togwt what are your thoughts?

While we are all waiting for Phil to get more Sonax wheel cleaner can you tell us why it changes colors?

i'm guessing something to do with the iron / metal / something in the brake dust.

School us please. :worship2:

 

on the bottle it says it's a reaction to the iron particles

 

Sonax Wheel Cleaner full effect

The best of both worlds; the cleaning power of an acid wheel cleaner with a (safe) pH of 7.5 by using a neutralised acid salt; neutralization is the reaction between an acid and a base (alkaline) producing a salt and neutralized base; common examples include acetic acid and sulphuric acid (hence the red colour, which is a chemical reaction (oxidisation) with the metal particles) forming a miscible emulsion that can be rinsed away and the smell (sulphur) It starts off green, then red and then to blood red, leave it on for a minute, agitate and rinse.

 

Yep must be the iron, because it goes red on the discs almost instantly.

 

Our local version doesnt start off green, its clear

 

Is that an A1 your avatar? Cool.

 

Yes, it is iron, I have confirmed with Sonax.

Yep A1 or Mk 1 same as my wife's car :thumb:

Can you believe they only stopped making them here last year!

 

It actually turns the metal wheel weights yellow, not sure why but the stuff works just smells horrible.

 

I agree with the smell--it is horrible.

I didn't notice a color change on the lead weight though. I'll have to test it.
