I make sure I clean the brush on the lens before and after use with another fine brush. One should give the lens cleaner a good visual inspection and also gently nudge the brush at the base (with another brush, not with fingers) to make sure it is not coming loose. Since 1946 Onkyo has been passionately committed to developing audio products that deliver preeminent performance, quality and value. In March 2015, Onkyo purchased Pioneer Corporation's 'Home Electronics Corporation', which makes home cinema amplifiers, Blu-ray players and other AV products. And casual users will normally blindly believe these products than use some knowledge and judgement. The word Onkyo translates as 'sound harmony'. Or might come off while spinning and damage the lens. Placing a CD inside while not in use is one option, but it does not prevent dust particles suspended in air gradually settling on the lens.Įven the recommended engineers would have to use some tool - I guess it would be a fine brush or a cotton bud as pressurised air canister would further push dust particles in and a vacuum would be risky.Īnother reason manufacturers would not like us to use CD lens cleaner is that the brush might be loose - the side it sticks to the CD is set hard by the adhesive - causing abrasion. However, dust will accumulate as air is drawn in by the spinning motion as well as fine dust particles collecting during rest. However, if you are cleaning every week or month, that wear can accumulate very quickly.Ĭommon sense and moderation in all things.ĭust on lens should not degrade sound quality.Unfortunately for me (and many like me) my CDP drive mechanism is not sealed ( link), though NAD have been clever enough not to provide any vents on top of the CDP.
So, the use of a lens cleaner every couple years is probably not going to do much to damage the equipment. So, not that much dust is accumulating inside the player on the assumption the disks themselves are clean. I suspect you can find people here who have had the same CD or DVD player for 10 years or more and have never cleaned it, and it still works fine. Let's consider how often you need to use the lens cleaner?
So, what they really want is for you to not use the lens cleaner within the warranty period. Then you would want to collect on the warranty. You could use a good lens cleaner or you could use a lens clearer roughly as abrasive as sandpaper. It represents something they can't control. I suspect that most CD maker recommend you don't use a disk type lens cleaner. Slightly off the topic, but I bought an Epson printer years ago, that said if I didn't use Epson paper I risked damaging the printer.
