Hi Zeno. I'm Cindy. I use Scrubbing Bubbles with the blue lid. It costs a little more than the average cleaner, but I think it's worth it. The trick to using this product is to spray it on and walk away. Wait 15 or 20 minutes. Then come back with a damp clean cloth and wipe it off. It works great on hard water.
use armarol tyre shine, clean in small areas rub with non scratch cloth until you feel all the scum lift off. fantastic
Hi Zeno - This is the shower cleaner that we use to help keep grout and tiles clean and minimize the mildew - it works on kitchen grout too. Hope this helps! Hugs, Holly
