Any ideas why you can only use the Mothers on aluminium?
Ahh, re-read the destructions again and it suggests that it can be used on metals other than Alu, but you need to test the metal to see.
1. Apply a small amount of polish to a terry cloth towel.
2. Rub polish onto metal surface until black residue appears.
3. Buff off residue with a clean terry cloth or microfibre towel prior to polish drying.
4. Hard rubbing is not necessary. Use sparingly.
Note: If black residue does not appear. STOP, it is not a polishable metal.
No matter how bad it gets... it could always be worse.
