Not all debt has the same rate

Technical debt is not a moral category. Some debt is cheap and intentional. Some debt charges interest every time the team ships, reviews, debugs, or onboards.

Make cost visible

Describe debt with the cost of delay. That makes prioritization possible because product, engineering, and operations can compare the same thing.

Choose the paydown moment

The best moment is often just before debt becomes a coordination tax. Pay it down when you are already touching the boundary and can prove the improvement.
