You can clean her eyes with a cotton ball soaked with saline solution, the use of a fine tooth comb (or a flea comb) will take all the boogers always easily. As per baths, i used to give weekly baths, now i only give as needed which is always around 15 days. You can make Luna like (and by like i mean accept cuz i think they will never really like it...
) to be cleaned by associating it with something she likes. Exemple, take her for a walk after taking a bath, give her a treat after cleaning her eyes, etc...
