This kit by Visible Dust includes the VDust Plus cleaning fluid (1.15ml), DHAP orange 1.0x (24mm) sensor cleaning swabs and a SwabLight. If you are unsure as to the nature of your stain or you get both water and lubricant stains, VDust Plus will fit the bill perfectly. Designed to clean away water and most oil stains, VDust Plus eliminates streaking and provides a moderate static barrier. The swabs (4 included), with their unique fabric folding system, are specially tailored for cleaning your delicate sensor without leaving streaks, pooling or abrasions. The SwabLight attaches to your swab and provides a clearer, brighter view and a better grip. It runs on 3 LR44 batteries (included).
