Always such helpful information at Hallmark Pool Supplies. I was just noticing the water line on our pool is starting to need a clean. I had no idea there was a special vinyl cleaner. Thank you Mark for your well done videos.

I have an above ground pool and I use a soft car wash brush. It does the job very well and there is no danger of damaging the liner with it.

I have a in-ground vinyl liner pool and collected all your videos. They are all spot on and as a DIY saves me money. The Pool Surface Cleaner I was not aware of this product and will start next pool season. Thank you for all this great information and demonstration.

Liked and subscribed. First time Pool owner, above ground 12’ x 24’. I have a lot to learn.

Draining your vinyl lined pool is a set up for trouble. Believe this; one of my kids poked a hole in the bottom of our above ground pool years ago. The guy at Lesl** Pool supply sold me on a patch product, but instructed me to “drain the pool for best results”. Not knowing any different, I did just that. Patch complete and let it set up till the next day and refill. About 2/3 full, the liner pulled away. I blamed the kids for getting in and climbing out with their feet against the sides. Drain again and repeat. Yep, liner separated from the top deck channel again. Went back to the pool supply and asked the same counter person why this was happening. Once he discovered his error on instructing me, he forked over a new $130 liner. This was in 1988.

Very helpful. Thanks Mark !

Good info! Just moved into a house with an above ground pool. Opened it this summer and the water is clear but the liner seems to be stained, giving the water a light green tint. I tried using a magic eraser on a small section which took the green off but wasn’t sure if this was safe for the vinyl.

Good stuff! Thanks!

Great information, appreciate it very much

Thank you for sharing all of this very valuable information. New subscriber.

Thanks for this video. The cleaning part was huge for me! About 5 years after my mom passed, the liner just died in those areas where sun beats on it and I wasn't diligent about cleaning but she did!

THANKS GREAT INFORMATION MANY BLESSINGS ❤❤❤

All your videos are excellent very detailed and understandable. What we should we if chlorine feeder started overflowing?

Nice service

I uae a lightweight sponge mop to "brush down " the sides and bottom. Wirks great.

How avoid a metal rusted blowout ?

Hello Mark just finished watching one of your videos was very impressed I have a question I have an old patch because it still is leaking how do I remove it without damaging

Hi There, thanks for the video. Very interesting around the above water area. I’m in the UK and am in need of the invisible liner replacement patches you noted in this video. Where would I send the picture of my liner to be matched if possible? Thanks Mark

Mine in-ground liner lasted more than 15 years! Replacing it now. It's just a thin layer of plastic; people need to remember that. A three-thousand-dollar one.

Thank you for the info, I am in my second year of owning a brand new 24' above ground pool. In your experience would the dolphin E10 robot poke pin holes in the liner around the cove? Mind you these holes are only on one side of my pool not the whole thing and I do clean 2-3 times a week. Or would a bristle brush left in the sun last summer be the culprit? I am leaning towards the plastic bristle brush when I had an algae issue last summer.

Hi Mark, Great video! We just had a new liner installed in March...my husband and I noticed that our pool is losing water very slowly, but we are having a difficult time located the leak. We think it's a pin hole size. We have an above ground pool. It has a metal circular 24' frame. It looks like water is coming from bottom or down on the bottom side...just not sure...do you have any suggestions of how we can locate the hole? Thanks in advance! Jackie😮

How thick of a liner should be bought AND what would be the life expectancy of a pool liner. I am considering an inground/slightly above ground pool 16 to 18" above. Thankyou!

Do you have an video on how to measure a pool for a new liner?

The one thing he did not mention to prolong the life of your final liner is to not have Shockett added in quantity that it sinks to the bottom and makes contact with your liner. Best to use a fast dissolving shock it and add it very slowly

How do you recommend lifting a sag area of the vinyl liner? Do you recommend a tool to use? Thanks.

Never drain the pool? Does that include Intex above ground pools in harsh winter environments? I've been taking mine down every fall and reassembling in the spring.

Hi Mark, thank you for your video, I have some concrete sealer that is unfortunately stuck to my water line from the concrete company, it’s been 4 years now and I can’t get it off . I was thinking after seeing your video that I could try to buy the vinyl cleaner you were using and attempt that but I’m sure it’s not going to remove the areas of sealer that are bad . I was wondering if you think I could place a patch over the unsightly areas to cover it ? Can you help me match my liner ? If so how do I contact you? Thank you

Hi I just found your video searching for something similar to your waterline cleaning. I have an intex ultra xtr above ground pool and this is the 4th summer. I don’t take it down because it feels like it would damage the liner trying to fold it up and restretch it the following year and I have a friend who said it was to difficult. So there it stays and has been great. But this year I have noticed the liner on the rail seems dry and the cover has put a slight bit of wear on it because as it rubbed against the liner on the rail over the winter months and the weight of the snow you can now start to see the think white threads ever so slightly in some places on the front side where it gets the most wind. So I thought maybe there’s something out there to keep the liner soft that’s not in the water to help it last longer. It would be a shame if the liner fall apart at the rail and it can’t be held up any more. So how do I fix this? You talked about the waterline vinyl cleaner and dry rot. Can this possibly be something I can use on all liner areas outside of the water like the rail and have it help keep it healthier? Also I’m thinking the pool cover is a bad idea now do you have thought in a leaf net through fall and then just leave it uncovered all winter so that there’s no cover rubbing on the liner in the rail ? Thanks for your video and help! Hope to hear from you! Oh BTW I’m in Plymouth Massachusetts if that matters.

I live in canada and was told our winter are not good to leave our above ground pool liner up any thoughts

My mother has a 10 meter tiled pool in Spain , can we liner over the tiles instead of taking tile off , second do you have any idea of what the cost would be ? Just a rough idea so we know when we ask that they are not ripping us off , thanks for your help.

I tried to use a magic eraser on my water line, I only did a section, due to it having a black ring stain around it, some came off but it did discolor some of the liner. I stopped from going any further. What do the black stains come from? Is it metals or scumb?

We have an inground pool that requires a liner. Previous owners pulled the liner, now there is a significant leak into the pool through a crack in the concrete. What is the best method to repair the crack? We have been told it is not necessary, but the water flows in constantly. I want to repair the pool and get it working.

Surface/vinyl cleaner brand recommendation?

Hi I live in Ny. I have a waterfall wall on the side of my pool. The stone has created a serious amount of calcium deposits on the liner. It’s white and very crusty. How can I break this down and clean the liner without damaging it. It is all above the water line where the liner remains dry.

How about cold weather, keep the pool full? It will freeze solid here in the Dakota's

Our vinyl liner has terrible stains around the entire pool because we didn’t open it last year because I was going through cancer treatment and just had no interest. It was a little stained even though I cleaned it, but now it’s awful. Could I use vinyl all around the pool to hide it?

are robotic vacuums safe for vinyl liner pools?

What kind of automatic pool vacuum would you recommend for an inground vinyl liner pool, 3 ft shallow, steep drop, 8 ft deep

I saw the cricket 🦗 swimming

We have a stain in our pool and all videos refer to is metal was root cause, we can’t figure out how that’s possible since we don’t put metal near pool? We’ve tried stain products from our local pool service any suggestions?

Where can I purchase the surface liner cleaner from?

I have been told CALCIUM is a good thing to add to the water to keep the liner "pliable". Any truth to that?

i don't know which chemicals to use on my new liner, have 27 ml liner

The biggest mistake in pool ownership is spending big bucks at a pool store on supplies that can be bought elsewhere for much cheaper. Pool cleaners are just other products rebranded, pool chemicals are mostly the same. If it says it's for your pool it's marked up 1000%.

Salt Water or Chlorine?

Mark, I am a 1st year pool owner. Above ground 28ft pool. I did not use a pool pillow for my pool cover and while attempting to remove the pool cover some of that residual water and leaves got into my clear pool water turning it brown. I’m worried I will not be able to get the water back clear, will that be a issue upon opening my pool up this weekend and cleaning it up? Please help

So just making sure there are only 2 ladder bumpers: male and female right? Because my neighbor told me there are 72 different types of ladder bumpers and some may also be non-binary.
