Hi folks, after having fully electronically (full recap and change some germaniums) repaired and cleaned key contacts (in the contact area only with isopropyl properly) an Elka Panther/Capri Duo, i decided to clean in total and "perfectly" the whole bus bars as they were pretty dirty/black tarnish/rust. You know that feeling you have sometimes when everything is perfect and youy just want to have all "shiny/perfect like new" ...
Before that (having cleaned them at "contact area" only with 99% isopopyl) all keys were working fine (well only 2-3 out of all keys from both manuals were a bit scratchy).
So, due to its big mess and dirty and because it was really hard to completelly remove that black dirty layer with q-tips and isopriopyl, i was looking for a "lazy" solution for total bus bar cleaning, smthng that i could just spray and then rinse out with isopropyl. So, as i was in a super market i grapped one of those cheapo Silver Polish Liquids, like "Silvo" and so. (Actually it is another brand for Silvo Liquid one, i was told its the same). Cosmetically it did the work perfectly, with a little extra q tip work , bus bars were 100% clean and i was happy.
BUT now many keys are scratchy, i manually move the little contact needles to the upper busbar and it does that scratchy sound everywhere.
I am worry aboutr if i made huge mistake using the Silvo (for start i know i should have used Brasso instead of Silvo- but i dont think its that) i wonder if those are too agressive/abrasive and i am afraid if maybe i did somthng bad to bus bars or contact needles like damaging any plating they probably had ? Actually the little "contact needles" look pretty solid, like they were before, i mostly worry about bus bars. Do you know if they have any plating and what material could be? Brass, palladium plating maybe? Solid?
I called the company that manufactures the Silver Polish i used and spoke with a dedicated / experienced guy who was te chemical guy of the company. He reassure me at first that any damage/abrasion could have done and that i should rinse with water as this product is water based and not organic (like isopropyl,diclorometahne,acetone etc.) so the pure isopropyl that i used did not rinse it.
I did rinse with water and then isopropyl q tips and at first problem seemed to be gone but then keys turned scratchy again.
I have also used Teslanol T6 (same as Deoxit D5) but problem remains.
Any thoughts? I am really dissapointed :(
