Hello, I just have a question. Can you use deionised water which is meant for cars like this:

I don't mind that it's rather expensive because it will only go towards a pico tank so I won't need a lot if it. WC will also be quite small.

The reason I'm asking is because I can't find RO/DI water and buying a unit is out of the question atm.

Would distilled water be better?
 
I'm not sure. The MSDS http://www.farnell.com/datasheets/1854304.pdf
says some scary things. For instance:
ENVIRONMENTAL PRECAUTIONS
The product should not be dumped in nature but collected and delivered according to agreement with the local
authorities.
SPILL CLEAN UP METHODS
For waste disposal, see section 13. When dealing with a spillage, please consult the section relating to suitable
protective measures. Provide ventilation and confine spill. Do not allow runoff to sewer. Absorb spillage with
non-combustible, absorbent material.
 
Oh that is pretty scary! Ok so I definitely won't use it then!!

Thank you again Mr X
 
So just to clear things up, the DI in RO/DI is not the same as deionised?
 
It is, but it's not the same as the link you posted. It can't be. I drink my DI water and the water in that link sounds like something I wouldn't want to drink!
 
Ro/di water wouldn't need a MSDS, it's just pure h2o, so what ever that is there are some chemicals in it.
