Coca-Cola sanitizer

I purchased a used 2008 Sierra sport from a RV dealer. The mechanic told me to put a few gallons of water in the fresh tank and then put 10x 2liter bottles of Coco-Cola in the tank also and run all of the fixtures till the water is brown. Let it sit for 24 hrs then drain everything. Has anyone heard of this? I've seen what battery acid does to battery acid. I have no doubt this would kill any bacteria and make the water sweeter rather than like bleach.

I have never heard of that but I wouldn't do it. (Coke? REALLY?) A little bleach kills everything.

I would not do it because of the sugar content.

The bleach would be cheaper.

Can't you use pepsi? I think you should tell him your other leg has bells on, remember coke can dissolve nails.

Never heard of it. Honestly, I would think the sugar in coke would lead to more bacteria. Just use 1 cup bleach to a 40 gallon tank. Run it through. I let it sit overnight but technically speaking bleach really only needs to sit for few minutes to be effective. I then drain the tank, fill it and drain it again. No issues with lingering bleach after that.

DO NOT let this "mechanic" ever touch your unit... EVER. You will have every ant for 7 counties come check you out. Search the forum for the right way to sanitize.

Haha. I was wondering if anyone would chime in. It's a lot of coke. Increased bacteria crossed my mind. And the ant thing finalized the decision. Thanks.

Coke has Carbonic and Phosphoric acids in it and will destroy anything metal it comes in contact with; like your toilet valve and faucets. (Besides the obvious ants and sugary deposits).

10 liters of coke is about 1000 times the cost of a quarter cup of Regular Chlorox Bleach per 15 gallons (3/4 cup per 45 gallons).

If using "concentrated" bleach, use about 1/2 cup.

I use a garden hose and a fresh water fill tip with a shut off valve (I REALLY like the JR Products RV Water Entry Secure Fill 22305 but the much cheaper CAMCO one is also good).

With the water off, pour the bleach carefully into the hose and screw on the camco fresh water adapter and close the valve. Install in the fresh water fill port; turn the water on and open the valve to fill the tank under pressure while mixing the bleach.

Flush the lines with the water pump and burp the city water check valve from the outside until you smell bleach at each valve.

Let sit 72 hours; then drain and fill with city water (with normal amount of chlorine); flush and refill a second time and you are done.
