I have about 225 linear feet of 6" tile (porcelin, I think) from water level up, and stainless laders and handrail in and above the water.
We use a red scouring pad with a cleaning gel designed for the job on the tile which I think is less abrasive than 3M's green Scotch-Brite pads. We clean about once a week to remove the body oil, skin, etc that forms a scum :P It works ok- but I thought I would get some more advice before getting another bottle.
The stainless cleans up well with an automotive stainless cleaner, but takes a long time by hand. We may try a power buffer. It is clean and shiny underwater, so that is no problem.
Thanks for any advice and help!
