One thing we take very seriously at Renue Systems is our commitment to R&D of deep cleaning practices. We recently introduced into our arsenal a new chemical suitable for some tile and grout situations. Grout cleaning in particular can be challenging for our customers. Many times hotel personnel becomes so accustomed to dirty grout that they think the original color is dark – but that is almost never the case. Lo and behold, the accompanying picture shows a small section contrasting the current color versus the restored version. Please click on the picture for a closer look.
