My wife might kill me... I was cleaning kegs the other night and was careless and spilled a good portion of concentrated cleaner on the tile. It is discolored now and doesn't seem to want to come up with soap and water. Anyone know a way to get this up or am I up shits creek?
This is simple residue, not permanent damage. If you have Star San, make up a strong solution, maybe 20%, and let that sit on it for awhile before scrubbing, and rinsing very well. It may take several repetitions if the tile is not sealed well. Make sure you wash off all the Star San residue. It could damage the grout over time.
