Kill the Suds

What about the liquid they sell along with the rental carpet cleaning machines that is supposed to keep the suds down? It seems like maybe that would work.

I would say just a few slivers of bar soap down the drain. When I was a little kid my mom would make bubble bath for us with dish liquid. As soon as we introduced bar soap to the tub for the required scrubbing, the bubbles disappeared.

We use Dr. Bronners soap instead of dish soap. It is more expensive (you get it at organic-type markets or Trader Joes) but it does not make suds. A few drops will wash the dishes. We also use it for showering, diluted.

I agree - someone is using way to much dish soap...

We use the grey tank chemical. Don't know if it cuts suds but we have never had a problem. Lots of suds is usually caused by super soft water.

Not trying to be a smart%#$* but... less soap. I'd bet everyone in your rig could cut their soap use quantity in half, if not more. For example, I put a squirt of Dawn in a small spray bottle, fill with water and use that to do dishes for several days if not a week. I just spray the dishes, lightly scrub and rinse.
