| 95507 | 2002-11-02 09:33:00 | Hi, can someone tell me please how you clean a CDRW lens and if the standard cleaners you see in DSE etc will clean these. I have been told that you can't use these disks on RW drives by someone but would like this confirmed by some knowledgable person. Thanks Richard |

Then again I can't see how your lens would get so dirty. If you have a lot of dust inside the drive you'd really need to blow it out with compressed air. |

| 95510 | 2002-11-02 22:30:00 | Why do you think the lens is dirty? Anytime I have been asked to clean a CD lens, its never turned out to be a lens problem, its always been that the drive was at or near the end of its life. And to clean, I have always disassembled the unit and used isoproyl alcohol. The lens assembly is delicate, you would use a "brush-type" disk cleaner at your own risk. |

| 95511 | 2002-11-02 22:54:00 | there is special cleaning fluid for cd drives. if you use the wrong stuff it can damage the lens. personally i just take the drive apart and clean it.(and give the pads which clamp on to the cd a cleanup so they grip better) | tweak'e (174) | ||
| 95512 | 2002-11-02 23:40:00 | U guys mean to actually take it out and reach inside the drive?! Will it improve performance a bit, if the drive is pretty old like 2yrs? | vk_dre (195) | ||
| 95513 | 2002-11-02 23:58:00 | take cd rom out ..take cover off, take any other covers/parts off to get access to lazer. use the proper cleaning fluid with the proper cleaning sticks (they don't leave bits behind like cotton buds do) give it a small blast of air and pesto ,,,one clean lens. some cd's have a seperate lens and lazer which can be fun when dust gets between lazer and lens. i live in the countryside so we have a wee problem with dust in pc's. |

| 95514 | 2002-11-03 01:38:00 | "special cleaning liquid" ... yes there is: isopropyl alcohol. Meths is not a good idea. That will make most (transparent) plastics "cloudy". :_| But dust is not likely to be a problem usually ... the sort of "dirt" which will affect the system is gunge which forms a film on the lens ... smoke, traffic fumes, etc. "old age" is the usual problem. Lasers don't last forever. The output power at a constant currrent reduces over time. There is an adjustment, but it's critical. (At least you don't have to worry about the helium leaking [i]through[[/] the glass tube of an HeNe laser) |

| 95516 | 2002-11-03 04:46:00 | > but will it improve performance? Only if you are getting lots of read errors etc . If you have not noticed a performance drop since you bought the drive, lense cleaning will not give you a performance gain . It may or may not in any case depending on the cause for the performance drop . It may be worn motors or circuitry causing problems, not the laser . You still have not said what problem you are experiencing . G P |
