Review: Fantastic product! - Worked great for a nylon puppet fleece that I use. It helped give an even dye job and is well worth the price. There was no unpleasant odor or anything. Love it!
Review: Not just a dye setter for home dying, but awesome for prewash of new clothes that color run & to keep your black clothes black! - Though I initially bought this for dying fabric, I find I used it often on brand new designer clothes to set the dye from THEIR processes so I can avoid having to be so "specific" with my basic laundering. Most of my clothing tags say "launder separately, inside out, cold/cold delicate wash" I have found that more often than not, it is due to dye color bleed NOT the fabric itself...I don't know about anyone else but I don't have time to launder every single item of my wardrobe separately lol...its not like I only wear a couple of different colors. I actually wear a lot of different bright "jewel tone" colors along with the basic darks so simply separating like colors is not recommended for many of these items either. So, when I buy something new, I wash it in this FIRST, according to instructions until I have no more bleeding. I have yet to have color transfer issues on my clothes after using this and mixing my laundry so I would say this works like a charm to set dye! AWESOME to keep your blacks actually black as well. :) Of course, once I treat my new clothes with this, I do wash on delicate, inside out, on cold/cold but not because of color run but just to keep them their brightest and darkest for longer. (I use detergent specific to darks etc. as well...I find doing these things and starting with this, my clothes look new even a year or more later, with no fading.) Using it this way, it makes it well worth the price! (because lets face it, it is pricey for such a small bottle...but not when you calculate the savings of your hard earned money forked over for a new wardrobe sooner just because of fading issues like your favorite black pants are now gray! This way you can at least hang onto things until the styles have changed enough that you WANT new clothes lol.) When dying your own fabrics, well...lets face that too, few hobbies are cheap lol so it is what it is price wise.

## Questions & Answers

**Q: Can I use Synthrapol on colored fabric or just white?**
A: This is specifically made for colors although I'm sure it's fine to use on white.  I use it in the washing machine after I tie-dye clothing to keep the colors from bleeding together.  However, I have learned in my new "modern" washing machine it does not fill up with water fast enough and colors can sometimes bleed anyway.  I have to mix the Synthrapol in water first and add it to the machine immediately or do it in a bucket, agitate the tie-dye clothing, and then pour it all in the washer.

**Q: What is the difference between Synthraphol and Retayne?**
A: Retayne fixes dye to fabric and should be used to wash fabric that bleeds or may bleed PRIOR to using in a quilt or other project.
Synthrapol is a detergent that suspends dye particles in wash water so that they do not reattach to fabric.  Under the best circumstances it can help salvage a completed quilt which has been found to include bleeding fabric(s).

**Q: Can this be used along with Oxiclean in the washing machine?  I need to soak clothing in hot water to remove stains but I want to prevent color bleed.**
A: Yes no problem.  Perfect for that.  This is called backstaining and is exactly what it was meant to prevent.

**Q: Can you use this Synthrapol without the recommended added soda ash?**
A: Synthrapol is a detergent intended to wash excess dye out of fabric. Soda Ash is used in the dying process to help the fabric retain color better. Between the two, Soda Ash is the more necessary component to the dye process, but both are recommended to produce the highest quality finished result.
