Review: It really works—just let it sit for a long time - After reading so many reviews—some saying it works great, others saying it does nothing—I purchased it, then let it sit unopened for months as my fiberglass shower floor got dingier and cruddier until I couldn't stand it anymore. So I sprayed the stuff on the floor and sides of my shower and decided to leave it for 20 min, then check back. (Directions for the 16 oz and 32 oz differ for some reason; I agree with the 32 oz directions, as that is what worked for me.) When I checked, nothing had changed, so I scrubbed a little with the soft side of a blue sponge (w/nylon scrub on the other side), but nothing came off, so I left it for another half hour. Meantime, I reread the reviews. Turns out, I found more critical reviews than I remembered, so I got discouraged and thought I'd wasted $10. But still, after the half hour was up, I rechecked the shower and scrubbed a small area...and something magical happened. The stains/grime came off easily in that area, but in others, even heavy scrubbing (again, with the soft side of the sponge since you're not supposed to use abrasives on fiberglass) did nothing to lift the stains off. So I was encouraged by that one small area, which wasn't as dark and grimy as the rest, and wondered what would happen if I sprayed heavily and just let it sit for a long time. So I let it sit for about 90 min. Then when I scrubbed, more seemed to come off, so I was like, okay, I'll spray again and let it sit for another couple hours, which took me to 8pm. When I pulled back the curtain, I couldn't believe what I saw...I turned on the shower and without even using a sponge, most of the stains and grime had disappeared! I watched as the water rinsed away the product, and the floor was so much smoother and cleaner than it had been in years. It's not yet stain-free, but I cannot believe how much better it looks!! I just sprayed it again and will let it sit overnight and see what happens. I don't even know if using a sponge was necessary. It seemed to help bring up some grime, but I think just letting it sit was the key. I mean, you be the judge...these two preliminary photos show the results after spraying and leaving it for several hours, with a minimum of scrubbing. And actually, the first photo was after I had sprayed and let it sit for a half hour, then scrubbed a little. But the major stains are still evident. I'll add more photos as I progress. I just cannot believe how well this works, and just wonder if the bad reviews are because people aren't leaving it for long enough. The bottle says a few min, not a few hours. Good idea to test a small portion (I didn't because I'm impatient) to make sure it does no harm. But OMG. I'll be getting the 32 oz bottle now because I'm already running low on the 16 oz one. Last tip: Ventilate your area. I should've used a fan, but I was obsessed with my shower and forgot. Update a day later: With more sprays left on for several hours, it looks even better. I'm having trouble with vertical surfaces because the liquid dribbles down in thin lines, so I need to remedy that. Bottom line, where the liquid sits, it does the job. Review: Excellent product - Amazing, though I'm not using this for boats , but for fiberglass bath tub instead, they simply clear up the rusty water stains i could not clean up with other bathroom cleaners. No hassle. Rust stain just disappeared. ## Features - POWERFUL CLEANING ACTION: Specially formulated to tackle rust, dried fish blood, and leaf stains on fiberglass & painted surfaces - GEL SPRAY FORMULA STICKS: Clings to vertical surfaces for better stain penetration without run-offs or drips - REMOVES WATERLINE STAINS: Easily eliminates 'yellowing' tannic stains and tough waterline stains from boat hulls, plastic and painted surfaces - EASY TO USE: Simply spray affected area, let it soak until stain disappears, then rinse thoroughly with water - TARGETED APPLICATION: Gel spray design ensures precise application while limited drips & runoff ensure only the stained area is treated - MARINE GRADE QUALITY: Professional-strength formula designed specifically for boats, RVs, and other outdoor vehicles requiring maximum cleaning power - VERSATILE SURFACE COMPATIBILITY: Works effectively on fiberglass, plastic, and painted surfaces to restore original appearance and remove stubborn stains ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076QHX2M6 | | Allergen Information | Fish | | Best Sellers Rank | #64,541 in Health & Household ( See Top 100 in Health & Household ) #262 in Laundry Stain Removers | | Brand | STAR BRITE | | Brand Name | STAR BRITE | | Cleaning Agent Formulation | Stain Remover | | Customer Reviews | 4.0 out of 5 stars 2,057 Reviews | | Global Trade Identification Number | 00071247989168 | | Included Components | 1 bottle | | Item Form | Gel | | Item Highlight | Easy-to-Use Marine Grade Solution, Removes Tough Rust, Leaf & Waterline Stains, Maximum Cleaning Power Gel Spray | | Item Type Name | Star Brite 098916 Ultimate | | Item Volume | 16 fluid ounces | | Item Weight | 1.3 pounds | | Manufacturer | Star brite | | Material Feature | Thick and Adhesive | | Material Features | Thick and Adhesive | | Material Type Free | Unscented | | Model Number | 098916 | | Number of Items | 1 | | Part Number | 57-1187 | | Scent | Unscented | | Size | 1 Count (Pack of 1) | | Special Features | Concentrated | | Special Ingredients | Gel Cleaner | | Specific Uses For Product | Stain Remover | | Surface Recommendation | Fiberglass, Plastic, Metal, Wood, Glass, Stone, Concrete, Aluminum, Stainless Steel, Porcelain, Ceramic, Alloy Steel, Copper, Iron, Silver, Rubber, Leather, Suede, Acrylic, Linen, Cotton, Limestone, Vinyl, Linoleum, Marble, Granite, but not Fabric | | UPC | 071247989168 | | Unit Count | 1 Count | | Warranty Description | Limited Manufacturer | ## Product Details - **Brand:** STAR BRITE - **Item Form:** Gel - **Material Feature:** Thick and Adhesive - **Scent:** Unscented - **Specific Uses For Product:** Stain Remover ## Images ![STAR BRITE Ultimate Fiberglass Stain Remover - Easy-to-Use Marine Grade Solution to Eliminate Tough Rust, Leaf & Waterline Stains for Boats and More - Maximum Cleaning Power Gel Spray - Image 1](https://m.media-amazon.com/images/I/61wqOxGdxEL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: How long can the product be used?** A: I was very disappointed with this product.

No hassle. Rust stain just disappeared. ### ⭐⭐⭐⭐ Not a gel, does not work as directed but does work very well in combo with a Magic Eraser *by S***D on May 26, 2024* At first I rated this one star because it will not work as directed on the bottle but will work adding a Magic Eraser. Tried it on a stained fiberglass tub as directed for 2 minutes following with rinse using a shower cleaning brush and the spray from the shower, nothing. Tried as not directed for 15 minutes, nothing. Tried it for an hour, still nothing. It will work if you spray it and let it stand for half an hour to an hour and then respray it and then immediately follow with a magic eraser while the spray is still wet. This modified procedure cleaned all of the stains off of my fiberglass tub and it looks like new. It says use of gloves is recommended and they are right, wear gloves when using the magic eraser. I did not use gloves but absolutely will the next time. ## Frequently Bought Together - STAR BRITE Ultimate Fiberglass Stain Remover - Easy-to-Use Marine Grade Solution to Eliminate Tough Rust, Leaf & Waterline Stains for Boats and More - Maximum Cleaning Power Gel Spray - STAR BRITE Instant Hull Cleaner - 32 Oz Gel Spray - Easily Remove Stains, Scum Lines & Grime on Boat Hulls, Fiberglass, Plastic & Painted Surfaces (096132) - STAR BRITE Ultimate Vinyl Clean - 32 OZ (096232) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/154013871-star-brite-ultimate-fiberglass-stain-remover-easy-to-use-marine](https://www.desertcart.jp/products/154013871-star-brite-ultimate-fiberglass-stain-remover-easy-to-use-marine) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-23*
