Forgot to clean them first though... Is that a problem? With the layer of grease?

Spray them down with brake cleaner and see if they taste metallic or like the protective coating.

Replaced the rotor, bearings and pads on the passenger side. Easy peasy. But on the driver's side... One of the lug nuts won't come off. Ordered a nut extraction set. Hopefully that'll arrive soon so I'll be able to do the driver's side as well.

I just realized I might have used the wrong grease to pack the bearings. I used ordinary bearing grease with a dropping point of 375F. I'm guessing that's too low. I'm going to get special automotive wheel bearing grease before I start on the driver's side.
If I decide to repack the wheel bearings on the passenger side (and I'm hoping to get some advice if it's really necessary), I'll have to remove the rotor again. I was wondering, will I destroy the inner seal if I do? Will I need to get a new seal? And what's the best way to clean the bearings and remove the old grease?

The grease I always use specifically says 'wheel bearings' on the can or tube, and is rated to 400 F, so you might be fine, what did you use?
I usually use this or Lucas Red 'n Tacky
If you end up re-doing it, a bearing packer and a grease gun would flush out the old grease.

Ball Bearing Grease
Looking up the codes (DIN 51502, KP 2 K-30), the specifications of this grease are:
K: Greases for Bearings
P: EP additive
2: NLGI 2 grade viscosity
K: Highest operating temp 120*C (248*F)
-30: Lowest operating temp -30*C (-22*F)
So yeah, that's not good at all. 😕

Will I ruin the (new) seal if I take the rotor off? There's only one place I found in the Netherlands that has them, and they are between $25 - $30 a piece (including shipping). Same seal, same brand is only $2 in the US... $8 with shipping.

Most likely yes, seal will be damaged in the process.

The same brand has special Wheel Bearing Grease for automative use.
But when I compare the specs of this grease with the grease I used, the only difference is the max operating temperature which is 140*C (284*F) instead of 120*C (248*F). That's not really a huge difference...
