DOES THIS WORK? DISHWASHER TABS v. GROUT

When I bought my house it has the worst floor and counters. I could never get the tile grout white. I have tried bleach and steam cleaning. Well.. I noticed my dishwasher cleaning tabs did a good job, what about on my grout. I sprayed the counters with a natural based cleaner and then with gloves, I used a dishwasher cleaning tablets on the grout. It took two tablets. I put a timer on for 15 mins. Then I used a toothbrush and a nylon scrubby and hot water with a few drops of natural dish soap and scrubbed grout.Then I wiped counters. LOOK AT THE RESULTS AND THE. I TRIED THE FLOOR! Give this a try. It worked great on my tired old grout. I am not getting paid anything for these brands. I just had them in the house. You can use any brands that do the same thing.
