Generic Unbranded Unthickened Bleach

Aluminium flake is quite commonly used to protect steel from corrosion, not as effective as zinc powder and definitely not as effective as galvanising. Silberline (owned by Altana) are one of the biggest players in aluminium pigments. if you are using aluminium flake as a pigment in a paint you really need a decent resin system or the aluminium will simply be 'washed' off.

As I said, I used sunflower oil. Im afraid it didnt wash off, though I suppose if it had been sukected to pressure washing, say by typhoomal rain, before it had polymerised it might have. This was in Taiwan so polymerisation would be significantly quicker than in the UK, and the oil was old so probably already partially polymerised.

Cocs Cola are one of the biggest players supplying my aluminium pigments, but it baries by location

I second Ylop, all you need is a pure sodium hypochlorite based solution as used for babies bottles eg Milton. It will do the job of sterilising your water tank.

I haven't read all the replies but what you need is sodium hypochlorite. It's potent stuff and will eat through your clothes when neat. It's not too bad if you get it on your skin if you wash it off right away. Definitely nowhere near your eyes.
We used to use it when we had our dairy herd. There must be farm supply outlets in the rural parts of Taiwan, I would imagine that they would have it.
It does need a lot of dilution though. It is corrosive if used unwisely.

Thanks. Im no longer in Taiwan. Such things tend to be more available there though can be difficult to find without Chinese

I'd take a quick survey of your local supermarkets and simply buy the cheapest, sodium hypo you can find - its probably generic, no additives. As soon as they make additives the price will go up. I'm guessing the supermarkets or their suppliers deliver in 1,000l containers and the cheap stuff on the shelves is simply repacked in 2l container for retail.

Your ideas are interesting (and do not merit the sarcasm nor scorn). Using the report button might be useful to quell their comments. To me you are maintaining the spirit of PBO. Report back when you have some firm results.

I'd do the same with your choice of vegetable oil- use the cheapest first and olive oil last )
