I am a HUGE fan of Scrubbing Bubbles brand (all but one product I’ll mention in a bit).  Their Foaming Shower spray is AWESOME!! You barely even have to scrub the bath- just spray it on, let it sit a minute, then wipe it with a washcloth.  I bet it’d work on the sink too- but I just haven’t used it there yet.  I thought the can wouldn’t last very long- but it actually goes a long way.

Then there’s the Scrubbing Bubbles toilet cleaners- the fresh brush cleaning system is really good! And it was what I always used before I discovered the Clorox tablets.  I still use them occasionally though if needed.
The other toilet product they have is the toilet cleaning gel…….. NASTY stuff!! OMG this is the ONLY Scrubbing Bubbles Product I can’t stand!  When it first came out I bought some.  It’s a gel inside a tube.  You “stamp” the gel inside your bowl where water will flow over it but it wont be sitting in water.  Then it’s supposed to last a week or two.  The smell was sooooo bad later that day I was in there wiping it off, and I gave the rest of the tube away!
I even called the Scrubbing Bubbles Company to give them some feedback on the smell.  They thanked me, apologized that I didn’t like it, and then sent me a coupon for a free tube of another scent.  The trauma of the first smell kept me from trying the second one though!
