NEVER, EVER SCRUB UR BATHTUB AGAIN. I still thought I would have to scrub..."U DO NOT SCRUB". My tub shines...(I used 1 cup Heinz Cleaning Vinegar, & 1 cup blue Dawn (must be blue)". Heat vinegar & pour into spray bottle. Use a good spray bottle. Add dawn to vinegar & shake. It will be a little thick. Spray on tub & leave 1 hour. Then just rinse off. UR going to Love this..no more scrubbing. The Cleaning Vinegar was w/the vinegars at 1 Walmart & with the cleaning products at other.
Tub Cleaner - Heat 1/2 cup white vinegar in microwave for 90 sec, pour into a spray bottle. Add 1/2 cup BLUE DAWN dish soap. Shake gently to mix. Spray on surface, let it sit 1-2 hours. Just wipe it away then rinse with water. Should also take soap scum off shower doors and tile! THIS STUFF IS AMAZING!
