Can you try the canned air that is used to clean keyboards?

Airborne grease and oil from cooking has a nasty habit of settling everywhere.

Test some different spray cleaners (the 409 fantastic type) until you find one that does not damage the finish and works effectively.

Try to vacuum them often with your small brush.

I like the idea of the canned air.. that might work great.. I am going to try it!
I am afraid to damage the cabinets by bringing a vacuum up to it, I would need a smaller more precise one. I have a large on from sears.

Thank you

I take my thinnest microfiber cloth and fold it once. Then I slightly dampen the folded edge with water and then guide it into the crevice. It's worked well so far (5 years.) I don't have to do it very often--maybe once every 2 or 3 months.

ajard,
Just curious, do you find that the upper or lower cabs tend to accumulate more dirt/dust/grime? Or does location of cabs not matter at all?

In our kitchen dust/debris accumulation tends to happen most on lower cabinets--and the lowest parts of those cabinets--the most.

Grease/oils from the stove isn't much of a problem for us. We don't fry a lot and when we do, we try to remember to turn on the vent hood even if odors aren't evident.

zelmar- that's a great idea about using the microfiber cloth.

ajard- we have a small hand-held Hoover and I use a small round natural bristle dusting brush to dust all of our wood and pictures. I have a wide natural bristle for our wood floors.

I use a small, natural bristle paint brush - great for dusting inside corners & grooves & easy on the finish.

1. Assess your venting if you're getting greasy dirt. Maybe you need a higher CFM blower. As others have mentioned, turn on your vent before starting to cook to establish a draft pattern.

2. A high quality 2" angled paint brush is great for dusting--"dust". It gets into the grooves really well. However, if there is grease holding the dust there, it won't work well and you'll need to do #1 and possibly #3.

3. "Damp" dust or clean with a microfiber cloth and a gentle cleaner. NO oil soap or 409 or anything with ammonia. Those can damage the finish over time. Just a microfiber cloth dampened with a small bit of dish detergent if you need to "wash" the cabinets and water only if you're just trying to pick up clingy dust. Be sure to rinse the detergent if you wash them.

It is my lower cabinets that get the grime stuck in the beads.. Upper ones are fine
