I polished up the OG109 Friday. Had her looking mighty spiffy! We are going on our 2nd nasty, damp day here and I started noticing a bunch of rust on the surface. I wiped it down with my finger and it came right off. Just a light dusting of rust, but a kick it the nads for all that hard work. Now I see why people opt to paint their stoves, although that polished cast iron is oh so sweet! Amazing how fast they get surface rust on them. What's funny is the Chubby sitting 2 feet away is clean as a whistle. Once the stove is lit (soon) it should drive away the humidity.

Dude,.... you live on an Island. It's only slightly dryer on LI than having a screen door on a submarine ! :D

Seriously though, I've found that it can take a few times coating with polish and buffing it out to fill in and protect cast iron against rust.

And, there are different types of rust - active and inactive. If the polish is put on over active, light red rust it will continue to rust. Before polishing, I wire brush any red rusty areas down to the " dark, inactive rust". We've just gone through one of the wettest summers in the 25 years since I moved here from LI. Well polished areas of both stoves have not shown rusting through the polish (Meeco brand).

I like to spray the stove with cooking oil(pam) mostly in the seams..not as good as polish but quick and easy ...............wilson

Wilson,
I tried the cooking spray way back after you showed it to me. I agree that it does work well for preventing rust,.....

...... but it's bad for a diet ! :oops:

Every time the stove heated up the veg oil, it smelled like frying food and I'd get hungry ! :D

I read somewhere on this forum to apply viniger before wire brushing. I tried that this year. Sprayed it on and let it sit for awhile. Actually I forgot it for a few days , well when I returned what a mess. Rust all over as the vineger dried . I reset it with more vineger and wire brushed right off. Then gave it a good coat of polish and it turned out great! I agree the polish really makes it look better than paint.

White vinegar is an inexpensive rust remover. But, with a PH level in the low 2's (out of 1 to 14) it's a fairly strong acid and it has a lot of water in it, So as you found out, if left on to dry it causes more rust and leaves a higher concentration of acid behind as the water evaporates away.

After using any acid to clean rust, even if you dry it off before it dries out, the surfaces should be neutralized or the acetic acid in the vinegar will remain in the joints of the stove and the pores of the cast iron. That trace acidity might affect the polish.

The surfaces should be rinsed with a solution of baking soda in warm water and then dried.

If using a water based stove polish like Williams or Meeco you can polish immediately after.

Thanks for the tip Paul . If the rust shows up again I will redo and rinse with baking soda before applying the polish.

Two choices. Run the stove 12 months of the year or do what I do put a 200w tractor sump heater in every working stove for the inactive months. I am to lazy to grovel around with spraying/painting anything.

Yes logs, I am imagining I just lit the stove in the basement and the smell of french fries is coming up the stairs. I have enough weight control problems as it is. Reminds of an old friend Warren who was an overweight pig farmer. His next door neighbor was a farm stand who cooked fresh doughnuts in oil every weekend which they sold in great quantity. He could not stand it.

I will throw in another one. Every leap year for those with base heaters/burners, drag it outside and take a leaf blower and blow out those passages. I don't care how well you clean it, you will be amazed. It has to up efficiency.

You've gotta figure that if You lift the rust using a product that doesn't leave a corrosive residual,then You've got a shot at keeping Your unit right. I like the PAM idea afterward for using something that has a little creep-ability to protect those crevice,dimple and rust holding pocket spots..... As far as the weight gain problem,simply reflex and think of Roseanne Barr or Rosie O'donnel disrobed. That will not only dispel any aura of appetite,but You may actually lose weight just from fear..... Trust an Old Lunkhead such as myself,it works !

Oxides verses ox hides ? No thanks, I'd rather put up with the rust. :D
