Metal Soap White Residue On Sliding Shower Doors And Metal Parts Of Shower. Is This Soap Scum Or Milder? How To Rid?

White residue on sliding shower doors and metal parts of shower. Is this soap scum or milder? How to rid? - metal soap

I pushed the door, the shower you can almost see through for the first time (outside of the texture design). Now you have white stuff everywhere and tried a variety of chemicals with the actual results and solid rub. Some are better than others. Same question in the metal parts of the shower and shower doors.

The white residue, I guess it could be soap scum, I do not know that (form, but perhaps even the traces of hard water but I doubt it because the apt manager is very good) in these things.

Ideas and advice would be helpful.
