A full polishing range.
From cutting and one-step correction to final finishing.
The bathroom-facing side of a pane can encounter different contamination from its shower-facing side. Identify the treated faces and use a suitable routine for each.

Use the coating record to identify which faces were treated and with which product. Do not assume both sides received the same application. Keep factory treatment information connected to the actual exposed faces.
Record dust, fingerprints, styling-product residue or other observed marks separately from shower-side deposits. Avoid choosing stronger descaling chemistry for every mark simply because the surface belongs to a shower enclosure.
Follow the relevant glazing and coating care guidance. Keep tools suitable for the contact and free from transferred bathroom residue. A cloth used on one contaminated area should not be assumed ready for the other face.
Review the dry appearance and record recurring problem locations. Share the face-specific method with anyone cleaning the bathroom. If a reported mark is hard to locate, request a contextual photograph showing the side and nearby fitting.
Confirm suitability for the actual finishes and care needs. Similar appearance does not establish identical treatment history or contamination.
