Combating rust ahd salt buildup in Natures Head Urine bottle.

[Buddhabelly]

Don't know how many of you have heard about "Salt-A-Way" but, this stuff really work good on salt. Anytime when my trailer incounters salt i.e. salted roads, salt air, I wash the underside of my trailer with Salt-a-way. You can purchase a mixer with the solution. Spray the underbody well and you will not have issues with the alunimun frame or axles. Salt-A-Way neutalized salt. Don't have to rinse.  This stuff also work well in removing the salt buildup in natures head urine bottles. I just add some with clean water, let it sit overnight and the salt disolves itself. Rise and you ready to go.

Salt is extremely water soluble, so in my experience, just hosing off your vehicle should remove salt. 

I spent my youth in Chicago where 120,000 TONS of salt are used on the roads every winter. I never got 100,000 miles out of a car before rust doomed it. Salty, slushy water and snow get into crevices that defy washing away. We can try, but it’s a losing battle.

As for the urine bottle on Nature’s Head (or anywhere exposed to urine) any deposit is more likely akin to “stone”. Whether it’s something like “lime” or some other mineral like in hard water I can’t say. Even the rubber seal in the porcelain toilet can get a whitish deposit that can build up on it. I find that plain old distilled white vinegar is extremely effective at removing it. I guess you could use CLR.
