Chosen Solution

Hi every one, i have one plus 6T, i have spoiled a hot liquid candle wax on it, and i was able to remove the damage from the screen (thanks to the screen protector) now am left with only 3 holes for the speaker to listen from (the rest is blocked with the wax), i have tried to apply some heat from the hair dryer with no luck, what do you think is the best way to solve this issue ?

Try putting the phone is a ziplock and use a hair dryer, the wax should flow out. Alternatively follow the teardown guide ( skip removing the motherboard) and clear out the wax form the inside. OnePlus 6T Teardown

Try using a needle or a slim pin to clean the speaker holes. If you are careful, you can just take out the wax without damaging anything.

I usually wrap a glue-dot around a cocktail stick and use it to clean the dust out. I find that glue-dots are just the right consistancy to pick up dust, but still firm enogh not to get clogged in your phone.

Vacuum cleaner and a stiff toothbrush. Be careful not to push the wax further inside and damage the speaker.
