Cleaning stainless water tank
I've dragged out of my shed, an old custom built water tank from my last truck. It sat up behind the rear seats, with cutouts for the wheel arches. Anyway, its sat disused for quite a while now, and I'm putting it back into service. Short of washing out the spiders, what can I do to clean it out?? Its got a very small amount of scale that I can see in it, but was wondering if there is anything I can do to give it a bit of a clean before I take a punt on using it for drinking water...?!
cheers,

chemical I guess, can't get access to clean or inspect. I just don't really know whats in there but it doesn't seem to be too bad, in terms of what washed out. Just a little scale, some cobwebs, that sort of thing.
CLR - isn't that the sort of gear that strips oils stains from concrete? Do I really want to be drinking that...!?

I would use a cap full of HCL, then rinse it out. But thats me. Any acid will clean scale - vinegar etc. To sterilize use sodium metabisulphate - not with the acid it will froth.

1, Hot water
2, Diverwash vc24
3, Hot water
4, Diversheen 5
5, Hot water
obviously hot water rinses, vc24 is a light slightly basic detergent and divosheen 5 is an acid sanitizer for killing bugs - available from johnsondiversey.
or just give it a good hot soapy rinse (flushing out all traces of soap) and use some baby bottle sanitizer.
And after all that give it a squirt of ethanol - will kill bugs and taste good too (bottle of smirnoff should do)

did a run with bi carb soda, didn't see much come out which mean a) its pretty clean, or B) its in need of some more horsepower.
I think I'll just run water through it a few times before we start drinking from it... Not sure I want to run the risk of being eaten from the inside out...?! I'd love to run the steamer in there, but can't get access through the top of the tank. Now just need a little low power pump to get the water to the rear tailgate on a momentary switch - pond supplies you reckon??

That's "pickling paste" It's basically nitric and sulphuric acid in a gel base so it stays put.flylux wrote:I was helping a guy fit some stainless steel handrails at work the other day and he would use this liquid stuff to clean the welds off after welding it. He wore chemical gloves because he said if it gets in a cut in your hand it will eat your bone away!!!
Yes very nasty stuff. But cleans stainless welds up so well. As well as the aesthetics of it, it eats out any unprotected steel and stops the weld area from rusting.

In the food industry, we have to specify (yep, i'm a draftee) all food contact welds to be cleaned and passivated, the workshop uses the pickling paste as per above, plus other stuff i think... Not too sure, I don't spend enough time down in the shop.

Yea i'm in the food industry also (which is why i said about the diverwash/diversheen combo which is something we use (with micro swabs to back up effectiveness) to automatically CIP wash - basically flush without mechanically scrubbing for products like caramel, batter, chocolate.) for most other manual cleaning we'd use 70% ethanol in a spray bottle - 70% was shown as the ideal ratio in which the ethanol can break through the cell wall of the microorganism.RO8M wrote:This. ^^KiwiBacon wrote:That's "pickling paste" It's basically nitric and sulphuric acid in a gel base so it stays put.flylux wrote:I was helping a guy fit some stainless steel handrails at work the other day and he would use this liquid stuff to clean the welds off after welding it.

As far as food welds go you're right but all the backs of the welds would ideally be purged with argon (if you welded a s/s tube for instance)
And then after it was all pickled, that nasty stuff would be well and truly rinsed off and the assy would be given a squirt with ethanol.
As far as the water tank goes id use ht soapy water (dishwashing liquid) flush all remaining soap residue then hit it with some baby bottle or home brew sanitizer - shouldn't be too bad if its only had water in it though.
