Magic DIY Tub And Shower Cleaning Solution That Works Wonder

My Facebook Page Follower Linda Gail Hutto Towson gave me a challenging case. She has a fiberglass tub in her house since 1983. She has tried such method as using oven cleaner to clean the hard water stains and build-up without much success. Linda would like to get some suggestion to make her tub shiny white again.
I have done some research and came across this magic cleaning recipe on food.com. The key ingredients are vinegar and Dawn soap. Nothing smells chemical. I haven’t personally tried it, but the reviews from people who have tried are great. Many people suggest that they were able to clean their tubs easily with this solution.
Does it work for Linda? I don’t know yet. I hope Linda will try it and report back.
Meanwhile, if you have a tub cleaning solution that might work for Linda’s case, please do share in the comment area. I hope both Linda and a lot more readers would benefit from it. Thanks!
