when can I put my rabbits in the same cage?

Hello, I did a post a few days ago about my two bonded rabbits that fell out after going the vets to be spayed. I've re introduced them in a neutral area and both rabbits haven't fighted at all. The submissive rabbit is grooming the other rabbit and theres been abit of humping from the dominant rabbit as well. but no chasing, biting or fighting. Seems like them are acting as they use to do. Will it be safe to put them into the same cage now?

How long have they been back together?

Personally I would not put them back in their old hutch if they are not able to be easily supervised for at least a week and only once the hutch has thoroughly been scrubbed with something like a 50% solution of water: vinegar to get rid of the smells of the rabbits.
