This is the shower that my husband uses. I am — voluntarily — in charge of cleaning the fiberglass shower base (Swanstone). I am not very diligent about it. Obviously. Historically, I have used Lysol Basin Tub & Tile cleaner liquid in the spray bottle. It has “worked”, but it always took me like three applications, lots of letting it sit and soak, then wiping up over and over with a rag. It took forever and still there were always bits of scum left in the anti skid pattern of the fiberglass shower pan. Then the darn dirt would start building up again, fast and furious. So, you can see why I avoided the task: It was sisyphean. But ha!, disgusting fiberglass days are over!
I was trying ROG products and when I received the ROG3, it also said it would clean fiberglass. So I gave it a try and yowza: This fiberglass shower pan cleaned up like a dream — faster and better than anything I have ever tried before.
But, please note:
