Sensor Clean Solution from VisibleDust has many characteristics that make it an excellent choice for cleaning your digital camera sensor. This unique cleaning solution leaves no residue or film because it is non-alcoholic and non-hygroscopic; plus it is also non-flammable, non-toxic and non-corrosive to the sensor. While Sensor Clean is best used to remove water based stains and light dust contamination, it also provides excellent dust repellent properties and anti-fogging capabilities. Sensor Clean works best when applied with VisibleDust Green Series Swabs.
