Vanish Pool & Spa Stain Remover (2LBS)- Natural Safe Citrus Based, Works Excellent on Vinyl, Fiberglass, and Metals, Removes Rust and Other Tough Stains

My saltwater gunite (cement) pool had several areas of stain. They were brownish orangish in color which I took as iron stains. I dispensed this product as recommended. The whole 2 lb. container. Within 6 hours there was a noticeable difference. Within 24 hours was a satisfactory result. After 48 hours….NO STAINS! By any standard, Price, Ease of use and non toxicity this is a superior product. Everything I’d read prior to purchase seemed to suggest in worked well with liners. We’ll, it works well with cement.

Best product ever. I almost gave up on my pool because of stains all over the pool floor. I tried few different products and nothing worked. It was very sad that I have to empty the pool in the summer. Once I found this product in the Amazon, checked reviews and ordered it. This product is magic. I dumped whole container in the pool and ran filter for 8 hours. Result was amazing. Since my pool had so many brown color and some other color stain, 85 % pool stain gone and water start looking good and water was good enough clean to go in the pool to enjoy. I ordered one more container and dumped in half contain to make water crystals clear. Again this product worked, it is the best product, no side effect at all. I ran the pool for 6 hours this time and result was fantastic. My pool water is crystal clear now. I saved half container for future use. I feel like without this product I would not have pool or maybe I have to hire pricey pool professionals to figure out why I am getting all kinds of stains. This product works excellent and recommended for any stains remover.

This product worked amazingly!!!! It took 8 days after applying the stain remover and I wasn’t hopeful at first but WOW! Every single rust stain is gone ! There was widespread rust stains from granular fertilizer that accidentally got blowed into our pool. Someone recommended this product to me and I am behind thrilled at the results ! Just be patient it will work.

I tend to be skeptical of many claims of amazing results from any product, but that's exactly it - I am amazed! We have a large pool with a vinyl liner. After replacing the sand in the filter a few weeks ago, (an aside: sand quality certainly varies between sellers!) we noticed the liner was increasingly becoming stained all over with an ugly brown. Vacuuming and brushing didn't help, so I figured, "What the heck, I'll give this a shot." First, I completely cleaned and vacuumed the pool, and backwashed the pump thoroughly. The label directions state that you need to balance the pH to a neutral point, which I did to ensure the product had the optimal working environment. I put the product in on Monday afternoon, and by Tuesday afternoon the stains were completely gone, and the pool looks fantastic! I wish I'd taken a "before" picture but, like I said, I didn't expect much. I have no problem recommending this Bosh product, 100%, and will be keeping it in my Amazon shopping list.

I had my liner folded up all winter and when I put up my above ground Bestway pool the liner had stains. I bought this product based on the reviews and citrus based. It worked wonderful. I followed the can directions. Sprinkle and let it sit on bottom of pool for an hour, then brush some, then turn on pump filter. It says 24 to 48 hrs to see full results. After 12 hours I saw a big difference but a few light stains left. I turned off pump some of the times to let it settle then back on again. After 24 hours most of all the stains were gone like magic. ha - I have a couple very small patches that I am giving 48 hours but basically my pool is clear! Wonderful product! ​ Speed: Works fast within 24 hrs.

I have well water that is very high in iron. As such, I have a generally even orange-red stain all over my vinyl in-ground pool, with some very bad spot here and there. I followed the instructions, cleaning the pool and correcting the PH level before spreading the product throughout the pool. There was immediate impact in areas where I had a higher concentration of the product. That kind of made things look worse, as I know had spots showing me how bad the stains were. I waited a day, then two, then three days to see if there would be an impact, and was disappointed to see no noticeable change beyond the spots that had been immediately cleaned up. I began researching other products. About a week after application, I woke up one morning, looked out the window, and the pool was spotless. It looked brand new. The only reason I didn't give it five stars is because it never mentioned it could take as long as it did to have an effect. I'm planning on getting a pool magnet to see I that will help keep my pool pretty for long term.

I used the entire can for my 14,000 gallon salt water pool, it took a few days but it did seem to lighten up the staining, not completely gone though, hope it won't return, time will tell, only been just over a week since I put it in my pool, I poured it in and let sit day 1, then put pool on recirculation only for next 2 days and brushed walls 3-4 times a day, then put it back on filter on 4th day, stain were definitely lighter but not completely gone

Great stain remover!! Ordered several times
