Retro Clean is an eco-friendly soaking agent that safely restores age-stained textiles. It removes yellow and brown discolorations related to water damage, mildew, wood, coffee/tea, tobacco, baby formula, and perspiration. Just one soak will renew quilts and other delicate washables (like linens, vintage clothing, lace, and silk) to their original colors and vitality. Retro Clean is non-toxic, hyp-allergenic, and biodegradable. For more information, to watch a tutorial and to learn about the companion product, Retro Wash laundry powder, see www.retroclean.com.
