What It Is
Metra 390879 is a heavy-duty rust stain remover supplied as two white tablets. Each tablet treats the toilet bowl with every flush and is safe for all plumbing and septic systems. The formula contains no bleach, caustics, phosphates or dyes. It works in both white and coloured toilets.
When the Upgrade Is Worth It
Switch to these tablets when liquid cleaners require frequent scrubbing or leave residue on coloured porcelain. The drop-in format delivers continuous treatment without repeated measuring. Buyers who prefer a spray application for vertical surfaces or sinks will not be served by this tablet form.
How It Fits Your Routine
Drop one tablet into the toilet tank to activate automatic cleaning with each flush. The system prevents hard water build-up continuously, freeing you from scheduled manual scrubbing. No additional tools or protective equipment are needed for regular use.

Questions about this item
How many tablets come in the box and where do they go?
The box contains two tablets; drop one into the toilet tank so it releases cleaner with every flush.
What is the correct way to install a tablet and what mistake should I avoid?
Place the tablet in the tank away from the flush valve — putting it directly under the water inlet can dissolve it too quickly.
When will I need to replace the tablet and how can I tell?
Replace the tablet when the blue colour in the tank water fades, typically after several weeks of regular flushing.
