How to clean painted metal doors?

Question

when I use just a water, it does not get clean because there is a greasy spots (darks, black, gray, etc); if I use cleaner like Spray9, Simple Green, etc), the paint comes off gradually after each cleaning, more and more.

Thank you

Answer 1

I agree once you get it cleaned you need to repaint with an oil based paint. Try using either 409 or Multi-purpose spray cleaner by pledge. They both work pretty good.

Answer 2

Use  409  it  works  great  it  will  make  the  metals  door  clean ,  it  removes  grease  and  other  stuff.  It  won't  take  the  paint  off.  I  use  it  on  everything.

Answer 3

The paint sounds like the problem, not the cleaners.  It sounds like they have a chalky coat of latex.

I'd sand lightly, and then put down an oil-based primer, then an oil-based coat of enamel paint.  After this, the paint won't come off when you clean.  At all.

Answer 4

TSP (tri sodium phosphete) you can get in the paint dept. It is made specifiacly to safely remove grease and grime from painted surfaces without harming the finish
