For a 725 frameset what method would you recommend, this chemical method or just a gental soda blast? Got some surface rust too
motoko-
Depends on how much time you have and how you value that time.
Both are fine.Red scotch attached to one of these will make light work of any mild corrosion...
A mild blast will leave a texture in the surface which can be useful as a 'key' for product but if the blaster doesn't know bikes, they can potentially damage threads or more annoyingly, get the blast medium stuck in the frame... no matter how hard you try, it will fall out at the crucial moment and ruin your finish... always.

Thank you.
What's your substrate material?
If it's stainless/aluminium/Ti, you can blob the stuff on and use use a pressure washer to hose it off.
You'll be done in 90 minutes.
