IBERIA WHITENING REMOVER is designed specifically for white fabrics. This versatile product provides dual benefits. Important to note: Iberia Color Remover is exclusively safe for use on white items, as it may unexpectedly affect other colors, including darker shades as well as lighter ones like beige. Beware that metal components such as buttons and zippers that aren’t stainless steel could sustain damage. For larger pieces with mild discoloration, you can use 4 packets of Iberia Quitadeñedidos while washing. For items with severe fading or smaller articles, we suggest applying the remover manually. To lighten fabrics before dyeing them to a lighter color, utilize Iberia Hand Bleach Remover. While the fabric won’t reach a pure white state, it will be prepped for dyeing. Ensure you refer to the dyeing instructions to finish the process successfully.
