I use the eyelead gel stick - very effective and no fluids involved.
Guessing it doesnt work with anything besides dust?
Just read some reviews on amazon and a bit mixed, 44 @ 5 * and 9 1* with some horror stories

Don`t need any cleaner yet but think I might wait a bit, guess it could be user error or as one review suspects the gel may be temp sensitive.
For me 9 bad against 44 excellent is not a good ratio on Amazon
