Low standoff components, flux removal

Is there any field proven spray cleaning technique able to remove flux residues under OSRAM LEDs? Is it possible in principle?

The problem is that OSRAM LEDs are low standoff ones and I absolutely have no idea how cleaning agent could get there.

More process details:

Cleaning machine - spray (clean, rinse, dry) Cleaning agent - Vigon A250 Paste used - KOKI S3X58-A230 OSRAM partnumer - LRTB GRTG

Any input would be really appreciated.

Regards, Pavel
