To maintain respect, you only need to recite the Buddha's name three times or more, and you can burn it or dispose of it. If you really don't understand or dare to do it, you can take it to the temple and let the monk help you deal with it. Remember that these are just forms, not important. What matters is the heart! Respect and sincerity are the most important things. The so-called "sincerity is the spirit" means this.

Jie Quan Master, a disciple of Master Hongyi, one of the eight schools of Buddhism, had a similar case: a layman wore navy blue clothes (navy blue clothes are Buddhist cassock) to the temple for morning classes, and later got dirty. After washing, he was confused about how to deal with the washing water. He felt disrespectful when he fell into the drain and toilet, so he fell to the ground under a tree. Finally, he went to Jie Quan Master with water, and Jie Quan Master listened. Hehe?
