Start by washing your fabric in warm soapy water. Then, start to boil a pot of water. Once it is simmering, add a package of Rit color remover and stir.
You can also use it in a washing machine but the stove top method will provide the best results because of the sustained heat.
Wet your fabric, and then add it to the bath of water, stirring it until you have reached your desired results which should be about 10-30 minutes.
I tried this method on a variety of clothes to show you how it works
The first item I removed color from was this a purple pair of pajama pants. The pants themselves are made out of cotton but I realized after I removed the color that the thread did not change color at all. So that is an important thing to note about clothing. Often times the thread used to sew together the garment is synthetic and cannot have the color removed.
The next garment was a cotton polyester blend that has a brightly colored pattern on the whole shirt. This was the least successful garment in this batch. The trim of the shirt had its color removed while the body stayed pretty much the same. It was definitely a little surprising, considering the cotton was the main fiber that made up the blend, but it’s important to note that you may not always be able to remove color with this method depending on the material.
The last three garments, we ended up doing two rounds of color remover.
The black shirt came out well after 2 rounds though not as light as some of the other items. This could be because of how dark the material was to begin with or because the shirt was not actually a cotton dominant blend, like it said on the tag.
The thread was also not changed by the color remover because it is fully synthetic.
The second round didn’t remove the pattern from these pants even though they are cotton. It’s possible that they are actually a poly cotton blend but Rit does say that it may not remove patterns and prints.
After the first round the jeans came out a bright yellow which was very surprising! After trying again the results were much better. If you want to use the color remover on blue jeans, keep in mind Rit states it will not work on the indigo color of many jeans.
