I been using original Armorall for ages to clean and condition doors seals. Helps keep them clean and pliable, and it helps keep them from freezing in winter.
This was suggested by Audi 25 years ago...
Funny you mention this,I do the exact same thing,only I use the Armor All Leather Protectant. I use it on all rubber seals (doors,rear hatch,t-tops). 20 year old seals are still showroom fresh
