Baader optical wonder solution is practically Isopropyl alcohol. Instead of £12 for a 70mL of it, buy a 1000 mL of Isopropyl alcohol for £22 (before pandemic it was only £5). They have also smaller bottles which will be cheaper of course. The Baader solution and Isopropyl alcohol don’t remove the toughest of fungi on optics, only a few of the less deep set ones can be treated with them. I have used both for cleaning eyepieces and on certain stage of cleaning several 8 to 12 inch mirrors. They both worked identical. When applied through an optical cleaning fabric, they remove ( dissolve) fatty oils and fingerprints on optical surfaces. I had cleaned a 12 inch mirror once which for some unknown reason had ice cream stain on it (cleaning followed standard operation procedure for cleaning coated aluminised mirrors).

Isopropyl or isopropanol alcohol is also known as 'rubbing alcohol'. I am very... and would be very cautious... when using it on a glass or mirrored coated surface for optical use. I have used it and occasionally seen a few streaks where it has evaporated before wiping with a surgical/medical grade cotton wool, lens cloth or lens tissue, when removing stubborn stains. I have found when using that the Baader Optical Wonder fluid, a little goes along way, and I finish off with it, if I started my clean with isopropyl/isopropanol alcohol.

Just don't apply to much pressure to the 'pad' when cleaning the optical surfaces, etc., with whatever liquid solution you use.
Interesting to know how the ice-cream🍦stain got there in the first place... :icescream: unless like me... you eat it 24/7...365.25 days of the year! 😋

+1 for the Baader Optical Wonder fluid. It simply works and I know it isn’t gping to harm the lens or objective that needs cleaning.

 

+2 for it. I've had a bottle and the micro fibre cloth for ages and they are still doing a great job.

Not an area that I'm interested in economizing in.

If you wish to opt for cheap and cheerful solutions, then that is entirety up to you. But when there are many people on this site with very expensive refractor scopes worth thousands ,then I do not think spending £12 to use a specially designed high quality fluid  to clean your refractor lens or eyepiece correctly is false economy. And a bottle lasts a considerable time. 👍  for Baader optical fluid

Baader's optical wonder is a solution of 1-propanol and alcohol. Nothing special really. Fantastic marketing though.

Isopropy alcohol is 2-propanol.

Propanol and alcohol are the magic ingredients that protect against fungus in Baader's wonder liquid. They kill spores.

Indeed, the Baader material safety data sheet says it contains 25% ethanol and 35% isopropanol. I presume the 40% rest is water. No mention of anything else like surfactants.

Actually, isopropanol and isopropyl alcohol are 2-propanol. Wonder liquid has 1-propanol, which is more volatile, but really, it is just another solvent.

I once was stupid enough to buy a bottle of Baader's liquid. I was interested in its secret magic ingredients and looked up the data sheet that Jeremy links to. So I found out it's just ethanol and 1-propanol in water. Every active substance must be in the sheet (hospitals use the sheets for toxicology information, manufactures must make this information available).

So Baarder's miracle is that they sell two simple organic solvents in water for over €100 per litre.

The bottle is nice though. But the other day I bought an after-bite spray for mosquito bites. This came in a bottle that makes just as fine a spray as Baader's bottle. It cost €1 complete with after-bite liquid.

So what I did is pour out the after-bite liquid (into a different bottle). I rinsed the bottle and cleaned the nozzle with water several times, then I did the same once with alcohol and refilled the new bottle with 96% alcohol.

Total cost for the spray bottle and 96% alcohol: €2.25.

It's a nice spray bottle with a cap. It won't leak. In it is a fantastic cleaning solution. I can recommend it: It contains a potent  ingredient that protects against fungus.

Very true: I glanced at the MSDS too quickly.

That's pretty rude isn't it ? :sad:

Deliberately posting that in a thread where you know that others have made the choice of the Baader product ?

By all means make difference choices and explain your reasoning but have some respect for other fellow members choices here, as per the forum Code of Conduct. Implying that others are "stupid" is not in keeping with that.

Thanks.

One of the main differences is probably the degree of purity, solvents from cheap sources will probably contain significant levels of impurities which will leave deposits behind on optical surfaces.

I remember back to the days when I used to work in laboratory, 'Analar' (high purity) grade chemicals cost several times as much as the normal grade.

I don't have anything that really needs cleaning, but I must admit to an inbuilt resistance to waste cash on over-priced supremely marketted materials that can be purchased for a fraction of the price by buying generic equivalents (lots of medications come under that hat).  Thus, I would not buy the Baader Wonder fluid on principle as I believe that generic diluted in purified water, isopropyl alcohol would probably serve in exactly the same manner.  

However, just a point about the content of SDS sheets.  An SDS sheet is only OBLIGATED to list any chemical ingredients in a product which are themselves classed as 'hazardous' under EU definitions.  Thus, although it is probably the case that the missing %age content on the Baader wonder fluid IS pure water (that's what I tend to imagine it is myself), it doens't HAVE to be water - it could be any other ingredient not in itself deamed 'hazardous', so it might be an inert non-haz. natural additive, or something like sodium thiosulphate.  So just because there is missing percentage on an SDS sheet it need not be just water.

Didn't we already discuss this in the thread about lens fungus? 

I will say what I said in that thread, in my experience pure Isopropyl is far too volatile resulting in it evaporating before it is able to break down a range of contaminants that you might find on an optical surface.  The Baader fluid is less volatile and I find that it gives you more time to work the surface and hence lift contaminants off the surface onto the cotton pad. 

Sure its more expensive but i see it as you are paying for a little research baader have performed to optimise the mix. Yes one ingredient will be pure water as it helps slow evaporation for example, but I don't feel cheated by that at all.  I have better thing to do with my time than trying save a few pounds by mixing my own cleaning fluid.

@John, I fell for Baader's suggestive advertising and feel stupid for it. Generally I am not stupid and I certainly do not thinks members here are stupid.

I mentioned the liquid before:

and:

and possibly elsewhere too.

So Baader's wonder is an overpriced product that does what it promises. At the same time I feel people should be warned against Baader's suggestive selling point that it contains two anti-fungal ingredients. Any alcohol kills spores.  Baader's wonder is just a mixture of two watered down alcohols: ethanol and propanol. 

I fell for it and wasted some money. I want to help others against doing the same. Like me, they may feel that they are buying a product with special additives that protect against and prevent lens fungus. They aren't.

They are just buying two watered down alcohols for a ridiculous price.

Is it so strange that I felt stupid for doing that?

Just don't imply that other peoples choices are stupid - OK ?

It's not much to ask is it ?

From my perspective I have very little knowledge about what goes into these things, and do not feel motivated to spend time finding out. As others have said, Baader have put something together that works very well and I don’t feel ripped off paying for their efforts.

If you know what you are doing and can source and mix pure components to make the same thing, all power to your elbow. Trouble is a little knowledge is a dangerous thing, and others who know less than you may source the wrong things and run into problems.

100ml of any cleaning fluid really should last years. I don't see how the cost of the wonder stuff is really going to break anyone. I have a large bottle of isopropanol that is older than all of my lenses and eye pieces 😀

Deionised water IS different from distilled, but I cannot imagine either damaging optical equipment.  DI water is often used for steam irons and topping up lead acid batteries and I imagine would be useful on optical equip. or for mixing with IPA https://www.amazon.co.uk/CarPlan-DIW250-De-Ionised-Water/dp/B00FRIH094/ref=sr_1_5?adgrpid=54722411738&dchild=1&gclid=EAIaIQobChMI19Ounpjf6wIVTOd3Ch2w_wUaEAAYASAAEgJk0vD_BwE&hvadid=259088749393&hvdev=c&hvlocphy=9045038&hvnetw=g&hvqmt=e&hvrand=9815806837557291122&hvtargid=kwd-306094015612&hydadcr=28150_1724812&keywords=water+for+irons&qid=1599761568&sr=8-5&tag=googhydr-21

Personally I've never bought the Baader fluid, I use a regular lens cleaning fluid for glasses and it works just fine. Have gone through it quite quickly tho so will need to order some in a few months. Then again I used it on my glasses and have overhauled a fair few pairs of binoculars over the past couple years. I tend to use Zeiss wipes now for my glasses (easier to carry a few in the work bag) or other optics that aren't too in need of a deeper treatment.

      Hi, I have been getting a lot of questions regarding what components my "optical test rig" has, and how to clamp the camera/laser with.

      I found some new bits and pieces which makes it very simple to build your own rig

      Hello all,
      I've bought an old 80ED that had supposedly never been used. It was in its original box etc.
      There's *something* on the lens that looks white-ish. About 2mm by 3mm.
      Looking through from the focusing end it's jet black... Apart from that it looks ok apart from one speck of dust - also black when looking through it.
      What do I do?
      Also, even though the focuser action seems smooth there's a slight 'up/down' to the knob as it's turned. I wonder if it's been dropped and the rod has been slightly bent. 
      So I'm also worried about 'soft' lenses if that's the right terminology.
      How can I check the integrity of the lenses?
      Thanks in advance.
      Context: I had an 8" dob about 5 years ago. Moon. Saturn. Jupiter. Star hopped to the great Hercules cluster. Failed to see Orion Nebula due to light pollution. I'm slowly gathering cheap gear together to hopefully dabble in a bit of astrophotography this winter.

      Hi - I just wanna share my latest build - based on Starlight Express optical rig in which they align their camerachip / housings before the ship them out - And i was inspired to build my own.
      I am very keen to be able to do so much adjustments and tuning to my gear during the day as possible - and this is another method of doing just that, and in this case the aligning of camera tilt which can be a royal PITA during the dark and -20 degree C.

      So, here is the SX article on what i was going to build: SX Article

      Note: I haven't reciieved my new camera yet so the video does not contain the actual adjustment, but as soon as i get my new camera - I will show just how it works!

      Hey Everyone,
      I first made a 6" f/10 telescope back in 2002. It was, as everyone called it here "the minimum size you should make". So I went ahead with it. The f/10 was because some gentleman had ground the glass to f/10 and abandoned it in the local astronomy club and the president of which handed to me.
      After having used the scope until 2009 (I went to UK for my Masters and bought my GOTO setup at the Telescope showroom I was working.  I am primarily an astrophotographer, but one can never forget ones roots can we?
      So, long story short, I am back to grinding a 6' f/8 this time, The FL now stands at 49" (f/8.1). I had finished fine grinding with 1000 grit SiC and moved to 1200 grit SiC but only to realize (after 30mins of grinding) that the seller had incorrectly labelled the powder as 1200 grit. I ended up with large pits all over the mirror and had to resort back to the "actual" 1000 grit SiC. This was yesterday. Now, after about 2 hours of 1000 grit, there are about a dozen pits of varying depth. I think another 30 minutes should get rid of them.
      I tried making a polishing tool from White Portland Cement using the mirror as the mold and aluminum foil as separator. Disaster struck as the cement ate away the foil and got stuck to the mirror in the form of a thin layer (thankfully) and I was able to remove all of it by mild scrubbing and later grinding with 1000 grit SiC. The misadventures that I deliberately get into. 😕
      Hopefully I can start polishing soon. 
      Wish me luck folks. I will post al developments here.

      Hi Everyone,
      I am planning to build a Mirror-O-Matic machine, but since the designer Dennis Rech is not responding to emails anymore, I would be very grateful to anyone who could kindly share the plans of the machines you've built. Anything would be helpful. Images, plans, cur lists, advice etc.
