I spilled shampoo on my laptop recently. gave it to the tech guys, they cleaned it and it was working fine. After a month suddenly the control alt and shift buttons were not working when pressed together. Now the shift key is not working. The tech guys say the mother board has rusted after the shampoo spill and it needs replacement. The laptop is working absolutely fine except the shift key. I think the tech guy is cheating me.Please help.

Rust is a specific type of corrosion related to iron. Sometimes people use the word "rust" to describe all types of corrosion. There may even be small amounts of iron in the components of the motherboard.
As far as a motherboard, corrosion can develop if exposed to moisture. According to the site madehow.com;
The primary ingredient in all shampoos is water, typically making up about 70-80% of the entire formula. ()
Therefore, your motherboard was exposed to moisture and could very possibly have some corrosion. Exposure to moisture is never a good thing for electronics.
Is it the cause of the keyboard malfunction? We cannot answer that with certainty without seeing the corrosion and knowing what circuits are affected.
