Deleting a custom field value

Hello Community,

I am adding a value to one custom field. Since, this value occupies big disk space, we want this value to be deleted two days later. Kindly help with the logic as I am new to RT.

P.S:
We wish to keep this custom field value for two days. Then either delete these custom field values or replace it with empty values.

We already went through below link, but it has some limitations. It requires a specific custom field value to be entered. But we are focusing on all the values. Basically custom field value = *
