I dropped my iPhone 5c into my cereal and now it won't charge properly? - 1

I dropped it in my cereal last night and it wasn't even in there for 5 secnds I pulled it out and ran and dried it off. I tried playing music and it sounded muffled. So i took q-tips and cleaned out the speaker and the charger hole then i put it n rice over night. When i woke up it was working perfectly fine It charged normal and everything. But now it is night time and itwill charge but if i move the cord or l move the plug on the charger it goes on and off and on and off until i get it into the right postion. I kno what youre thinking its the charger. No it is not. I tried two different chargers on my phone and they both do the same. I even went as far as to try those two same chargers on my siblings perfectly working iPhone. And they worked just fine so i know its my phone i just don't know if continuing to use my phone like this will make it completely break or if it will be like this forever Can someone help me figure out what to do.

Yeah liquid can't move anywhere in 5 seconds. Lol
