for places like tops of Fridges, and cabinets that are open up top for displays....
I have seen people use aluminum foil or cling wrap....covering the top of the fridge...and especially wood cabinets...
wood cabinets are not the easiest to clean from grease/dust in a kitchen.....
but with this technique.....just pull off the old grimy ones, and lay down new stuff for Spring cleaning...
you could also probably use shelf liner/contact paper....but may be more expensive to replace over and over...
foam filter used for window air conditioners.....cut to fit the drawers inside of the fridge.....for items like fruits and veggies, keeps them slightly elevated for all around air flow, and helps prevent flat spots...….these you can handwash and reuse...
I have a chrome mixer, toaster, blender on top of my fridge for display.....
I have ropes lights across the top of my cabinets....aluminum foil really help reflect the light....
