No. You only use it once and you're good to go.

You can order it here or try your LQS.

I think you're better off using Synthrapol for batiks.
Check the Dharma Trading website.

Thank you EasyPeezy... now I know how to use it if the need ever arises. :)

Retayne and Synthrapol do different things. Synthrapol washes out and captures excess dye and keeps it from depositing back on the fabric. Retayne helps to better "set" dye to the faric. I hand dye and use both: Syntrapol to get rid of the extra dye and Retayne to keep what did set on the fabric "attached" better. Batiks sometimes have extra dye that hasn't been fully washed out so Synthrapol might be better, but it won't "set" dye that has trouble attaching itself.

I use Retayne on batiks with gret sucess.

I just wish it was for sale here. Sigh.

I just finished talking to the people at Dharma Trading. http://www.dharmatrading.com/index.html

You can get Retayne shipped internationally to most countries. Check their shipping info link. They are really great people. They have the patience of a SAINT to answer all my questions.

The dye makers need to be introduced to this product! We would be very happy campers!!! :-)

I use Shout Color Catchers, purple is the color that bleeds the most.
