Had to call plumber to snake kitchen sink.

Looked back in check book-- had it done in FEBRUARY! Each time, plumber said it was grease and ? sludge?

That is TOO OFTEN! Never used to need it more than every 3-4 years.

I try very hard NOT to put grease down the sink! I scrape grease into the garbage can before I soak fry pan in soap & water. I hardly use disposal at all; scrape food into compost jar.

Asked plumber what I could put down drain periodically to remedy situation.
He suggested bleach. I asked how much & how dilute, if at all. Didn't get clear answer.

Group, what has been your experience? What do you recommend?

TIA
