Yes they can! Our stain sticks are without doubt the everyday living essential every home needs! Aside from using them to spot treat stains prior to washing or as a handy interim stain remover on the go, you can indeed use them to also treat stains on fabric upholstery.
They can also be used on other non-fabric services. We have used them to clean white sneakers, remove food stains from kitchen benches and they are especially handy in removing red wine spills off the couch. Always patch test first to ensure the material is not adversely affected.
