can you dip rusty keys in this to remove rust?

use vinegar, just as effective and probably in the cupboardkind regards pauline

Does the 90ml pot have a brush attached to the lid?

You wouldn't want a brush attached to the lid anyway as it's important not to contaminate the liquid in the bottle with rust particles as it'll cause the chemical to activate in the bottle. Always pour a small amount into a container and work from that. Don't poor left over liquid back into the bottle as that will also contaminate it.

What colour does it dry ?

Black with a "blueish tone" Ok left as is but would look better with a coat of Hammerite Smooth Black or Dark green.

can this be used on a BBQ

Once dry, this needs to be painted over. I don't know of a paint that will withstand BBQ temperatures and the constant scraping required. I would remove the rust with a wire brush then coat it with an edible oil. Clean it immediately after use and re-coat with oil to prevent rust forming. Best of luck!
