Quick answer
Once a year Aaron made atonement on the altar's horns with blood, marking it most holy. Even the place of prayer needed yearly cleansing by blood.
Overview
On the Day of Atonement the incense altar itself was purified with sacrificial blood, showing that nothing in worship is free from the taint of sin. This annual, repeated atonement revealed the limits of the old covenant system. It points to Christ, whose once-for-all blood cleanses both worshiper and worship perfectly and forever (Hebrews 9:12).
