Use a python script. The client data are given in your reddit profile when you create an app.

import praw

reddit = praw.Reddit(client_id='clientid',
client_secret='client secret',
password='password',
user_agent='deletes my comments',
username='username')

redditor = reddit.redditor("username")

for comment in redditor.comments.top(limit=10000):

comment.edit("deleted")
comment.delete()
