With proper care, quality wood bowls are meant to last a lifetime. However if you're dealing with an well-used bowl that has plenty of build up, staining, and possibly a rancid smell, simply follow these steps to restore it:
1. Build up is usually from vegetable based oils, which leads to bacteria growth and the bowl feels tacky or sticky. Using a non-abrasive scrub pad, apply lemon juice to the bowl and build up to remove the old layers of oil.
2. Sometimes it takes more than one go-over with the scrubber and lemon juice to completely remove the layers. Once removed, wash in warm sudsy water and towel dry well.
3. Generously apply a food safe, mineral oil to the bowl. Let it sit for 24 hours. Once dry, your bowl is ready to use!
Be sure to always use a bowl and board rub that is non-vegetable based to avoid future buildup.
