The Showerdome is very easy to keep clean.

  • On top the Showerdome does get a bit of dust settling on top, this can be cleaned with a long handled feather duster annually or as required.  If your Showerdome is removable it can be easily take down to clean.
  • Underneath doesn’t require much at all as not much dirt or water staining gets up there, a micro-fibre cloth quick wipe is all that is required now and then.

Tip: If you would like to use a product on the Showerdome then we recommend Pledge. This not only cleans the Showerdome but puts an anti static layer over the dome to not attract dust. We use this when professional installing the Showerdome.
