Information on this web page explains the use of beeswax for lining, coating or sealing utensils for use in preparing kefir, or for brewing in general. Melted beeswax can be used to line the meshing of metal or wooden strainers, coat the inner surface of lids of jars and to line wooden utensils intended for stirring kefir. You can seal wooden boards for preparing non-mold varieties of kefir-cheeses. Beeswax can also be used to seal terra cotta, ceramic or stoneware crocks or plastic pots. This natural method of sealing utensils is useful in various ways.
NOTE it is important that any beeswax used for sealing is of high quality obtained from a reputable source. Paraffin wax can not, and must not be used in place of beeswax!

How this can help
Forms a protective barrier between the kefir grains and the metal meshing of metal strainers [as a chemical barrier and an electrical insulator].
Keeps the strainer reasonably sterile due to the bacteriostatic property of beeswax.
Ease in cleaning the strainer; by simply running cold to warm water over the strainer [hot water softens or melts beeswax, so plain cold or warm water without any detergent is best to use = less energy = less pollution = less cost].
How to line or coat metal sieves with beeswax
Heat the metal meshing of the sieve either with an electric hot air gun, or by holding the strainer high over a naked gas flame. Rub a small block of beeswax over the heated mesh. While rubbing, the heated meshing will melt amounts of beeswax onto the meshing itself. Re-heat the meshing with the hot air gun or by holding the strainer high over a naked flame, to further melt the beeswax and to force an even layer of wax over the surface of the mesh. Dip a piece of cotton in some melted beeswax, then smear the meshing with the waxed-cotton material. A rubbing or wiping action should ensure a thin layer of beeswax should cover the entire surface of the mesh, doing so on both sides of the sieve.
Some strainers have an opening where the mesh is fixed to the outer rim of the strainer. In this case, the opened space is quite difficult to keep clean, and amounts of kefir and other food particles can easily become entrapped in the crevice or channel. Food particles entrapped within the outer rim of such strainers, can propagate unwanted weed microorganisms. I find that such areas can easily be plugged shut, by hand-forcing small amounts of warm, softened beeswax into the opening. This will seal the area, and reinforce the strainer making it a bit stronger.
Form a protective non-reactive chemical-barrier between any plastic or metal lids, which have a rubber inner lining that perishes.
Prevents inner surface of metal lids from oxidizing [rusting].
Reduces the risk of weed micro-organisms from propagating within the lid, due to the bacteriostatic property of beeswax.
Can increase sealing capacity of lids. This is favourable for preparing water-kefir, due to the brew retaining carbon dioxide to produce a sufficient amount of carbonation, instead of the gas escaping through the lid, due to an insufficient seal.
Jar lids are easily lined with a layer of beeswax. Although the photos below demonstrates a plastic lid, the same treatment can be used for lids made from metal.
Add about 1cm [1/2 inch] of water in a suitable pan such as a skillet. Float the lid in the hot water with inner lid facing upward, and then heat the water to a slow boil. Pour melted beeswax into the lid and then move the lid around in the hot water bath with a pair of salad fingers, to force an even layer of melted beeswax over the entire surface of the lid.
Remove the lid from the hot water bath, and place lid on a cold surface to set the beeswax as it cools. That's it--- beeswax lined lid!
Note the brown speckles in the beeswax lined lids is propolis, a natural antibiotic. The beeswax in this case was collected from a wild beehive which swarmed in our garden and settled in a large bin. The bees made their entry through a small hole in the lid of the bin, and they created a wonderful honeycomb on the underside of the lid, hanging downward in the bin, in a beautiful arrangement. One day, the wild honey comb melted from the lid, and fell to the bottom of the bin due to a heat wave we experienced at the time. The bees left the hive and collected all the honey from the wild hive as they found a cooler place for their new hive. I kept the propolis with the beeswax that they left. It was lovely to watch them do their work. Thanx for the free honeycomb, guys!
Wooden utensil used for handling kefir grains, or for string kefir can be treated with beeswax. This includes sealing wooden boards used for drying cheese such as kefir-cheese can be treated with beeswax. This is especially useful when preparing kefir-cheese not intended to be cultured with mold.
Placing the wooden utensil [such as pine wood drying boards, wooden spoons or bamboo steamers used as a cheese form] in an hot oven preheated to 100°C [210° F] for 20 minutes. Remove the utensil and then smear or rub beeswax over the entire surface of the wooden utensil. The waxed wooden utensil may be passed over a naked flame, or heated with an electric hot air-gun or good hairdryer to ensure that an even layer of beeswax is melted over the entire surface of the utensil. Let utensil cool to room temperature to set the beeswax.
To add to the land of milk, honey and beeswax, directions for treating cloth with beeswax is explained next. This is useful for individuals who use cloth to cover their kefir-making jars. Cotton, linen, silks or rayon material, including nylon [the material used for curtains e.g.] can be treated with beeswax.
seal the material so less to no air, dust, microbes and molds find their way into the kefir.
waterproof the material.
render the material bacteriostatic and fungistatic [prevents the growth of bacteria, yeasts and mold on the material itself].
help to reduce chemical reactions between certain nylon material and the acidic component of kefir.
reduce energy cost and eliminates the use of detergent [simply wash the waxed cloth with warm or cold water].
How to treat natural fibers [including nylon fibers or materials] with beeswax
On a suitable surface that can withstand heat, place down a rectangular sheet of brown paper. Place another rectangular sheet of aluminium foil to match and mate the brown paper, edge for edge. Fold in half to make a square, then open and lay flat once again, with foil facing upward [this it to create a mid line seam as a reference point].
Place the material intended to be treated with beeswax, on one side of the mid line [in the middle of the square]. Evenly distribute a small amount of beeswax shavings over the material and then fold the paper-foil over to sandwich the material. Pass a hot iron [set to medium] over the brown paper to distribute an even layer of melting beeswax over the entire area of the material, which is sandwiched between the brown paper-foil.
Quickly open the brown paper-foil while still hot from ironing, and remove the wax treated material. That's it! You now have beeswax treated material. You can place the waxed material over your kefir jar, and secure it in place with an elastic rubber band, or tie it with string.
It may be wise to seal Stoneware, or non-glazed or glazed terra cotta pots including ceramic crocks with beeswax. This includes certain types of plastic containers intended for use in fermentation. Terra cotta pots may contain amounts of heavy metals due to contaminated clay. This was the case in Mexico, where clay with high levels of lead fashioned into crocks was discovered. Lining the inside surface of crocks or pots with beeswax ensures that the inner surface of the utensil is sealed and safe for brewing. This prevents undesirable compounds from leaching into the kefir, kefirkraut including other ferments of interest.
The pot or containers needs to be heated sufficiently in order to effectively melt beeswax onto the inner surface of the pot or crock or bucket [in the case of plastic]. If the walls are cold, then the beeswax will not penetrate the surface, and shall easily peel away.
Place any terra cotta, stoneware or ceramic pot in a hot oven set to 120°C [230°F] for 20 minutes. Remove the pot from the oven with protective mittens, and then rub a piece of beeswax over the entire inner walls of the pot, including the bottom and sides. Add sufficient amounts of beeswax so that it can penetrate the surface as it melts. Turn the pot around to force an even layer of melted beeswax over the entire surface of the pot as it cools to room temperature. The pot is best turned slowly by hand while it cools down, to ensure an even layer of beeswax is formed and maintained over the surface area as it sets. You should be left with a firm coating of beeswax over the entire inner surface of the utensil.
If the pot is too large to fit in an oven, the inside surface may be heated with an electric hot air-gun, or a hair dryer that produces sufficient heat, while slowly turning the pot until the entire inner surface is sufficiently heated. Once heated, rub a piece of beeswax onto the hot surface of the pot, to form an even layer of melted beeswax, as explained above. A stream of hot air from the hot air-gun or hairdryer may be used to force or guide the melted beeswax over areas where it is needed or lacking. The pot may need to be slowly turned on its side as it cools down, to ensure an even layer of beeswax remains over the surface of the pot as it cools to room temperature to set.
When lining plastic utensils such as buckets, the same process as explained in the above paragraph is used, using a hairdryer only. This is because a hot air-gun may be too hot, which will burn the plastic releasing unwanted chemicals. These chemicals are toxic and shall amalgamate with the beeswax. This [overheating] must be avoided at all cost.
