First before you worry about the power pads you'll need to clean all of the junk off of your board.
Follow this IFIXIT guide: MacBook Core 2 Duo Logic Board Replacement and carefully scrub with a soft toothbrush with distilled water (not tap water!) working within a deep well'ed pan. Then a second bath of 85% or better isopropyl alcohol which will help in removing (drying) the water. Once the board is clean of the corrosion let it dry on a warm sunny window sill for a few days. You will need to also clean off the thermal paste before you dip the board and apply a fresh coat once you are ready to put it back in.
One of the problems you face here is other components could have also been damaged so the costs could get steep! A new logic board will be around $250 US a new keyboard $120 US for starters.
It might be wiser to locate a used system which supports a newer OS and apps. Sadly, Apple no longer offers OS maintenance and many apps today won't run on this older system. I would strongly recommend locating a i5 or i7 based MacBook or MacBook Pro. In the long haul it will be a better direction.

As for the power pads in your system they are marked SMC Reset near the fan connection on the logic board.
I already did that. that's the image after cleaning the logic board using a alcohol with 70% solution using toothbrush. after that. I let the logic board dry for 4 hrs then i try to turn on using keyboard. still not working, then i try using power on pads. Still not working. I think the logic board is damaged.
Should i give up and buy a new laptop or should i wait for couple of days and try turning it on?
After the water was spilled for 5 secs my MacBook suddenly shutdown then I just panicked. So I press the power button to check, my mistake was turning on the MacBook when the logic board was still wet. I think that was the reason the logic board is damaged.
At this point I think you'll need to throw the towel in ;-{
I think getting a new system would be the wiser choice here (used or new).
Ok men thanks. I appreciate your help. And one more thing. Can i still use the hard disk ? i dont know if it still working but is it possible to use it on another pc?
Yes you can recover your stuff from the drive using a SATA to USB adapter like this: Startech 2.5" SATA to USB adapter. As your drive is quite old (slower and smaller than whats shipped today) I wouldn't recommend putting it to your new system. Your drive is only a SATA I (1.5 Gb/s) while most of the drives in the newer systems are either SATA II (3.0 Gb/s) or SATA III (6.0 Gb/s) besides many hard drives are much larger 500 GB, 1 TB and even 2 TB! So they can hold a lot more data. Depending on what you get, you might get a faster drive like a SSD over a traditional HD.

@jojoo just to answer your original question and clarify the location of the power-on pads, not to diagnose your board. The SMC_RST pads are not to be mistaken for power-on pads.
In the images you posted are after the cleaning, you can still see plenty of gross contamination. I suggest that you continue to clean with a isopropyl alcohol greater than 90% solution. Remember that a 70% solution still has 30% water. After proper cleaning you could go ahead and see if you even get power to the board. Of course if you do not have the proper tools and knowledge it might be easier and less expensive to replace it like others already suggested.

Thanks for the answer @oldturkey03 ill try to clean it again with 90% isopropyl. I just cant give up with this macbook cause we have financial problems so this is my only macbook (or laptop) btw my only tool is a screwdriver, i dont have any spludger and one more thing. should i buy thermal paste for CPU? is it required in cleaning ?
Yes because you do want to clean the whole board properly.
Okay thank u so much men. ill just clean it again after i buy alcohol and thermal paste.
