Rid X

[sheridany]

I want to clean my black tank and I have had a few people tell me to use Rid X mixed in with water full to the top. Let it sit for a week or more and then dump and rinse a few time. Anyone tried Rid X?

I use cascade liquid. Seems to have worked best for me.

Unless you have done something to cause a severe solid build up, I would think that the Calgon or dawn heavy mix with a full tank sitting for 24-48hr would solve the situation. I do this a PM in the black and gray tanks once a year, and then use them without ever doing backwash or other treatments year round.

I keep the gray closed when in use and drain at 80% routinely. Same with black tank, but I suspect everyone treats black that way.

The most harm I have seen is to gray tanks that are left open routinely. Grease and food scum build on walls and smell.

How much Dawn do you use?

I probably use too much, but I have those small dollar general sizes and use the whole thing
