Methylated Spirits can be used to clean non-porous floor tiles, typically diluted with water (about 1 part spirits to 5 parts water) to remove grease and grime. This solution leaves a streak-free, fast-drying finish. For the best results, use a microfiber mop and make sure the mop head is well-wrung. However, be cautious when using it on porous surfaces, as it may cause slight discoloration, and never use it on painted or varnished surfaces.
