Dawn vs Laundry Detergent

[dcmac214]

Latest Dawn/dish detergent post got DW to thinking (I know, that's a bad thing but I couldn't stop her): Would laundry detergent be better for holding tanks? It's made to cut grease and just about everything else if you can believe the ads; it's low- to no-suds; and volume-wise it's quite a bit cheaper than dish detergent.

Two gallons of water and a cup of Tide laundry soap.
Every time after I do that last dump before the drive home.
No clogs, no smell.
Cheap insurance.

Well, because I have repeatedly succeeded in cleaning level gauge sensors with water AND a small amount of liquid laundry detergent sloshing around while rolling down the road. Water just didn't do the job as well.

Not really sure why you ask why people would want clean tanks, then provide a method for doing so? I had a coworker who got a good deal on a private sale used Travel trailer. The original owner apparently didn't see the need for cleaning the tanks. For some reason the black tank had several inches of hard crusty solids, and the clean out was pretty unpleasant. Given that a half full drywall bucket of water and a shot of clothes soap can leave the tanks looking spotless, if done regularly after dumping, I'm not sure what the issue is.
