Jacquard Synthrapol Textile Detergent, pH Neutral Fabric Cleaner for Dye Preparation and Washing, 8 fl oz, CHM1009

This did exactly what it was intended to do.

I used to wash a very large patchworked,embroidered, machine quilted bed quilt...to lock the colours, remove any construction marks I might have missed and the "terial magic" stabilizer used for free motion quilting. Perfect...it did the lot AND the quilt felt fresh and soft. ps...I hand washed the quilt in my bath and drip dried it over the bath on a clothes airer. Crazy to try it, yes...but it worked brilliantly. Synthrapol is certainly not just a detergent. Highly recommend.

Easy to use and really did soften the yarn of my hand knitted Nordic cardigan

Not sure if it is the product or it is just not working for my quilt...it will remained stained

Using Synthrapol to ensure some dyed fabric was totally clear of any unabsorbed dye before use was recommended by a friend because this detergent is unique in that it holds any dye particles in the rinsing water. After using an entire bottle I am of the opinion that any strong washing detergent works equally as well, in fact my usual washing up liquid took far fewer soaks than Synthrapol and is much cheaper. A note on shipping: this item took almost 4 weeks to arrive which is excessive. It wasn't psoted from the UK but from the European mainland, so if you need it in a hurry, it's not worth ordering at all.

Very disappointed that this did not work to remove colour's runs on my cream ottoman cover. I followed directions to the letter and it made absolutely no difference to intensity of number of runs on item I ended up using two other methods to remove/ reduce runs with limited success but still, these methods made a positive difference unlike this product. As synthrapol 's primary use is for stripping oils and finishes and removing excess dye after hand dyeing ( which I do) I will reserve judgement until such time as I can use this for other applications. 2 stars down as it did not work for one process mentioned above 3 stars as I didn't realize a product like this existed until I researched how to remove red colour's runs off cream cotton upholstery fabric, but I do have other multiple uses for this product It's not available in Australia except through Amazon from what I can see. So my 3 stars are high hopes ,it will make dyeing a lot easier with better results. I have about 30 items to dye, so will update once this is done

This product is very good and it was used to wash the “sizing” out of a linen/cotton dress before I used a Procion MX dye to dye the dress a different colour.

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!

It works when following instructions so read and follow as directed. There’s no smell and a good value as a little goes a long way.

I use Synthrapol to wash anything I've knit with yarn that I've dyed. Synthrapol gets the excess dye out and suspends it so it doesn't absorb back into the knitted item. It works good on some stains you might get on your clothes, too.
