I have gone back to the Baader Wonder Cleaning Fluid after trying other brands that have turned out not to have performed as well, close, but not good enough.
It does do what it says on the packet - it may take a couple of 'cleans' back to back with stubborn, sticky pollen motes though.
This product does not leave streaks when used with the proper cleaning clothes and swabs.
It seems to be a diluted variant of isopropyl alcohol with high quality demineralised water - a good mix ratio.
I will stay with this product ... Thanks FLO.

Not yet used it. But feel confident it will do a good job.

Usual excellent service from FLO and the cleaning fluid made a really good and easy job of cleaning my SW250PDS mirrors which are 10yrs old and had been lying unused in my shed for last 7yrs so very dusty.

Well worth the money and does a great job of keeping your lenses clean, Best used little and not too often but does a good job of making your lenses crystal clear.

Used this on all my lenses, did a wonderful job. You don’t need to
Use much and you don’t need to do it too often.

Very nice kit which works really well for cleaning my optics!

Excellent cleaning fluid with appropriate cloth. Good value.

Bought this to clean my Sharpstar Z4 lens as it had residue from dew and some dust and pollen from the summer. Followed instructions and worked brilliantly, the objective lens is now really clean. I applied the fluid to the microfiber cloth, not the lens directly. Small amounts initially were not very effective, it was much better with a reasonable amount on the cloth, to really help dissolve and remove the residues on the lens.

Totally brilliant cleaner. Had a horrible grease smear (5 year old grandson learning to use a telescope) on one of my Baader filters. The solution cleaned it off amazingly. Also gave my eyepieces a clean (putting his eye too close) and all of them done with very small amount of spray on the cloth that comes with the set. Seemed a little expensive but worth every penny. Again, delivery from FLO was super fast.

Comprises of spray containing cleaning fluid and soft lint free cloth. Tried on my 12" ODK and cleaned the mirrors a treat! Recommended.
