weird issue with my keyboard

[Vendor]

so i have my mechanical keyboard for more than 6 years now and it was running fine up until recently where i got a minor issue where holding down shift+ctrl and pressing up key won't select more than 1 line although using left arrow works fine and can select word after word, iirc it started happening 3 months ago, i dropped tea on my KB back in sept last year but it was fine for few months after so i am not sure what's going on here. It's a local Indian brand here called TVS and their Gold model, even Linus has a video on it titled "Why does India love this keyboard?" I have the PS/2 connector variant of it and currently i don't have enough to upgrade my keyboard, i would rather utilize it for something more worthwhile, it's not even much of a issue but it would be ideal if i can fix it.

I would not think tea alone would cause problems, unless you had cream and/or sugar in it. That would be bad. I am a little confused with the timing because you said you spilled the tea on it "3" months ago, but it worked fine for a "few" months after that. So this problem just started? It may or may not be related to the tea spill. If only a tiny bit got to the switch, it may have just taken some time for the sticky tea residue to finally collect enough dust to "gum up the works".

I recommend you temporarily borrow another keyboard and see if it works properly, just to verify the problem is with your keyboard.

If it is your keyboard, then most likely the only solution is a proper cleaning - assuming the problem is just dirt and grime. Being mechanical, you should be able to clean it, if you can get to it. You will need to get a keycap puller so you can safely remove the keycaps to gain access to the switches.

There are lots of videos on how to clean the Cherry MX switches with lots of different recommendations for the cleaning solution. I recommend using CRC QD Electronic Cleaner or WD-40 Electrical Contact Cleaner. Typically, the power from the spray is enough for most cleaning jobs. But if the dirt is stubborn, spray with the contact cleaner then give it a soft scrub with a acid brush.

I also recommend you take a photo of your keyboard before you start pulling the keycaps so you have a layout to follow when putting the caps back on.

Good luck.

thanks bro, i will give to my brother to clean it and before that will also verify if other keyboard is fine, he's good at it and all kinda pc stuff, i am usually kinda scared to disassemble and stuff because of my bad experiences of breaking things in the past. He cleaned his own couple of months back.

Sounds like a plan. Let us know how it goes.
