use tap water - As your jelly starts to shrink you may add more distilled water. Once the scent is no longer strong enough add more fragrance oil. To keep your smelly jelly from becoming moldy it is a good idea to add a tablespoon of alcohol every time you add water. DO NOT GET THEM IN YOUR DRAINS –But if you have accidentally put them in drains add lots of salt to the drain SALT MELTS SMELLY JELLIES. PLEASE NOTE: If you think your smelly jelly is not working in a room - Walk out of the room to the outside take a deep breath and then come back in chances are your senses have gotten use to the fragrance and once you come back in you will again be able to sense the fragrance in the air. For a more intense fragrance release place on a candle warmer or coffee cup warming plate.
