Homebrew PCBs

If you are going to store it, preferably use a sealed glass container. 
Don't leave it in an open container as the fumes can make any nearby 
steel go rusty. Some plastic containers are slightly porous so over time 
acid fumes can escape and rust any nearby steel.

If you want to neutralize it, keep adding sodium bicarbonate (baking 
soda) or sodium carbonate (washing soda) until it stops fizzing. Washing 
soda is probably better because baking soda will fizz a lot so you will 
need to add it slowly. Another trick I have heard of is to mix it with 
cement. That way you end up with a neutralized block.

> DJ Thanks for the feedback. If I decide to re-use it in the short term what are the precautions I need to be aware of for storage of the solution? The reason I was planning on neutralizing it was that it was so cheap to buy and readily available that I felt it wasn't worth the risk of storing it. Your thoughts?
