Does anyone know of a reliable method of cleaning wildflowers

Dunno about reliable, but many bugs leave the flowers pretty soon after you have cut them.
You could also try slaughtering your new pets with heat or poisons, but their dead bodies would still remain.

Freezing them in a vacuum chamber?

It ought to kill everything while leaving the plant pristine

Quick rinse with water is the easiest or dunking them in a small container of water.

If you gather them for drying note, that bugs tend to leave drying grass and flowers. P. S. For the plant shown in picture, you should use it's roots for remedies. Sadly can't remember from what it is...

Quality spray bottle. 2 cups warm water, 2 tablespoons dawn. Mist them. Can wipe down after or not - won't hurt the plant, will kill all pests.
