Question 1

Can this be used after tie dying to help retain the colors? If not, what is suggested? Thank you.

Accepted Answer

Hello Melody and Thanks for the Question. Your garments should be soaked in a soda ash solution prior to tie dye for a minimum of 20 minutes. I like to mix appx. 1-1/2 cups per 2 gallons of warm water. The soda ash helps expand the Cotton Fiber giving your dye the Maximum Absorbtion. You can also add urea to your dye to help give The Dye a more Vibrant look. I use appx 1/4 teaspoon per 4 ounces of dye mix. This is Assuming you are tie dyeing cold water procion mx Dye on 100% cotton Fabric. They do make cold water dyes for other fabrics such as polyester & Nylon but I find the colors just don't stand out like they do with cotton.I hope this helps you and best of luck with your tie dye Scott

Question 2

is this item sodium carbonate, or sodium hydroxide?

Accepted Answer

It's sodium carbonate. This exact product is also sold as a swimming pool pH increaser. Sodium hydroxide, or lye, should not be used to tie-dye. Likewise, this product (soda ash) won't help you saponify oils for soap, or clear a blocked drain like lye will. Sodium Hydroxide, improperly mixed with water, can burn holes through plastic and cause severe tissue damage. Soda ash, mixed with water, will dry your hands out for a day.

Question 3

please confirm that this is pure soda ash  (aka: Na2CO3 sodium carbonate or washing soda) with no other additives... I need to raise my Pool PH

Accepted Answer

That's what it is, but you can buy the same thing cheaper (for swimming pools or as a fertilizer) if you need larger quantities.

Question 4

What is volume ie. cups of package?

Accepted Answer

One cup weighs about half a pound, so this package has about 2 cups.
