Description
  • 100ml Optical Wonder™ Cleaning Fluid, dislodges dirt, aggressive aetherical oils from pollen and fat
  • Dries up completely without leaving any residue or wipemarks

  • Works on all sensitive optical surfaces
  • Forms an invisible protective layer against bacteria and fungi which tend to eat glass and coatings

Baader Planetarium's Optical Wonder Fluid is the finest lens cleaner we have found. It does a consistent job of cleaning oils and organic contaminants from stubborn multicoatings while leaving almost no residue. Beyond being a superb cleaner, Wonder Fluid also includes unique properties. Ingredients within Wonder Fluid are designed to prevent growth of the types of fungus that have been proven to damage (literally eat) lens coatings. We've seen first-hand the results of this type of coating damage on costly APO refractors, and welcome the added measure of protection Wonder Fluid gives.

We use Wonder Fluid for the majority of our cleaning needs in our business and in the field, for eyepieces, prisms, refractor objectives and dielectric mirrors (Note: Cleaning of traditionally coated mirrors requires a much different process and uses common water and detergent - not lens cleaners and cloths). We have found Wonder Fluid to be the best general lens cleaning solution for our purposes. It is extremely lo-residue, and cleans quickly without the excessive fussing some cleaners require, and we really appreciate the antibacterial properties.

Baader's Optical Wonder Cloth compliments Wonder Fluid. Baader's cloth is made from a finer grade microfiber than the typical lens cloths sold at camera stores or eyeglass stores. When paired with Wonder Fluid, it is easy to keep lens surfaces clean and working like new.

Our Own Thoughts on Cleaning: Cleaning optics seems to be one of the banes of this hobby. Everyone has to learn their own way on this subject, including finding their favorite lens cleaning potion. Over the years we've tried most of the available lens cleaners, including some touted by friends or manufacturers as the best or residue-free, and found that most fall short. Very few have come close enough for our own 'picky' tastes (some highly regarded and expensive 'high tech' cleaners have turned out to be real duds). We try to keep our optics as close to new as possible - clean and free of visible residues or discolorations, even under bright light at varying angles. Modern multicoatings are brutal in their ability to show the presence of tiny amounts of contaminants.

In the end, we have only found one solution that produces completely residue-free cleaning - photometric grade acetone or alcohol. Using these ultra-pure solvents takes care and practice to achieve a pristine surface that is completely free of the faintest discolorations. The effects of these discolorations are negligible in use, so we recommend avoiding over-cleaning in an attempt to eliminate every trace. In general, we recommend most amateurs stick to less aggressive cleaners, particularly since there is now an excellent alternative - Wonder Fluid.

We also highly recommend the use of our Rocket Air Blaster to initially remove debris and fine particles from optics, prior to the application of fluid and cloth.
