hello. i bought a second hand processor but the paste stains on it won’t go away. i wiped it with ipa and acetone but the stains still remained. if i start using it like this, will i encounter a problem or is there a different method to wipe it?

You could try using a small microfiber cloth with alcohol (you did mention previously trying IPA, but avoid using acetone as it can affect the substrate around the IHS) and even pressure to get a consistent movement while cleaning. If you brush your fingernail gently across the surface, do you feel texture? If so, it’s likely light abrasion and further cleaning won’t help.
It’s essentially cosmetic, you can apply new paste and carry on as normal. Paste is designed to fill those small imperfections to begin with, and you won’t notice once you start using your system. :)
