Beeswax wraps in the oven: freshen up or re-wax

A beeswax wrap that no longer sticks is rarely worn out. Usually the wax has just gone uneven. The oven on a low heat puts the sheet right again in a couple of minutes.

Short answer: Lay the sheet between two sheets of baking paper and give it about 2 minutes in the oven at 80 to 90 °C. The wax melts down, spreads out evenly, and the cling comes back. If it has gone completely, scatter grated beeswax from a wax block over the sheet first, and repeat until the wax has soaked in.

How to tell which level your sheet needs

There are two levels, and most sheets only need the first. Feel the sheet before you switch the oven on.

Sign on the sheet	What it means	What to do
Sticks poorly, but looks even	The wax has set unevenly	Freshen up, level 1
Pale streaks along the fold lines	The wax has cracked where the sheet folds	Freshen up, level 1
Dry and stiff, water soaks in	There is little wax left	Re-wax, level 2
Large matt patches with no sheen	The wax is gone there	Re-wax, level 2
The fabric is worn thin and gives way	The cotton is finished	Cut it up and compost it

Level 1: freshen the sheet up in two minutes

This is the job you will do most often, and you add no new wax. You are only melting down the wax that is already in the fabric. You need an oven, a baking tray and two sheets of baking paper.

1
Heat the oven to 80 to 90 °C
Beeswax turns liquid at around 62 to 65 °C, so no more is needed.
2
Lay the sheet between baking paper
Baking paper on the tray, the sheet flat on top, baking paper over. Then the wax ends up in the sheet and not in the tray.
3
Into the oven for about 2 minutes
Stay and watch: once the sheet has an even, glossy sheen, the wax has melted down.
4
Peel the top sheet of baking paper off straight away
Wait until everything is cold and the paper sticks fast.
5
Cool the sheet flat
Lift it by one corner and lay it down flat. After half a minute it is ready.

Level 2: a full re-wax with grated beeswax

If the sheet has lost its cling altogether, melting it down is not enough. Then you have to add wax. You need a wax block, a grater, baking paper and the same tray.

1
Wash the sheet in cold water and let it dry completely
Grease and crumbs left behind get baked in under the new wax.
2
Grate the beeswax on the finest side of the grater
Finely grated wax melts evenly. Large pieces leave lumps.
3
Scatter the wax thinly over the sheet
Spread it sparsely across the whole surface. Use less than you think, you can always add more.
4
Baking paper over, into the oven at 80 to 90 °C
Leave it until the wax has soaked in. You can see it happen: the dark patches spread out and even up.
5
Top up wherever it is still dry
If an edge or a corner is matt, scatter a little wax just there and put the sheet back in.
6
Cool the sheet completely flat
Do not fold it before it is cold. The wax sets in under a minute.

Common mistakes when re-waxing beeswax wraps

Too much heat. Ordinary baking temperatures melt the wax out of the fabric and down into the tray instead of into the fibres.
Too much wax. A thick layer makes the sheet stiff and tacky, and it collects crumbs. Thin and even is the goal.
Folding too soon. Fold a warm sheet and the wax cracks along the fold straight away.
The wrong wax. Use pure beeswax. Candles and paraffin have no place on anything that sits against food.
Forgetting the baking paper. With no paper above and below, the wax sticks in the tray.

The routine between renewals counts just as much. It is gathered in the guide on caring for beeswax wraps.

How many times can a sheet take this

Freshening a sheet up you can do as often as you like. The heat is low and nothing wears out. Many people take the whole set a couple of times every six months. A full re-wax is something most sheets need once or twice a year.

It is the fabric, not the wax, that decides in the end. Once the cotton is worn thin or full of holes, new wax will not hold. Then the sheet is finished: cut it up and put it in the compost. It is cotton, beeswax and tree resin, so it turns into soil. With regular use that happens after about 12 months. The sums are in the article on whether beeswax wraps are worth it, and everything the sheets can be used for is in the guide to using beeswax wraps.

The bread bag is not renewed in the oven

This is the most common mix-up: the oven method is for the sheets, not for the beeswax bread bag.

The bag is re-waxed with a pan and a brush: melt pure beeswax in a bowl set over boiling water, brush it on thinly and evenly, and hang the bag up to dry. The oven and an iron are not recommended for the bag. The method is in the guide on re-waxing the beeswax bread bag. It works the other way round too: a pan and a brush is not the method for the sheets.

Frequently asked questions

How hot should the oven be?

80 to 90 °C. Beeswax melts at around 62 to 65 °C, so no more is needed. Higher heat drives the wax out of the fabric and down into the tray.

Do I have to add new wax every time?

No. Most sheets only need melting down. You reach for new wax when the sheet is dry and stiff and will not stick at all.

Can I use the microwave instead?

No. Beeswax wraps should never go in the microwave, whatever the setting. The heat is uneven and far too high in spots.

The sheet turned tacky, what do I do?

Then there is too much wax on it. Put the sheet between two clean sheets of baking paper at 80 to 90 °C for one minute. The paper soaks up the excess. Cool it flat.
