If you love a beautifully scented home, you likely have a stash of wax melts. But do they actually go off? Can they lose their scent strength if they sit in a drawer for too long? In this guide, we will break down the truth about wax melts. We will also look at a mess-free alternative called scented sizzlers that might just change the way you scent your home.
Do Wax Melts Have a Use-By Date?
The short answer is no, wax melts do not rot or go mouldy like milk or bread. However they do lose their scent power over time.
Think of a wax melt as a mix of wax and scented oil. These two parts do not actually bond together forever. Instead, the oil is trapped inside the wax. Over time, that oil can evaporate or change, leading to a weaker smell.
How Long Do They Last And Do They Have A Best Before Date/Use By Date?
In the UK most home fragrance experts suggest using your melts within these times, there are however no exact best before dates:
Soy and Natural Waxes – 6 to 12 months for the best scent.
Paraffin Waxes – Up to 24 months, as this wax holds onto oil a bit tighter.
3 Signs Your Wax Melts Have Gone Off
You don’t need a lab to tell if your wax melts are past their best. There are a few simple signs to look out for. First is the sweat test. If you notice small oily beads on the surface, it usually means the fragrance oil is starting to separate from the wax. Then there’s the fading look. If a once bright colour like pink or blue has turned dull or slightly yellow, that’s a clear sign it’s aged. Finally, trust the sniff test. If the scent is barely noticeable when the wax is cold, it’s unlikely to give you much fragrance once melted.
Are Old Wax Melts Safe?
Old wax melts are generally safe to use. They won’t explode or become toxic just because they are old. The main risk is just disappointment. You’ll be using up a tea light and heating your home for a scent that isn’t there.
How to Keep Your Melts Fresh
To make your wax melts last as long as possible, stick to three simple rules. Keep them in the dark, as sunlight can fade both the scent and the colour, so a cupboard is ideal. Keep them cool by avoiding places like near an oven or radiator or storing in a bathroom, where heat and moisture can affect the fragrance. Keep them airtight by storing them in a sealed bag or clip top jar, which helps prevent the scent from escaping into the air.
Simple FAQ
Can I use old wax melts?
Yes, but they might not smell of anything. It’s better to replace them if they are more than a year old than be disappointed and waste a tealight although there’s no harm trying them.
Why can’t I smell my wax melt anymore? It could be nose blindness (you’ve just got used to it), or the wax might be spent. If the wax has been melting for more than 4-6 hours, the fragrance might be gone.
How do I clean my burner? For wax, wait until it’s slightly warm and pop it out or use cotton balls to soak up the liquid. For scented sizzlers, just wait for them to cool and pour them out.
