The Manufacturers In-House Methods

Only Kodak, Leica and Fuji support the consumer in using the same method 
that they themselves use for cleaning the low pass filter. All the 
others manufacturers only support the non-physical contact use of a hand 
blower. If Canon, Nikon, Olympus, Pentax or Sigma, can tell that you 
have touched the low pass filter, your warranty is void. On the other 
hand, Photographic Solutions Inc., guarantees that you won't damage your 
camera, if you use their Sensor Swabs™ and Eclipse™.

     * Canon - Blower and a Kimwipe, held by tweezers. They do not like 
to use fluid but when necessary they use either 90% isopropyl alcohol or 
a 50/50 mixture of isopropyl alcohol and Windex.
     * Fuji - Photographic Solutions Sensor Swabs™ and Eclipse™
     * Kodak - Photographic Solutions Sensor Swabs™ and Eclipse™
     * Leica - Photographic Solutions Sensor Swabs™ and Eclipse™
     * Nikon - A commercial grade lens tissue wrapped around a chopstick 
style piece of wood with medical grade methanol. Several forums have 
posts where readers have been to Nikon Service outside the USA and 
reported seeing the technicians using Sensors Swabs and Eclipse.
     * Olympus - A Kimwipe held by tweezers and Olympus Proprietary 
Solution (dries quickly without streaks and is bio-degradable).
     * Pentax - A special lint free cloth (provided from Japan) folded 
into a small square and held with a pair of tweezers as a swab moistened 
with a freon derivative.
     * Sigma - Uses a special vacuum cleaner that was provided by Japan.
     * Sony - Uses Sensor Swabs™ and Eclipse™ by Photographic Solutions.
