thanks,

Me thinks in order for that to be effective, a 'sacrificial' bar would need to be running through the center of the tube. As I understand it, the process is 'line of sight' as far as the reaction is concerned. I have thought the 'potato' method would be effective on the inside(if you put some inside it).

I haven't tried electrolysis yet. I'd like to, but don't have a battery charger or some of the other stuff necessary.

jpg your 100% correct. For rust to be removed from the ID of the tube, you would have to have have a rod (positively charged) running thru the negatively charged tube. If anyone were to do this, MAKE SURE THE ROD DOESN'T TOUCH THE TUBE else theres a very good chance you'll be saying "bye-bye charger"!

Charger, craiglist, $10
Baking soda, supermarket, $1
Scrap sheet metal, craiglist, free
Plasitc bucket, home center, $5
Water, your faucet, $.0001

Results - Priceless

Did you use 'baking' soda or 'washing' soda???

I have to say this site is getting to be my most favorite of all sites it gets to excited about working on my SS and getting it in top shape.

Keep up the great work guys and I hope one day I will be able to help out as much as you guys have helped me.

Place baking soda in an oven for an hour @ 300º. It becomes washing soda.

The question was what did HE use?

for the potato method, I was wondering if the potatoes had to be line of sight (shouldn't need to be) or if the solution would do much inside. seems like it wouldn't be any worse than where 2 tubes were laying against each other in the ferment.

for the electrolysis, I haven't tried it (yet) but I had caught the line of sight need in the discussions here. I ordered a rod from SS that came in a mailing tube with plastic end cap wheels. they were poor end caps (the rod arrived hanging out one end), but they might make a good electrode positioner for an electrode rod down the center of the tube.

like I said, I am definitely looking forward to heathicus' report.

I used baking soda but first cooked it at 300 *F for 1 hour. The heat drives off an H2O and a CO2 molocule turning the baking soda into washing soda. Sooooooo, I guess my answer is....washing soda but homemade,

I've read where baking soda works just as well but I don't know the pro's con's if any. I wouldn't try it just because a majority or reading I've done says washing soda.

I spent a week looking for washing soda and it just ain't in San Diego. They don't wash much here:eek:
