  • Fast and easy with no setup
  • Small amount of acid used will not affect pool chemistry
Purity Pool is a family business founded in 1961 by an experienced pool service professional. Since all Purity Pool Products were designed first for professional use, durability and efficiency have always been top priorities. The Out Spot is a self-contained underwater stain remover. The cup holds about a cup of muriatic acid. Once filled and connected to a standard pool maintenance pole, the Out Spot can be lowered down to the pool surface and placed on top of a stain. Since acid is heavier than water, the acid seeps through the pad (slowly diluting, so go for the worst stains first!) over a ...

I had a stain at the bottom of my pool for a few years.

This year we had a few more.

We have well water and I discovered some time ago that ascorbic acid (Vitamin C) works great to remove iron stains on the (old) vinyl liner of our in-ground pool.

The problem was how to get the acid down to the bottom of the pool, especially in the deep end where there were lots of stains.

It's a bit of an exaggeration to say that the liner looks like new, given it's quite old and has some bleached out spots, etc., but compared to the dingy look it had before it is amazing.

Jane's Review: Should I buy this product?

Jane's Review

Yes! I recommend this swimming pool stain remover based on its brand popularity. Let's go over the reasons why buying this swimming pool stain remover now is a good idea, and also things to consider before you decide on this item.

1. Purity Pool is a known swimming pool stain remover brand

Purity Pool doesn't attract too many people on Amazon among other swimming pool stain remover brands. But I found some YouTube videos that talk about this product, which means this is a widely known product/brand. I have attached the videos above and links in the additional research section down below, so don't forget to watch and read those!

One thing to be careful about here is that I'm not verifying if this product's maker is a household name or not. This section is more focused on whether this is proven enough by its consumers, whether people actually love this product.

2. This swimming pool stain remover has okay reviews on the internet

Some people have a great experience with a product, while some are unlucky and get a defected item and have to go through the whole process of returning them. Since people have different experiences about a product due to various reasons, don't read too much into one good or bad review. Reading multiple reviews with different ratings can help you picture how good/bad the product generally is.

This swimming pool stain remover has moderatereviews on the internet, and based on current trends, it's likely that people will like this swimming pool stain remover more a week later. I summarized what fans and haters say about this product above in the good/ok/bad table, so don't forget to read those since they paint the whole picture! And of course, if you want to read more detailed reviews, many of them are on Amazon!See More Reviews on AmazonSee More Reviews on Amazon

3. Take a look at its price history

image/svg+xml Highest Price Lowest Price $59.99 $29.90

Price is one of the most important factors in making a purchase decision. I analyzed the price of this product in four parts: its recent price change, when it was most expensive/cheapest, its price volatility, and a price prediction I made, just in case you want to wait.

First off, let's talk about its recent price change. The price of this product has not changed from May 14, 2020 to May 21, 2020, which means that it has steady and healthy supply!

Next, we need to look at its highest price and lowest price. Historically, the highest price point for this swimming pool stain remover was $59.99, and the lowest price point was $29.90. The current price is greater than it has ever been. If the best price is what you're looking for, this could be potentially be a bad time to purchase.

What about its availability and price volatility? This is another aspect we have to dig into before buying something. I haven't seen this product being unavailable since I started reviewing this product. So as far as the availability goes, this product is solid. If you plan to make a repeat purchase of this kind of item, this is your product! In addition, the price tends to stay more or less the same. Not a lot of price movement is expected, but the price could still move in either direction by a smidge.

Considering all this, will the price go up or down in a week? Based on past price points, I expect the price to be $44.43 a week from now. It might be best to wait for a future price drop, but if this product checks all the boxes for you, don't wait to optimize for small gain.

4. Manufacturer has generally positive reviews on their other products

The maker of a product is another factor you want to definitely consider before you buy anything. What if there is a piece missing or there is some defect in the product? With anything you buy online, there is a small chance of this happening. But don't worry too much, because Amazon has an amazing 30-day refund policy (Amazon❀️). Still, you want to make sure that the manufacturer or the seller has been helpful in resolving this kind of problem and/or has been helpful to its customers about general product inquiries. The manufacturer of this product, Purity Pool, has generally positive reviews on the internet. It's generally a good sign if the manufacturer has good reviews overall. If your purchase decision heavily involves how well they make their products and treat their customers, and if you like this product, I'd go with this product!

5. There are other options you might want to check out
