update: i have succeeded in pulling out all of the material that was stuck in the hole. Thanks to suggestions about using apoxy solution i cleaned it completely out usng a mixture of hot/lukewarm water and using the apoxy to get the rest off of the sides. I put the cleaning rod in yesterday and now it looks even more beautiful tha it did when i bought it a month ago. Thank you everyone and i`m sure i`ll have more questions in the future about different problems that might come up.
