FSR Davis Fiberglass Stain Remover , 2 Liters - 792

I have been using this product for years! I keep my boat at the lake for 5 months and this product keeps my boat shiny. I just wipe it on and wipe it off. No scrubbing ! Easy to use

Bought the large size bottle because we use this very often on our boat. It works well for those stains on fiberglass that just will not come out with regular soap and water. FSR works particularly well on diesel exhaust soot that gets on the boat sides near the exhaust outlet. The large size is an economical alternative to buying the small spray bottles. You will be amazed at how well this removes stains on fiberglass.

It did well getting dirt off but not any stains. I let it set, I diluted it and brushed, I used a drill brush attachment, I tried everything to get the stains out with this. I ended up just using a paste of baking soda and dawn, saturated with vinegar, let it set for about 30 minutes and ta-da!

Easy to order. Quick delivery. Needed a cleaner that will work on shower floor. So far, I find it to clean and shine the shower floor.Thanks

Works incredibly well. Used it on a fiberglass shower/bath tub that is only 7 years old but had black stains and discoloration that wouldn’t scrub out with bleach or anything. Applied this product on whole tub, let it sit for about an hour, and then scrubbed/wiped it off. Tub looks brand new. I wish I had taken a “before” picture to share.

This product is definitely worth the money. I had rust stains all over the boat deck due to a project where we were cutting galvanized steel. This product was the only thing that worked to remove the stains and it even loosened any small particles of debris on the deck so I could safely scrape them away. I love this product!

I've been using this product for years and it's always done a great job removing stains with a little work involved.

Works amazing

Used it in my shower amazing results . Used every product on the market and nothing worked but this did !!

I had a friend tell me about this stuff, he brought his over to show me on my boat how well it works. I bought my own because no scrubbing is needed with this stuff, just wipe it on and off and your done. It REALLY is that good.

This does not work, saw reviews saying it worked amazing on old fiberglass showers it did absolutely nothing to mine. I've had better results with Mr clean magic erasers. It also stained my tub blue from dripping down the shower walls. It's horrible to apply, has a super weird (although not strong) smell.Do not recommend for fiberglass shower.

Everything about this product worked we used it on our pool steps, we did some renovation to the concrete deck and metal got into the pool causing rust spots which I panicked we tried the vitamin c (absorbic acid) and it didn't work. This was so easy leave on for 5 minutes and wipe off! What a great product! 100% recommend

the stuff works great on my boat
