    Stain Chemicals

      Stain Away is Terrific
      Stain Away is a terrific product. I have some problems with stain primarily because of extremely hard water. Stain Away does a great job of keeping the sides and bottom of the pool in really nice condition.

      After getting my pool opened and cleaned up, the water was still a weird shade of green, even though it was clear. After some research, I suspected it was excess copper. This got rid of the copper in the water, and the pool is now crystal blue. It didn't get rid of the staining on the stairs, maybe another bottle will?

      Excellent Product
      I had metal stains on my pool's white walk-in steps when I opened my pool in the Spring a few years ago. I just poured a quart of Stain Away in the area of the steps with the pump not circulating and let it work over night. The next day the stains were gone. Since then I add a quart to my 25,000 gallon pool every fall when I close and quart each spring when I open my pool. I haven't had stained steps since.

      Works great for fiberglass pool!
      I've been battling tan metal stains in my pool for the last couple years. The ascorbic acid treatments were getting expensive, and were not a preventative either. This is both a stain treatment and preventative. I tried it out the other day just for comparison, and was amazed that the tan stains were completely gone the next day! It was much more effortless than the ascorbic acid, plus no need to rebalance the pool either. Just pour it into a bucket of water to dilute, pour the mixture around ... read more the edge of the pool, and done! I know that the tea-colored/tan stains cause fiberglass pool owners to go nuts, so if that's you, definitely give this a try!

      Amazing Results
      We have iron in our well water that caused lots of staining in the pool, on the liner, in the skimmer, on the steps; Super Stain Away removed these right before my eyes! I had used several metal removers over the past 2 years, but, none of them helped to remove the old stains like this product. I turned off the pump and poured a portion into the skimmer (it was stained the worse) allowed it to set for a few minutes and the stains totally disappeared! This was really amazing since we usually had ... read more to go through ascorbic acid treatments to get anywhere near this much stain removed. After the water circulated for about 30 mins, the stains on the liner were going away too. This is so simple to use. Thanks so much Intheswim, I can always count on your products.

      Super Stain Away
      I had a huge stain, it was on exactly half of my pool, didn't know why but it was a line down the middle of the pool. Bought this stain away about a month ago used it once and it lightened the stain, so I bought another and used it and the stain was gone. I highly recommend this product.

      For sure Magic stuff!
      I bought this product because we have a lot of iron in our water and I did not realize the affects that has on a pool. I did not know the brand just picked it out. First of all it was priced well based on my search and it worked within a few days the difference was amazing. We converted to a salt water pool - above ground and with the use of this product our pool is the clearest it has ever been. About to re-order for maintenance use now. very pleased.

      Good product
      We started out using Metal Magic which did a fare job. Then we went to the Jacks Magic The Blue Stuff and it did great, pool was crystal clear, we really liked it. Last month I went to order more of The Jacks Magic The blue Stuff and ordered Jacks Magic The Sapphire and it has done a great job as well. We feel that both of the Jacks Magic products are top notch but on a personal level I prefer the Jacks Magic The Blue Stuff so I ordered two more quarts. Outstanding product

      It's crystal clear which clarifier is the best
      I spent less on clarifiers, but this one is worth it's weight in gold. It works like a gem (Sapphire). Water temperature and/or water ph doesn't seem to affect the workability of this product. Hands down the best clarifier.

      Easy to use shock
      Helps keep the pool clean and sanitary. I mix it with water in a bucket briefly before throwing it into the pool.

      Works in toilets too
      I actually dropped this in my toilet tank to decrease the rust staining in the toilet bowl. It worked really well. But you have to remove the rust stains in the bowl first. It doesn't remove the stains but the iron in your water

      It worked!
      I had iron stains on my pool liner from using well water. My first attempt to get rid of the stains worked but then they came back in a couple days. My second attempt included using the CULator and the stains did not come back! I am so relieved to be done with that problem.

      Worked great !!
      We bought this item in hopes to lower our copper levels. And to our surprise it has worked great leap . We put in the 4.0 Culater in the main pump drain, as well as a 1.0 in both our side drains. We had the water tested two days ago and are copper levels went from 0.2. To 0. For the past seven years I have always had high copper levels and now I don’t. I will always have these on hand there’s supposed to be good for 30 days I think

      Fantastic
      Bought this 7 weeks ago and has made the pool sparkling clear and easy to manage. I still vacuum the pool every week but have not had to add chemicals at all. Love this

      Great product it does a lot and you do not need any other products but company needs to do something about shipping and or handling it is really ridiculous

      It worked on my fiberglass pool!
      So far so good, I get horrible mineral stains (probably copper) in my pool and have tried many products, some that involve "Sequestering the minerals" but it always seems to come back and often all at once in a big splotch. This product seems to have worked just fine, what a difference. Love my fiberglass pool, don't even need algaecide and very low chemical cost.. I think I found my stain remover of the future, if I ever need it again.

      Fabulous Stain Remover
      The product works wonders on those "iced tea" stains which can plague fiberglass pool surfaces. Begin the year with a bottle and add small maintenance doses throughout the season to keep the fiber surface clear, clean and without stains.

      Battled fiberglass pool wall mineral stains.....
      Tried Culators, Metal Free, ITS Stain Free, Stain Away powders, etc. then saw a Jacks Blue Magic customer post of similar returning *severe rust-colored* wall stains after few days, mine when chlorination for years and on well water in fiberglass pool. Locals and Internet instructed full pool water drain at $1400 too expensive. So after 2.5 bottles of Jacks Blue magic & BULK citric acid powder combo water & walls clear. Regular treatments of Jacks Blue Magic and light chlorination with ... read more chlorine tabs seem to be effective and persist for a couple weeks now, hope it continues. Be careful fiberglass pool owners use only algaecide 60 plus (no copper), avoid RV antifreeze for line winterization (use legitimate pool antifreeze) due to chemical residue buildup that causes high chlorine consumption and manufacturer says will not subside concentration, and any other copper/mineral products. Will continue to use Jacks Blue Magic as it is only product along with bulk citric acid that has longer lasting stain removal...so far. Citric acid is active ingredient in most anti-stain cleaning powders. Trying small amounts of liquid chlorine now only when needed, hope it doesn't cause re-staining.

      Best product I’ve ever purchased for our pool!
      We got some yellow staining in our pool. Our local pool store told us to shock our pool as a first step. That didn’t work, we then brought in a sample every few days over the course of a month. They had me try using a chlorine tab and rubbing it on the staining (which was difficult since it was at the bottom of the deep end). They said if it rubbed away with that it would be organic staining, that didn’t work. So then I bought some very expensive metal remover and sparkle up for after for the ... read more filter. That didn’t work. Then they had me try an Algaecide remover. More $$. That didn’t work. I started googling and came across the A+ stain remover bought two bottles and the next day it was gone! So happy with this product.

      Wow!!!
      When we opened our pool this summer put the shock in got the water clear we noticed horrible organic stains from leaves, etc on the entire liner floor. I purchased only one bottle of the A+ to test. As soon as i put it in the water the stains vanished! My husband and i couldn’t believe it...saw results in minutes. I have an inground vinyl pool. Do not hesistate. Make sure your chlorine levels are low before hand :)

      OMG!
      After reading the other reviews, I thought, "yeah, sure!", but they are true and so is my review. I have a 30000+ gallon pool so I had to buy three of the product - "ka-ching", but it was WELL worth it. I swear, after half an hour, all of the stains were gone, and my pool was badly stained. It looks like I had new vinyl installed. Truly unbelievable.

    In The Swim Knowledge Pool: Stain Chemicals

    In The Swim's Dr. Pool

    More About Pool Stain Chemicals

    Pool stain chemicals are an integral part of keeping your pool looking clean, new and inviting. Keeping your pool water balanced and keeping a clean pool sometimes are not enough. In addition to our In The Swim stain chemicals, we also carry Aqua Pills, Jack's Magic, Natural Chemistry, and Sea-Klear pool stain chemicals. There are two types of pool stain chemicals - stain removers and stain preventers, and some that do a little of both. 


    Pool Stain Removers

    With balanced chemistry and a clean pool, stain removers are sprinkled over the surface to lift pool stains. For general purpose organic stains, try E-Z stain remover and for metallic stains try A Plus stain remover. You can also make a Stain Sock by pouring one of our stain removers, or pH Decreaser into a thin sock or hosiery, tied off tightly. Place directly over the stain, moving the location every few minutes, in the pool or with your pool brush. Finally a use for those orphan socks! 


    Pool Stain Preventers

    Commonly called Stain & Scale chemicals, this group of pool stain chemicals is used to keep minerals and metals dissolved in solution. Known in the trade as sequestering agents, they chemically lock-up metals and minerals, so they cannot come out of solution to stain your pool surfaces. Pool stain prevention chemicals include products like Super Stain Away and SeaKlear Metal Klear. Use weekly to prevent pool stains from iron, calcium and copper, by keeping these metals and minerals safely dissolved. 


    Pool Metal Removers

    Sequestering agents don't actually remove metals from the water, they simply keep them dissolved in solution, as long as you add regular maintenance doses. However, major chemical movements or poor water chemistry can force metals and minerals out of solution, where they can stain or cloud the pool water. In such cases, an effective DE or Cartridge filter can remove suspended minerals and metals. One chemical however, CuLator Metal Eliminator and Stain Preventer actually REMOVES metals from your pool water. Place the packet in the cage and drop it in your skimmer basket - absorbs copper, iron, manganese, nickel and cobalt ions.
