I have a sodium silicate sealant in my car and need to find a way to soften it Poured Blue devil sealant and found that it clogged my engine. Can someone who knows about chemistry and cars maybe give me any ideas on how to solve this issue?
I do not know much about engines, but from a chemical point of view, the clog that formed in your engine is most likely a hydrated silica. This compound is very insoluble and unreactive - there are only few things that can dissolve silica, e.g., hydrofluoric acid or a hot concentrated solution of sodium/potassium hydroxide, but I wouldn't pour any of these to an engine. Therefore, it seems that your only option is to dismantle the engine and try to remove the clog mechanically.
