We call this “article washing” for a really good reason. Namely, the A key was taken, so we had to use the W key instead.
Washing is defined by us as “changing something from something to something else”, but normally results in something looking better. Cleaner, perhaps.
See Customizing Articles, if you want to change how Gnus displays articles by default.

really washing. If you type this, you see the article without
any previously applied interactive Washing functions but with
all default treatments (see Customizing
Articles).gnus-summary-stop-page-breaking). See Misc Article, for page
delimiters.gnus-summary-caesar-message). Unreadable
articles that tell you to read them with Caesar rotate or
rot13. (Typically offensive jokes and such.)
It's commonly called “rot13” because each
letter is rotated 13 positions in the alphabet, e. g.
‘B’
(letter #2) -> ‘O’ (letter #15). It is sometimes
referred to as “Caesar rotate” because Caesar is
rumored to have employed this form of, uh, somewhat weak
encryption.

(gnus-article-treat-dumbquotes). Note that this
function guesses whether a character is a sm*rtq**t* or not,
so it should only be used interactively.
Sm*rtq**t*s are M****s***'s unilateral extension to the
character map in an attempt to provide more quoting
characters. If you see something like \222 or
\264 where you're expecting some kind of
apostrophe or quotation mark, then try this wash.

useful if you're on a terminal that has a limited font and
does't show accented characters, “advanced”

Quoted-Printable is one common MIME encoding
employed when sending non-ASCII (i.e.,
8-bit) articles. It typically makes strings like
‘déjà
vu’ look like ‘d=E9j=E0 vu’, which doesn't look
very readable to me. Note that this is usually done
automatically by Gnus if the message in question has a
Content-Transfer-Encoding header that says that
this encoding has been done. If a prefix is given, a charset
will be asked for.gnus-article-de-base64-unreadable). Base64
is one common MIME encoding employed when
sending non-ASCII (i.e., 8-bit) articles.
Note that this is usually done automatically by Gnus if the
message in question has a
Content-Transfer-Encoding header that says that
this encoding has been done. If a prefix is given, a charset
will be asked for.gnus-article-decode-HZ). HZ (or HZP) is one
common encoding employed when sending Chinese articles. It
typically makes strings look like ‘~{<:Ky2;S{#,NpJ)l6HK!#~}’.gnus-article-treat-ansi-sequences).
ANSI sequences are used in some Chinese
hierarchies for highlighting.gnus-article-unsplit-urls).gnus-article-wash-html). Note that this is
usually done automatically by Gnus if the message in question
has a Content-Type header that says that the
message is HTML.
If a prefix is given, a charset will be asked for. If it
is a number, the charset defined in
gnus-summary-show-article-charset-alist (see
Paging
the Article) will be used.
The default is to use the function specified by
mm-text-html-renderer (see
Display Customization) to convert the
HTML. Pre-defined functions you can use
include:

Buttons.gnus-article-add-buttons-to-head).gnus-article-verify-x-pgp-sig). Control messages
such as newgroup and checkgroups are
usually signed by the hierarchy maintainer. You need to add the
PGP public key of the maintainer to your
keyring to verify the message.1gnus-summary-force-verify-and-decrypt). See
