Miles Laflin: My name's Miles, aka thep00lguy, and today I'm going to show you how to professionally clean a hot tub. All right, this is probably the worst hot tub I've had to work on. There's literally slugs, spiders, the water's black, and the smell is just disgusting. So, the first thing I've done when I got there was taking the cover off for the actual job, which, you had to take the cover off, inspect it, see how bad it was. We took that off and stood it up on the grass, and that got jet washed and brushed down. And there's a lot of creases in the cover, so there's slugs in there as well, still trying to hide and sort of stay in their home, but they all got cleared out. So it was mostly water with the jet wash, and then you had a little bit of cleaning solution. With the cover, that took around an hour to clean. On the side there's a lot of black markings, like slime and dirt, and it's still a lot slugs sort of slithering around. Like, 100 slugs on this hot tub. And, yeah, the guy said he hadn't used it for, like, 10 years. So I just started off with a jet wash, and they sort of got jet washed away at first. There was so many, and to be honest with you, I don't really fancy picking up slugs, so. So, the white tube there, that's connected to my submersible pump, which I'm using to pump water from the hot tub down the drain. So I've got the broom out, 'cause you've got, where you sit down in the hot tub is quite, it's a bit like a bowl, so it'll hold a lot of water, and what I'm just doing is I'm just pushing it into the middle so the submersible pump can drain it out easier. At the bottom of the tub, you just had a little bit of dirty water and a little bit of grit. So, underneath here, you've got the main circulating pump. You've got the heater for the hot tub. All the pump equipment's kept underneath the hot tub. So, I pulled the panel back, which all needed to be cleaned out as well, and I used the Hoover to get all of that. So, a hot-tub flush is a chemical, which you will pour in through where the filters are usually set, and then you turn on all the jets in the hot tub. So, yeah, once you put the hot-tub flush in and it starts reacting with all the fats and anything that's caught up in the tubes, inside the hot tub, it creates a foam, and then you can also see, in the foam, you can see the dirt which is coming out of the pipes as well. So you can see it's working. Once it bubbles up, you can get in there and just net them out so they don't -- 'cause what happens is it'll start sticking to the sides, 'cause it's like an acrylic material. So it will stick to the sides, and if you don't scoop it out, you'll have to then scrub the sides again. So it's just easier just to get in there, net now the foamy bits and all of the dirt on the foam, and it'll make it easier for yourself. So, I've got this hot-tub filter here, and it's looking really black. There's a lot of dirt all over it, and I'm going to give it a rinse down just to clear it so it's filtering properly again. Most pools have sand filters, whereas hot tubs have cartridge filters. So what happens is, obviously, while the filters are collecting the small particles, if you don't take them out and rinse them, your water will start to go cloudy. So it's basically just dirt and then obviously anything that comes off your body, like dead skin. Anything can get caught up in the filter as well. So you can rinse them down with your garden hose, and then you can spray them with filter cleaner, which just disinfects any bacteria that's on them. And then put them straight back into the hot tub, and then they're ready to go again. On hot tubs you can get a little floating dispenser, and it just floats around on the water, just slowly releasing chlorine or bromine. There's also a chemical test kit, and on the left will be to test for the bromine or chlorine level, and on the right I am testing for the pH level. You're looking for the middle color, which is around 7.2. So, with the hot tub, it was looking, after I'd finished with it, it was looking brand new, nice and blue again. The customer's really happy with it, and it just looked like a new hot tub rather than what it did, like, five hours ago. That was definitely the worst hot tub I've ever worked on, and actually seeing the final product with nice and blue water in it again, nice and clear, and everything working on there, I was pretty happy with that.
