yantra maintenance problem

[Guest guest]

Dear Sh Narasimhaye Ji,

 

I have few uncoloured copper Yantras at my altar. Every Friday or Sunday

I rinse them gently with Water and immediately dry them with white cotton

cloth. On auspicious days, I do milk abhishek also and then again wash them

with water and then dry them. But even after that the Yantras have developed

some stain due to atmospheric effect or due to rinsing. The permanent stains

are mostly at spots where chandan/ vermillion/haldi dots are put. In such

cases I clean them with salt and Lemon. They become clean and sparkling

after that, but some sections of permanent stains have happened which do not

go. Even if they do not develop stains , after some time they become dull

and loose lustre and necessitate cleaning with salt-lemon.

 

My queries are:

 

1. What is the ideal way of maintaining Yantras? What should be the

frequency of cleaning them and how it is to be done?

 

2. I read somewhere, If Yantra become peranently stained or loose lustre it

should be left at temple or disposed in water, as it may become malefic.

What do you say about that?

 

Warm regards,

 

Vishal
