Food Safe Oil
All my products are sealed with pure linseed (flax) oil. Some linseed flavour may be present for the first few uses of your product. The flavour will fade the more you use the product.
Eventually, after many use/wash cycles your product may need re-oiling. Use food grade oil such as linseed or walnut oil. Simply wipe a thin layer over your product and let it air dry.
Washing
Wash by hand in warm soapy water. Do not soak. Do not put in a dishwasher. Wood is an absorbent material, so new products may pick up stains from colourful foods. Eventually the wood will darken, developing a patina. Your product may also retain some flavours from food or drinks after washing. For example, if you have a wooden cup you use predominately for coffee this might affect the flavour of tea poured into it. Consider using separate cups for different beverages.
Environmental factors
Wood is a living material that will continue to move and change depending on it’s environment. Sudden and extreme changes humidity can shorten the lifespan of your wood product. Do not pour boiling water directly into a cup or bowl that has sat unused for a more than a few days. Prime the vessel by filling it with water and letting it sit for a few minutes.
Some new wooden cups will weep a small amount of liquid from the base. This is normal as the end grain contains pores that, in life, were used to transport liquid sap through the tree. The weeping will stop through use. Letting some fine coffee grounds, or tea leaves, with a small amount of hot (not boiling) water sit in your cup for a couple of hours can help speed up the sealing process. Be aware that this technique will also flavour the cup.
Sometimes wood splits. It’s frustrating but, due to the nature of wood, it happens. If your product develops a crack within the first 30 days of you receiving it, send it back for a full refund.
