Tristar Prod 16 OZ. RESTORE 4

The media could not be loaded.  I bought this stuff at the recommendation of my realtor, to take care of an old bathtub in the house I just bought. It now looks brand new! It was easy to do. You spray it and then let it sit a few minutes and then scrub it off with the included brushes. It was fast and didn't take a ton of effort. Done in probably 10 minutes. The fumes are pretty bad. I bought some masks because I had read that in the reviews before.

This really works well for me. It has made my tub and shower look so clean and new. I advise wearing gloves and vent the area well. So many cleaners advertise that their product cleans the best, but in experience this really does.

Bought for my worn out kitchen sink. Works wonderfully. Tries it on my fiberglass shower. Worked amazingly welll very satisfied

It does the best job of any of the grout cleaners I have used to date (and I have used many of the 'supposedly' top rated products.) However, it still requires me to apply it, let it stand for about half an hour and then get down on my knees and scrub. But, I had done this with other products and didn't get great results. At least with Restore 4, my efforts at cleaning get results.

I love this product!!! I rehab properties and first used this product about a year ago. I bought a foreclosure where the tub had significant scale, rust and grime. I bought multiple cleaning products that took care of the surface cleaning but didn't tackle the scale and rust. I was disappointed I wasn't able to save the tub and didn't have a new one in the budget. A local home improvement store had a Restore 4display that caught my eye. It was a little pricey but felt it was worth one more try before replacing the bathtub. To my amazement It took the scale right off; rust took two applications. I thought I need to keep Restore 4 on hand for the next project and found that the store wasn't selling it anymore. Thankfully I found it on Amazon and at a better price. I used it on three more properties including fiberglass and cast iron and had the same success. I have a rental where the cast iron tubs finish is worn and although it cleaned well there's nothing that can be done about the finish. I highly recommend giving this a try.

I had a stain in my fiberglass shower floor that no other product could get out, so I was hoping this product could do it. Unfortunately, after applying twice, the product still wasn't able to get the stain out. The product works some, but I don't think it's any better than a scouring cleaner (such as Comet) or a Magic Eraser.

The product only works well at full-strength. I used it on porceline bathroom tiles that were very old and had lots of tiny stress fractures. The product didn't really work very well and the smell was hard to take in an enclosed, small space, even with a fan going. I had as better success with white vinegar and water!

Tristar Prod 10 Oz. Restore 4 does work with a stiff brush and lots of elbow grease. My bathroom ceramic tile floor look great when I finish. I put it on with a brush and let it set for awhile and then used the stiff brush on the grout. It is definitely worth it, regardless of the hard work which I am not allergic to! I am so proud of the looks of my floor. Camelot 40.
