What is an easy way to clean kitchen cabinets?

Depends on the type of cabinet. Murphy's oil soap is the safest option.

Murphy's Oil Soap works great. It leaves a nice soft sheen - not oily.

Are they wood, laminate etc?

I have a post that might help https://chascrazycreations.com/cleaning-kitchen-cabinets/

To clean wood cabinets with Murphy's oil soap, you can follow these steps:

1. Dilute the Murphy's oil soap with water according to the instructions on the bottle.
2. Dip a soft cloth or sponge into the solution and wring out the excess liquid.
3. Gently wipe the wood cabinets with the damp cloth, making sure not to oversaturate the wood.
4. Wipe the cabinets again with a clean, damp cloth to remove any soap residue.
5. Dry the cabinets thoroughly with a clean, dry cloth.
