I just use normal cleaners - white king etc and cold power, but that water from the wash and kitchen doesn't go through your septic at all - only the toilet water. Normal toilet paper is OK too, but try to avoid flushing tampons down there. If it is set up right, you wont have any trouble with it. We don't do anything special at all with ours and don't have a problem. We have it pumped out every 18mths to 2 years. I don't clean the toilet that often though - clean it with chemicals once a month and use boiling water the rest of the time and it stays clean enough and doesn't smell. Jut do what you would normally do and you should be fine.
