johninderby Posted March 1, 2021 Share Posted March 1, 2021 (edited) This is what I use. Not cheap but lasts for years and is the very best. And yes the blower first. https://www.firstlightoptics.com/astronomy-optics-cleaning-protection/baader-optical-wonder-set-cleaning-fluid-and-cloth.html Edited March 1, 2021 by johninderby 2 Link to comment Share on other sites More sharing options...
Second Time Around Posted March 1, 2021 Share Posted March 1, 2021 I start with one of those squeezable puffers to blow away anything loose, then a brush that retracts like a pen, These 2 items are available in kits on Amazon very cheaply. Then I use Zeiss Lens Wipes. They're individually sealed in small packets and so don't dry out. Most importantly though, unlike a cloth, they're always clean. I bought them in a box of 200 off Amazon for a tenner. Link to comment Share on other sites More sharing options...
johninderby Posted March 1, 2021 Share Posted March 1, 2021 (edited) I notice Zeiss has brought out a lens cleaning kit with a microfibre cloth. https://www.amazon.in/Zeiss-16211-Lens-Cleaning-Kit/dp/B00OKK8LV6 Be careful what you use the Zeiss wipes on. They can damage certain coatings although probably OK on most eyepieces., BTW the Baader microfibre cloths are machine washable.

Second Time Around Posted March 1, 2021 Share Posted March 1, 2021 That's the Zeiss kit I have but without the wipes. I had to buy these separately. Link to comment Share on other sites More sharing options...

johninderby Posted March 1, 2021 Share Posted March 1, 2021 So long as they were “fulfilled by Amazon” should be OK. Beware of buying them from marketplace sellers as there are a lot of fake ones around. Link to comment Share on other sites More sharing options...

AstroTim Posted March 1, 2021 Share Posted March 1, 2021 I bought a bottle of Zeiss Lens Cleaning Spray (sold and fulfilled by Amazon so shouldn’t be fake), which states it’s suitable for all optical surfaces, including cameras. However, I have found that it leaves a streaky residue on the binoculars and eyepieces I’ve used it on. In some cases I then had to use another product to remove the streaks. Not sure if it’s due to coated lenses. Works great on spectacles, phone screens etc, without any residue. Maybe the wipes are a different formula. I’ve just bought some Baader Optical fluid and while that leaves some very faint residue marks, these can easily be wiped off with a cloth following a light breath over the surface, if you feel it’s necessary. I’ve only used it on a handful of eyepieces so far but it does seem to do the job, and you only need to use a small amount of the fluid each time, so I’m likely to stick with that for now. I have also used lens brushes to lightly flick off any stubborn bits, that won’t blow off, before using the fluid. However, you need to be careful the bristles don’t get contaminated over time as they can then leave streaks themselves. Link to comment Share on other sites More sharing options...
johninderby Posted March 1, 2021 Share Posted March 1, 2021 I wonder how many don’t realise the Baader cloths are machine washable? Cloth comes out like new after washing. Link to comment Share on other sites More sharing options...
AstroTim Posted March 1, 2021 Share Posted March 1, 2021 (edited) I only used a cloth for the final polish, once all the dirt was off. I used plain Kleenex tissues for applying the fluid. The Baader fluid feels a little sticky when wet so initially I dab the surface rather than wipe in order to pick any dirt straight off the lens. I then use a fresh Kleenex with some more fluid to clean it normally. I use the blower between each stage.

Second Time Around Posted March 1, 2021 Share Posted March 1, 2021 I prefer disposable wipes to a cloth simply because I know they're clean. A cloth could have some dirt on it I miss and that could damage the glass. Link to comment Share on other sites More sharing options...
Bob tries hard Posted March 2, 2021 Author Share Posted March 2, 2021 There is always the possibility of transferring dirt to other surfaces. Wipes seem a good idea! Link to comment Share on other sites More sharing options...
johninderby Posted March 2, 2021 Share Posted March 2, 2021 Never had a single problem using the Baader system and I’ve been using it for many years. No damage, no dirt transfer etc. Just wash the cloth occasionally and keep it in a plastic bag. Link to comment Share on other sites More sharing options...
