+lightning-autoclean-once -- A single deletion of old invoices/payments/forwards
+===============================================================================
+
+SYNOPSIS
+--------
+
+**autoclean-once** *subsystem* *age*
+
+DESCRIPTION
+-----------
+
+The **autoclean-once** RPC command tell the `autoclean` plugin to do a
+single sweep to delete old entries.  This is a manual alternative (or
+addition) to the various `autoclean-...-age` parameters which
+cause autoclean to run once per hour: see lightningd-config(5).
+
+The *subsystem*s currently supported are:
+
+* `failedforwards`: routed payments which did not succeed (`failed` or `local_failed` in listforwards `status`).
+* `succeededforwards`: routed payments which succeeded (`settled` in listforwards `status`).
+* `failedpays`: payment attempts which did not succeed (`failed` in listpays `status`).
+* `succededpays`: payment attempts which succeeded (`complete` in listpays `status`).
+* `expiredinvoices`: invoices which were not paid (and cannot be) (`expired` in listinvoices `status`).
+* `paidinvoices`: invoices which were paid (`paid` in listinvoices `status).
+
+*age* is a non-zero number in seconds.
+
+RETURN VALUE
+------------
+
+[comment]: # (GENERATE-FROM-SCHEMA-START)
+On success, an object containing **autoclean** is returned.  It is an object containing:
+
+- **succeededforwards** (object, optional):
+  - **cleaned** (u64): total number of deletions done this run
+  - **uncleaned** (u64): the total number of entries *not* deleted this run
+- **failedforwards** (object, optional):
+  - **cleaned** (u64): total number of deletions done this run
+  - **uncleaned** (u64): the total number of entries *not* deleted this run
+- **succeededpays** (object, optional):
+  - **cleaned** (u64): total number of deletions done this run
+  - **uncleaned** (u64): the total number of entries *not* deleted this run
+- **failedpays** (object, optional):
+  - **cleaned** (u64): total number of deletions done this run
+  - **uncleaned** (u64): the total number of entries *not* deleted this run
+- **paidinvoices** (object, optional):
+  - **cleaned** (u64): total number of deletions done this run
+  - **uncleaned** (u64): the total number of entries *not* deleted this run
+- **expiredinvoices** (object, optional):
+  - **cleaned** (u64): total number of deletions done this run
