Here's one option:

Custom Turntable & Audio Covers

I have my amp on a few hours every day but that means it's powered off most of the time. I put a beautiful old silk scarf over it after the tubes cool down, which means it doesn't need to be dusted nearly as often. It looks good and slightly mysterious. More than once it's given me the chance to show off the amp after someone asks, "What's under the scarf?"

IIRC, Steve Deckert of Decware recommends a 2" (50 mm) soft natural bristle paint brush for his components. That and a Swiffer is what I use, works great.

I use compressed air and cover the equipment with a large silk scarf. I also have one of those acrylic covers made for the turntable. Best of luck 🍀

Swiffer. Maybe I am just lazy. But it works great.
