Jacquard Synthrapol Prewash and After Wash Liquid detergent for Dyed or Painted Fabrics, Industrial Strength, pH Neutral, 8 fl oz

This did exactly what it was intended to do.

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.
