Lenses and sensors are such expensive things that I can't see any reason to use bulk products to clean them. I agree with the advice to avoid ammonia, peroxide, etc at all costs. The various sorts of alcohol can work, but as noted, the good kinds are not easily available - and you do not want to use solutions which have been stored for a long time!

Another lenspen devotee here - for the sensor. For lenses, I've used a brush or blower, rarely breath and a very gentle wipe with lens tissue.

I agonized for weeks about cleaning the sensor of my Canon DSLR. It was a *big* job the first time, because I had waited so long before daring to clean the sensor. (I thought I could easily damage the sensor - not so, as has been noted above.) After that first time though, using the Copper Hill method and pecpads, cleaning the sensor has always been easy - not always quick, but always easy.
