These work really well on the glass shower doors to remove those tough hard water stains. We use the same process, as before, by applying the Barkeepers Friend to the scrubber and using elbow grease to really scrub the stains off the glass.
Once it has gotten a good scrub we wash it off and take a look to see if it needs another application or spot check some areas. If it looks good, we then spray the glass cleaner on, to both sides of the glass, to give it that final shine.
Barkeepers Friend works great on the other areas where the hard water likes to accumulate: the faucet, handles and shower heads. Again, if you’re using it we always suggest to spot check with the product before applying it everywhere.
