Removing rust stains

[HectorLooi]

Recently there has been a lot of talk of how to remove rust. Vinegar, Coke, phosphoric acid, Evaporust....

Just to add my two cents worth. I have a date ring and day wheel from a Timex electric that had a bad battery leak until it's non salvageable. There was a lot of rust stains on them. I used dental etching acid which contains 35% phosphoric acid.

I left it for about 30 mins, gave a light scrub and repeated. Here are the results.

Good jobe.

You will get shinier results on chrome plated parts like bridge, mainplate so on, if you soak 24 to 48 hrs in just coke and use powdered detergent on tooth brush to scrub the rust away and keep brushing under tap water as a rinse.

Nice work, I know the day ring can get brittle and crack while manipulating back into position during a service.

Easy to guess how I came to find this out! good for me I had a ready supply of replacement
