I've never been to a house where the kitchen countertops are completely cleared off and pristine all the time [At least not a house where the people actually cook and entertain or are humans...]. But when people are looking to buy a house, they don't care about what the kitchen will really look like once they live in it, make a mess of it and actually USE it. They want to see the dream, the idealistic, perfectly in place kitchen.
Yes, if you have seven different electrics and small appliances you use on a daily basis out for all to see, your countertops will seem too cluttered and hint at a lack of storage issue.

Don't have cabinet space for all of them? Keep a nice looking basket with a lid handy to throw them in. It's the little things like this that will drastically improve the look and appeal of your kitchen.
If you're living in the house while selling it, constantly cleaning and decluttering your kitchen will be a pain, but it's an essential for getting the right person to want to take the plunge and make an offer. These staging tips can work for literally any kitchen, no matter how big or small it may be.
