Careful. It is not generally understood outside the engineering fraternity that such fluids can have adverse effects if sprayed about without engineering consideration and approval.
In particular, many fixing items on a structure (eg higher strength nut/washer/bolt assemblies) rely on torque settings to achieve their intended purpose. It can transpire that some of these water dispersants may have an adverse effect on the torque values of a structural fitting with undesirable structural consequences.
Message - if it's not approved in the relevant maintenance documents such use needs to be referred back to the OEM or DERs for approval.
