If your pool filter is up and running, also it is best to clean the walls and floor if you have a normal to high chlorine level because this will be also your cleaning agent. Take a soft bristle brush, get in the pool and start cleaning, all the above should come off. it is better if the filter is running so you can vac out the dirt, when the dirt goes to the bottom of the pool.
Green stains (copper color) that cannot be removed indicate you might have a pH problem. K
This must be an algaecide of some sort possible a low grade of chlorine. Did you follow the instructions EXACTLY? Is this product supposed to settle on algae spots? If not , did you brush it to keep it from clumping and settling on the bottom of the pool? The black stains, possible caused by the product burning the plaster where it settled --- improper use of product. Impossible to know without seeing the stains and finding out just how you used the product. Contact Bioguard for further info.
My experience is that the stains will go away by themselves, through the effects of the chlorination of the water. Does not matter if the pool is a salt pool or fresh water pool. If the pool has a plaster finish, brushing the stains with a wire pool brush will speed up the process.
Scientist use the stains because the microscopic organisms are very difficult to see without them.
Usually this is the result of converting copper sulfate stains (turquoise) to cupric oxide (grey-black) by oxidation from the shock (calcium hypochlorite) sitting directly on the copper stains. Avoid this by shocking with liquid chlorine or pre-dissolving the granular shock so it doesn't sit right on the plaster. Often the grey-black stains can be reconstituted to turquoise sulfate by letting alum (aluminum sulfate) sit on the same spot. This has to be done relatively soon, though, before calcification covers the stains with a layer of carbonate that the alum can't soak through...
My mobile home park is going through this right now, so I will give you what I have learned. A word of caution, I am still trying to find an unbiased answer myself all of my pros/cons come from the fiberglass or plaster contractors so of course they believe their product is better. From our pool maintenance company (the one unbiased answer I have) They recommend using fiberglass on our Spa to reduce the chance of black algae, and plaster on the pool for the ease of maintenance. >>Pro's for plaster. Underwater epoxy repairs can be made without draining the pool. More resilient than the Gel-Coat of the fiberglass. More readily available contractors. >>Pro's for fiberglass. Resists Black Algae. Resists rust stains from behind. Lasts longer than plaster. ---Con's for plaster. If Black Algae starts its roots go through the pourous plaster and embed in the gunite, and will always return. Plaster doesn't bond well to old plaster. ---Con's for fiberglass. Fiberglass companies go out of business because their products fail in a few years. Fiberglass contractors are hard to find. The only way to repair fiberglass is to drain the pool and apply a new Gel-Coat over the entire surface. Fiberglass is not waterproof at all, only the Gel-Coat is. A Plaster contractor said... "I have heard that the fiberglass fails in like 5 years and then the company goes out of business." A Fiberglass contractor said... "I have heard of huge sections of the plaster falling off, because the old layer of plaster was not completely removed and when it came off it took the new plaster with it, in court the contractor's stance was that their coat held on fine and that it was not their fault since their work was still sticking to the old plaster." I wish a neurtral party like a university would do a study on this. -signed Just as lost in the sauce as the original poster.
First You have to determine what caused the stains and try to prevent duplicating the situation once the cleaning process has been completed.There are two directions you can take toward getting the plaster to a near new state. You will most likely never achieve the same look that the original plaster had when it was installed. Some stains will remain with the most diligent of processes. Both methods include muriatic acid. The methods differ in the way in which they are applied.Neither one of these methods should be attempted by a novice - - no previous experience.One direction you could pursue would be the older and time tested method of acid washing a plaster pool would involve draining the pool then with the proper safety precautions, equipment and tools, start the process of the actual acid wash with a diluted solution of muriatic acid and water. This method may take from a few hours to two days to totally complete.The alternative method involves a totally different and unique method called a "No Dran" ( no drain acid wash). This method works by first disabling the pump - insuring that the pump will not start during the whole procedure. There are a certain amount of other steps to be taken to do the "No Dran" properly. Depending upon size of the pool or amount of water - muriatic acid is added to the pool water in proper quantities so as to bring the total alkalinity to zero. Background experience is a major step in knowing how to start, how to aid the process during the procedure and ultimately knowing when to stop the process. This method will take from about four days to two weeks to complete depending on how severe the plaster conditions. This method could also include draining the pool after the "No Dran" is finished. This is to ensure that all or most of the minerals that caused the stains are removed - because they would now be in suspension in the water - and will not be re-deposited on the plaster a month or two down the road. This method has proved successful in pools with colored plaster.With each method, after completion, there is the start up procedure to be completed.k
I have rust stains in my kitchen sink. What tools or products are available for cleaning rust from sinks without scratching them?
I need help with cleaning sinks that are porcelain. I have a porcelain kitchen sink that is stained. How can I remove the stains without scratching the porcelain?
The filter has nothing to do with the rust stains. You can remove small rust stains from a plaster surface with a small amount of diluted muratic acid. There is a tool specifically for this task which will make it easier to get the acid to the stain. The tool can be found in some pool supply stores. Ken
Shout removes stains from jam, grass stains, coffee stains, ink stains, blood stains, motor oil stains, etc.
Let all the water out. Use any type of baking soda and scrub the walls. Then, remove the baking soda by washing down the walls with water.
To clean and remove stains from a wicker rug, try patting it with a damp cloth. You can also hose it down without using soap.
One of the most effective ways to safely clean coffee stains from partial dentures without bleaching or scracthing them, are denture cleaning tablets.
Grass stains or food stains.
Stains can help you differentiate cellular content. without a stain, it's hard to tell the difference between some of the structures of a cell.
When observing cells under a microscope it is usually very difficult to observe cells and sub-cellular features without stains. Negative stains are background stains that are typically used to provide contrast for visualization when the primary sample cannot be stained.
I had the same problem and finally think I have found the cause. I was using a detergent with bleach. I switched back to a detergent without bleach and the stains went away. Just to test my theory, I did a load of whites using the detergent with bleach and the stains reappeared. I can use the plain detergent and add liquid bleach without seeing any stains, so it must be something in how they produce the detergent with bleach that is causing these problems. Hope this helps!
Soak in cold water.
as soul of one's is pure and without stains like Mumtaj Mahal buried in it.
Depends what the stain is from. NO way to answer this without that fact.
Cells are mostly as transparent as water. Their structures are difficult to distinguish without using stains to selectively enhance those structures and membranes.
For marcite or plaster finish - Acid Wash. Google "acid wash" . Also Pumice stone will srub off black or green algae.
