How to Use C-thru Shower Shield 

It should take you about 2 minutes to apply a coat of Shower Shield to the inside on a typical clean glass shower.

To apply, put a small amount of Shower Shield onto a clean dry cloth and apply sparingly by wiping over the surface in a back-and-forth direction. Allow to dry and your shower or other surface is ready for use. No polishing or buffing required.
If this is the first time you’ve ever applied Shower Shield we recommend you apply a second coat by wiping over the surface in an up-and-down direction to make sure you cover any spots you may have missed in the first application.

Undertake normal cleaning with a mild detergent or glass safe spray-on-rinse-off type cleaner. Every few weeks, after cleaning, ensure surface is dry then reapply Shower Shield.

Every 2-3 months give a quick clean with C-thru Water Spot Remover to eliminate any contamination build-up and re¬apply Shower Shield.
