What can I use to shine up my metal front door?

turtle wax...I used on that on faded garage doors seems be working well

we have used ArmorAll tire cleaner on our doors and shutters. Works wonders to clean ad restore!!

Try some skin so soft bath oil it's also shine's wood tables and wicker.

I would take a photo of the door to the paint department of your local home improvement store and ask them. You may need to repaint and would need guidance on what to buy to get the results you want.

So its just paint. Think of it like a car. Buff the dull off and try wax or maybe some kind of clear coat.

Thank you,I'll try it this weekend.
