“I live in California where hard water combined with water use restrictions (‘If it’s yellow, let it mellow…’) leads to hard-to-clean toilet bowl stains. Two weeks in and I am amazed! No new stains. I highly recommend TrueClean.”
Linda – California
Timeframe: 2 weeks
Water type: City hard water
“TrueClean has been in place for only a week and the change is amazing. We have hard well water and nothing else has worked. Clean isn't the issue. Hard water staining is. Even the tanks were solid brown and encrusted. Not anymore!”
Simon - Desborough
Timeframe: 1 week
Water type: Community well
“I used to live in Washington state and the water is so hard on toilets. I was having to use a pumice stone every time. It sucked. Clipped these into the tanks 3 weeks ago and haven't had any hard water deposited since.”
Jane Wilson – Washington State
Timeframe: 3 weeks
Water type: Very hard city water
“We have well water and get black slime in our toilets. These do come with an extra tube that’s longer, which I appreciated. It worked out and the water line stains are finally under control.”
Unknown – Well Water Home
Timeframe: 3–4 weeks
Water type: Well water
