HG tile stain remover was developed especially for removing grease and oil stains from tiles as well as for porcelain tile stain removal. This (ceramic) tile stain remover is also suitable for removing epoxy residue.
For best results, follow these simple steps when using HG tile stain remover (HG product 21). First, give the bottle a good shake before pouring it onto the area you wish to treat. For heavily soiled areas, use the stain remover undiluted. For lighter dirt, mix it with warm water at a maximum ratio of 1:5. Next, scrub the area with a brush and let the stain remover sit for 5 to 10 minutes. Finally, rinse the area thoroughly with water.
