I always have at least one bottle of this cleaner available at home. It is always the first 'reach for' when cleaning optics. Back in the days of holiday travel overseas, I always had a full bottle in the suitcase in case I needed to seriously clean camera, binos, scope, etc. There are those who say it is a lot of money for 100mL of something you can probably mix yourself. My take is that a bottle lasts a long time. Eyepieces and objectives are expensive items. Why take the risk on your £100 eyepiece or £500 scope to save a few pennies? I have used the cleaner on really filthy glass and it has done the job without resort to scrubbing. I have yet to see any coating issues, or plastic or rubber degrade from overspray, or any other adverse effects from use. When cleaning a newt mirror, I have used the cleaner to reduce surface tension to help disperse the last bit of clean water. It works on general dust, pollen, finger grease, whatever comes off your eyelashes and more.

I am always extremely wary of cleaning Refractor Objective Lenses,but i felt it was needed so i looked around for a cleaning fluid to tackle the job.I had heard about the Baader Fluid and it got good reviews,so i ordered some from FLO.
Carefully i used a Blower to clear the lens from dust etc,and then set about cleaning.Applying a small amount of the fluid to the Baader Wonder Cloth,i gentlely worked in an up and down(not circular)motion.Do not apply the fluid to the lense itself,as their is a danger it could seep down the edge of the lens and into the inner surfaces.The result was very good indeed,and the lens cleaned up amazingly.If you find a few left over streaks due to wiping, just breathe gently onto the lens and carefuly give it a light buff.Job done.
Dont skimp on not buying the Wonder cloth as it has been designed to not scratch the surface as you clean.
A very good product indeed,and i can wholeheartedly recommend this product.

Great service from FLO as usual. Not yet convinced the solution is any better than neat Isopropyl Alcohol but it's certainly easier to dispense. The cloth, however is a work of art. I've tried many different 'lint free' products over the years but this is by far the best. Superb. The supplied instructions are also worth a read. I'd been an advocate of the circular, start at the centre and work out method but the Baader recommended workflow just seems to get better results.

Recommended by Steve Tonkin in his book Binocular Astronomy. I bought the kit including the cloth. I have to say its amazing. Cleaning clear camera protection filters it's so clear so easily that I almost couldn't see that there was glass there afterwards. I easily cleaned some notoriously smudgy polarising filters that I haven't managed to clean before.. One spray from the atomizer onto the cloth cleans a couple of lenses (unless very dirty). In all I cleaned 4 camera lenses (front and back) four camera filters (both sides) two pairs of binoculars, four telescope objectives and seven objective filters. I can't post a picture here but the contents have just reached the top of the squared off section of the bottle - so basically i have used almost nothing. I initially thought it looked expensive but its clearly going to last forever so an amazing buy. Arrived very quickly as always.

yep this is a very good lens cleaner..

I had a mark on the lens of my Zenithstar 70 which concerned me. Although i find the Wonder Set quite expensive my lens is now clean so i am happy with my purchase. There is plenty of the Wonder fluid left for further cleaning when needed.

The cloth with this wonder fluid is magic for cleaning my telescope lenses. Very pleased with the quality, and results I get.
