Questions people ask
How is it different from Magma?
Both remove iron contamination. Magma is the smaller consumer product with a 3 to 5 minute dwell; see our Magma page.
Why does it turn purple?
Autoglym says it changes colour as it loosens iron particles [1].
Does it remove tar?
The page describes iron removal only [1].
