$/ is the The input record separator, newline by default (see the perlop man page; type perldoc perlop and find it).
The code you posted could be re-written like this:
foreach my $key (sort keys %clean_data) {
print $key, $/;
foreach my $data (@{$clean_data{$key}}) {
# the hash value $clean_data{$key} is an array reference
# wrapping it in @{} gives us the array it references.
# this array contains array references,
# so @$data gives us an array
print "\t", @$data, $/;
}
}
