My latest set of Lee Hard ND Grads are dust magnets. They arrived coated in dust, which was removed using a combination of a rocket blower, luke warm water and a Lee filter cloth, but i've since noticed that they are attracting dust far easier than my other filters (Lee and B+W) when in use or being cleaned. This is particularly noticeable when using the rocket blower, which just relocates the majority of the dust from one side of the filter to the other (unless shielded).

Lee produce a 60ml Anti-Static cleaning solution, is this my best option or is there another method or better product on the market that helps to reduce dust build-up on resin filters ?
