If I open my PCR tube in a PCR cabinet with outside filtered air pushing through, any aerosol will be pushed away by air flow. Any possible remaining amplicon can be degraded by UV light or cleaned chemically and cabinet will be free from any amplicon. The question is what evidence you have or you can refer to show that usual lab hygiene is not sufficient to prevent PCR contamination. An amplicon that supposedly sticks to lab wall, how likely can be airborne again and land in a PCR tube. In a very slim probability if it lands how that really is going to affect results because the target amplicons will be in billions.
I strongly, would suggest external expert review of ancient DNA set up and practices if they can not control PCR contamination.
