This is {{Cleanup|reason = reason for cleanup|date = month/year (e.g. January 2011)}}.

For example {{Cleanup|reason = the article is full of incorrect capitalisation|date = January 2011}} - would display as:

Place this template at the top of the page or section needing clean up.

If suitable, use a more specific clean up template. Because this tag is general, identify the specific problems in the reason field - detail can be provided on the page's talk page. The template might be removed without the problem being fixed if it is not possible to identify what needs to be cleaned up.

The template detects which namespace it is used in and changes accordingly:
Article
Category
Template

The descriptor (on the preceding example "template") can be changed from its default using the first parameter, for instance {{Cleanup|section}} or {{Cleanup|disambiguation page}}.

Add a new section to the talk page explaining the type and extent of clean-up required so editors will know what to address, and when to remove this template.

This template is a self-reference.

Do not substitute this template.

Use this tag when the article needs improvement per WP:BETTER. Articles that violate policy need more direct action.

This template will pages on which it is used to a specific category containing pages needing cleanup or a dated subcategory thereof.

If the problem is correctable with the skills you already possess, consider being bold and fixing it yourself, rather than applying this template and leaving it for someone else to clean up.
