I pretty much use the TeleVue system to clean eyepieces though for eyepieces with large eye lenses, I sometimes use surgical cotton balls..

For a fluid, I tend to use either 91% Isopropyl or pure ethanol which my friend Bob buys for me in Mexico.

Regarding removing grease..

One night I wanted to clean my 9mm Type 6 so I grabbed the canned air to blow off the dust.. It took me but a second or two of spraying to realize it wasn't the canned air I had but rather a can of spray grease..

That was not a good thing..

It was touch and go for about 30 minutes there but between the ethanol and some GOO GONE, I was able to clean the eye piece..

These days, the spray grease in the garage, not in the scope room..

I blow the dust with a bulb first.
I use ROR, but the first swipe if the lens is real greasy, there will be a smudge.
It pulls the grease out of out of the scratches in the glass.
I first apply ROR to a micro fiber cleaning cloth from the orion website.
Then I dry it, with the dry part of the clothe.
I also use the zeiss wipes from walmart and sams club, then dry it with orion micro fiber clothe.
Never had a problem, coatings are very hard. Now with a plastic lens, i just try to blow of the dust or a dry swipe.

Do you take out the worm?

I have a license to purchase ethanol from the state of Virginia, but I read recently that they were going to start selling Everclear in the state owned liquor stores.

I don't like homebrew stuff several recommended me here in Sweden.
I'm not keen either use acetone.
Alcohol sounds better. Is that ROR ?
I might try get that here.

I has this kit ;https://www.bhphotov...aning_kit.html#!

I don't know what is in this cleaner spray. Do anyone know ?
There is also wet pads in kit, equal as 'kimwipes' ?

-Is it wrong clean off whit cotton ?
What I found out a issue is if I spray on a cotton ball and get it on lense ( not rotate, just up/down )
But when I try to remove it will be a mess hard to remove 'dry'.
But if I breathe on lense I need only some turns whit a cotton ball - then it is clean.
But one above mention on a article say never breath as spit ( can come.
But that’s the only way remove this spray.

It do works, I get it clean but I like clean stuff and if I often clean - I don't want to destroy my stuff.

I don't think this spray from Zeiss will hurt lense, I'm worry on my cotton polishing.

The fluid in that kit is a mix of water and alcohol.
Kimwipes work well.
Cotton balls can leave lint on a lens and often are treated with skin conditioners. Better to use pure cotton "Q-Tips"
If a residue is left on a lens, pure distilled water and a Q-Tip can usually remove it.
Zeiss and Nikon both make decent lens cleaning fluids.
ROR is gentle and removes all organic oils and grease very easily.
It's water, alcohol, ammonia, soap, and salt in a mix just right to be an effective cleaner.
The original Windex with Ammonia also cleans eyepieces well that are not too dirty.

This is what I describe what one at Stellafane use.
He took his Ethos out of a box and polished direct on lense.
Just breath off dust and worked out whit this pen.
He said, don’t worry. Coatings is hard.

That tool is hard enough to scratch, leaves a residue of powder on the lens, and is only clean the first time it's used. After that, it is spreading dirt and oil around.
You should NEVER use one on an eyepiece. Ever.

Personally I only use distilled water on soft paper handkerchief, or on cotton swab, it removes all traces of grease and dust, but I'll try Purosol one day.
