When i was younger I introduced clay on the speakers (without opening the up part), but i had this for a long time! Altough there is still clay, speakers work 100% fine. Is there a way to remove it?

Santi12008 , The link below will show how to disassemble the device, allowing you to then dampen clay with water, poking clay from speaker holes or scraping it off with out damaging internal components. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. Nintendo DSi XL Speakers Replacement
