ROR Residual Oil Remover - 29.8ml Dropper Bottle. Lens Cleaning Fluid.

A drop or two of this oil remover on a lint free cloth and very gentle wiping and buffing will remove oil and cloudy marks from lens, viewfinders and bodies. Always follow the manufacturers recommendations on expensive equipment. I use it without fear of scratching and smearing, and know it causes no damage. Oil from skin contact, and other contamination is easy to clean off and it is a tiny bottle to travel with.ROR Residual Oil Remover - 29.8ml Dropper Bottle

I encountered this product on-line and was frankly a little sceptical about the claims made for its effectiveness but having read several very favourable independent reviews posted on-line I bought a bottle.Having tried it I can only say WOW! It is everything it’s cracked up to be. I started by dealing with a camera lens which frankly needed a bit of a clean … afterwards the optics were sparkling … so I move onto my other lenses and it was lifting grime off what otherwise appeared to be clean surfaces.It’s not cheap but you don’t need a lot. Apply a drop direct to the surface of the lens / filter and clean with a fresh, fine weave micro fibre cloth. I’m so impressed my camera rucksack now includes a bottle of ROR plus a foil wrapped micro fire cloth (Also sourced at Amazon).I’ve since used it on other optics with similar effects.I recommend this product unreservedly!Mike

Let's face it, lenses are a pain. Proper photographic ones cost a bomb and anyone protecting their investment puts on an ND or UV filter. The problem is that then you end up with a filter that needs cleaning, particularly if you've been near the ocean.ROR is about the only thing you can use. I experimented on an old lens, and although sinful to the photographic community (look away now) started with neat washing-up liquid as it was that oily. It worked, but it was impossible (even under a tap) to then truly clean the washing-up liquid from the lens, I'd swapped one chemical for another. I even tried using a hair dryer to air-dry the lens without touching it, and it still left residue.After research I got some lens cleaning paper (an equally weird almost tissue paper type lint free thing that your gut would say wouldn't work) and ROR. Used the bare minimum as recommended and it completely solved the problem. I should of done it in the first place, but was reluctant to spend 10% of the cost of a filter on the cleaning kit, for cheaper filters the ratio would be higher.Some people say that ROR is just soapy water and I understand where they're coming from in that it has a similar appearance, but from my own experimentation I'd say 100% it's not as it dries streak free and that was impossible with the other option.That said, due to the micro-coatings on a filter (or lens), I wouldn't be cleaning like this every day, but periodically there are things on a filter/lens you just can't shift and for those, there's nothing better than ROR. Keep it to hand with lens paper.

Where possible I just use a lenspen to clean my filters and lenses, but sometimes a wet clean is needed, e.g. for sea spray, rain marks, doggy nose prints etc.Previously I've used Eclipse for this (same thing I use for sensors) but I saw a recommendation for ROR and decided to give it a try.I've found that it can do an excellent job, even better than Eclipse, but there's a technique to getting the best out of it:- Use it very sparingly; one small drop on a pec pad is ample for cleaning even a big front element or both sides of a 77m screw in filter- Have a clean dry pecpad on hand to dry and polish the lens/filter almost immediately after applying the ROR, otherwise you'll be left with a smeary residue that's hard to shift.Used this way ROR is great value (that 30ml bottle should literally last for years) and very effective. But make sure you've got appropriate cloths for applying and polishing off the ROR (e.g. pecpad, high quality microfibre etc)And finally, be aware that ROR is NOT for use on a sensor. Get Eclipse for that!

Cleans the lens immaculately and instantly excellent buy.

I got my ROR(tm) as part of an Opticron cleaning kit.Nightmare stuff to use, just ended up with a smeary mess that took 3 pecpads and several drops of eclipse to almost remove.What the hell is going on with this stuff?One of the reviewers advises using very little and having a dry pecpad ready to clean up immediately. That may be the way to go, but for me it's going in the bin.

it got my camera lenses so clean i think i got two extra stops of light through them

Did the trick, now my smudged lens looks as good as new. As others have said, you need to remove the dissolved oil with a dry cloth as you go, just wiping will simply smear it on and it requires only a minuscule application, I found an ear-bud ideal.
