What action can you take to prevent accidental data disclosure due to wear leveling on an SSD device before reusing the drive?

Wear leveling is about writing to the disk evenly. Encrypting the data would protect against the disclosure of data on portions of the disk that have remnants due to too much wear and having been set aside as no longer usable. Disk formatting does not effectively remove data from any device. Degaussing is effective only for magnetic media. Physically destroying the drive would not permit reuse.
