Hello, does anyone know how to clean shower doors so that they look clear? I have tried different cleaning sprays but to no avail, they still look streaky and have deposits on them after cleaning. I have recently tried 0000 steel wool, but it only came up marginally clearer, I tried it in conjunction with Viakal vinegar spray too. I'm beginning to think it's just that I don't have enough scrubbing power in my wrists.
