Cleaned the bolts and nuts with acetone today, I have soaked them for a while then cleaned them with Q-tips, then towel dry them, and repeat once again. The result however is the same, I attached the bolt to a new electrode, 5 mins and the reaction …

Thanks @wjcroft I will report back after I try it.

Ok so I cleaned the bolts with Servisol 10 which I normally use to clean potentiometers and switches and I always found it good to cleaning off any residue from electronics parts. I also tried cleaning them with hot water and washing up liquid which…

Yes I did try cleaning the bolt with isopropyl alcohol, however it didn't have any positive effect and the electrode was still reacting with it.

Just a quick update, the electrodes did react with the stainless steel bolt however measuring with a DMM I didn't observe any significant loss in conductivity.

I got mines from eBay A2 Stainless Steel. But I also read a post https://github.com/OpenBCI/Ultracortex/issues/21 which describes the same issue with the recommended parts.

Thanks for your quick reply, I didn't realise it was coated plastic, its not stated on the product page. Within two minutes from mounting the electrode to I noticed a small band of oxidation around the bolt, in the next 10 minutes it has grown and…

Thank you for your answer William. I'm gonna go ahead and finish the assembly.
