All serving boards and anything intended for food service is finished with a food safe mineral oil and a food safe wax. To ensure your thing made from wood stays beautiful and safe, please give a wipe with the same (i.e. food safe mineral oils/waxes). None of my products are dishwasher safe. Wash with warm soapy water.
For tables and coasters etc, just use furniture polish as a regular cleaner and where relevant, an annual wax would help maintain the wood
Please do not store in direct sunlight or keep in exceptionally hot rooms (eg sunrooms/glass conservatories). Use coasters for very hot plates, cup and pans etc, the wood will mark otherwise.
My boards are meant to be serving boards rather than chopping boards. All wood will mark, as will resin, and if you've bought something because it looks nice you may want to avoid carving the Sunday joint on it.
i decided not to screw the lazy susan mechanisms on to the boards as it really is better if they can be removed. Not only is cleaning easier, but you have more options with using the board. Replacement sticky pads can be easily and cheaply purchased - i got the originals on amazon: search for Bostic extra strong glue dots. £2 for lots!
