How can I keep copper door handles clean?
Our house is 23 yrs old the outside door handles are really a mess. I’ve tried different things to clean but nothing worked so I sprinkled bartenders powder on a wet sponge the added enough water to melt the powder. I then cleaned the patio door knob and it looks great . Then I started to clean the front door handle, not so good. You can see the pic I’m sending it doesn’t look good at all so stopped immediately. Is there a way to protect what I was able to clean.
