There is a additional use of the VSGO sensor cleaning kit. It will sit idle for a while after a successful sensor clean, so I put it to a alternative use.
I have used it on my lenses front and rear elements. A good blow from the air blower first, followed by One drip from the bottle on the front glass element,
then smear the solution around the element with the spatula, and a wipe dry using a absorbing lens paper wipe, this will leave the glass very clean.
For the rear lens element put a couple of drops of solution on the spatula, then carry out the previous steps.
I used one spatula on five lens, and felt comfortable with this.
As a last job after the element cleaning was done to the five lenses, I chose to extract the most from a spatula, I also gave the front and rear plastic protection caps a good blow internal/external faces, and then removed any stubborn remnants with the wet spatula before discarding.
