Best way to wipe off the dust cleaning the gear

Swiffer.

The "best" way is to use the brush attachment on your vacuum. Any other way is simply pushing the dust around that isn't being picked up by the cloth or any other method. 

Obviously, you have to be extra careful around tube equipment/table and everything is powered off/unplugged.

Remove the tubes when cleaning!

Really small Roomba.

If one can get sheep to mow a lawn, there's gotta be a way to get the critters in my place to earn their keep.

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.

i always feel that the system sounds much more transparent after monthly cleaning... 😜😜😜

+1 for the Swiffer.

I was thinking about the sheep nonoise mentioned. The aquarium guys use snails to eat the algae off the glass. Then it occurred to me what a wonderful solution! Snails! All we need is a species that eats dust! Genetic engineering to the rescue: The Roomba Swiffer Snail!

The Swiffer Snail already exists.  Small problem though.  Seems to prefer the taste of aluminum cantilevers over dust.  

Another vote for the more conventional Swiffer.

Try cheese cloth as a dusting rag. It won’t push the dust around.

I use a combination of things- you can buy vacuum cleaner attachments that are meant for computer, electronics and the like; from what I understand, vacuum is not supposed to be applied directly to internal components- but used in conjunction w/ a separate brush to catch and remove the debris. I’m not vacuuming the innards but I still use that approach.
There’s a tool called a LensPen that you can find on Amazon or elsewhere as a brand name item. It works pretty well as a dust brush on tubed components - I used it to dust the exposed chassis of a vintage McI MX 110z which is cluttered as hell and has a lot of protrusions set against a chromed chassis.
For anodized sheet metal, I got tipped to Endust for Electronics by the folks at Lamm who I had sent a piece to for work; it came back shiny new and that was what they used.
There is also a pump spray (I’d have to check the brand) that is used to clean computer display screens. I apply that to a very soft cloth to dust the piano lacquer finish on a number of woofer cabinets, and wipe it dry with a similar cloth that is meant for this type of application.
It’s sort of an endless task. My main system is in a dedicated room on the second floor where no one goes but me or my wife- no pets, no foot traffic, yet the dust just accumulates even though we have pretty high grade HVAC, I replace the filters and use a HEPA air cleaner near the cleaning equipment in an adjacent room.

Anything that can be waxed is waxed everything else is cleaned with clean micro fiber rags. They have to be clean.
Wash them with NO SOAP and dry them. I cover EVERYTHING. 
Silk is what I use. WHY?

It does not hold dust
It is mold and water resistant.
It does NOT scratch when removing
When its cut it does not FRAY, that's right it will hold an edge and NOT FRAY. 

I can cut a cover in 5 minutes that drapes, the wife can sew one in 45 minutes that is fitted...

I have silks that are over 100 years old. Beautiful...

1. Wax, all the chrome and paint and nothing will sticks.. Just blow it off with your breath

2. Micro fibers

3. Soft china bristle brushes

4. Soft brush with suction

5. Keep them covered with silks..

I love the snail idea. Good to have a good laugh on such a wonderful Spring day.

There are two extreme personality types, me... don’t sweat the details and well, sweat the details. I’d rather listen and enjoy vs clean.

Swiffer the best way to go by far.

Snails. LOL

My OLD boss use to say "if we could get a broom up his keister, at lest we would get some work out of him..
