Thanks, I still haven’t sealed the wood yet 😅 But I have, since, been looking into something like this instead https://www.thompsonsweatherproofing.co.uk/waterproofing/one-coat-water-seal/ - I also considered a PVA glue mix but I wasn’t sure it was durable enough.

Maybe one of the Asphalt games?

Thank you both, great information. I plan to clean the shelves down over winter, I will try some baking soda, then give them a coat of whatever I have lying around to seal the wood.
