Age doesn't really matter, as long as the pool is gunite or concrete. But never acid wash a fiberglass pool, or a fiberglass lining in a gunite or concrete pool. I suppose I should explain why, because so few pool pro's understand fiberglass, you will probably receive considerable conflicting information.
The finish coat on all fiberglass pools manufactured in a factory is swimming pool gel coat. Unfortunately, this is not true of all fiberglass linings in gunite and concrete pools, although it should be. Gel coat is non-porous which is why it's such a fantastic finish, at least for the first 18-20 years, after which it becomes porous and must be removed and replaced.
Using muriatic acid on non-porous gel coat will cause it to become porous, at which time it becomes worthless, and must be removed then replaced with new gel coat. Once it's replaced, you're good for another 18-20 years, unless muriatic acid is again used. -Bill

Is there a reason that after Hurricane Ike and the removal of the debris from the pool plaster has now become pitted and stained?

That depends on a thousand and one things. Have the pool inspected by a good qualified pool tech.
How can you get rid of brownish green and dark stains on wall have treated the pool for copper but it hasn't worked how can you get the stains off without emptying the pool marbelite pool?
If the stains are more than a few hours old you will have to drain the pool to do an acid wash. Another alternative is to do what is called in the industry a "no-dran" acid wash - and yes the spelling is correct there because it is the manufacurer's way to spell it. The product is put out by United Chemical Co in California. Possibly in Simi Valley. Can be found in most major pool stores at times. You must follow all the instructions on the container or it will not work properly. You also must know when to stop the process. It is best for a professional to do this type of work. If trained properly he will know when to react to the different chemical situations that are involved.
Our pool is 30 years old we have it emptied and patching it because of cracks and wear My husband wants to pressure wash it is that safe to the frail surface?
Nope. It will destroy the poor little pool.
Do you have to sandblast paint off a gunite pool in order to repaint?
Yes. Plaster will not stick to paint. You must sandblast off all the old paint plus any loose plaster under the paint. Surface preperation is the key to any good paint or plaster job. Bill Soukup President Commercial Pool & Spa Supplies Inc.
Does pool acid have an expiration?
While I've never heard of an official expiration date, it does lose strength over time. You can usually tell old acid by it being more yellow in color instead of clear. I've never had it do any harm by using old acid, but it did take a bit more than if it was fresh.
How do you clean the ring around a fiberglass pool?
A good way to clean the ring around a peble tech pool I have aways found. is to get some hydrocchloric acid and an old brush and paint acid over the bathtub ring at the surface of the pool. then rinse it of with a hose. Works like a treat. take care however acid is dangerous stuff avoid breathing the fumes and dont get it in your eyes or too much of it on your skinn. if you do clean it of with copious amounts of water.
Can you wash old dollar bills?
You can wash old dollar bills, but if you still want to use them, then don't. (Trust me I have tried before ;D) -Nahno:-) Alternate answer: Dollar bills are put through the washer by accident quite often but if you still want to be able to use the money I would not recommend trying to wash it. Unfortunately washing old, dirty paper money does not make it new again.

What is the difference between old and new aspirin?
When aspirin gets old, it begins to decompose and you get a vinegar smell. If you smell that, the aspirin is decomposing and acetic acid is being released. Aspirin should be used before the decomposition occurs. It will still work, because the salicylic acid that does the work is still there. It can be corrosive to the stomach and that's why they combine it with a process that produces acetylsalicylic acid (aspirin). When decomposition occurs, you get salicylic acid and acetic acid.
