Cleaning underside of Endless Pool cover?

[kimalex]

Hi friends,

I am a relatively new owner of an outdoor Endless Pool. I noticed there are some mildew spots on the underside of the vinyl cover. I tried cleaning these while in the pool using baking soda paste and a toothbrush, with some success. Any other suggestions for how to clean the underside of a rollup vinyl pool cover, preferably without having to remove it? Thank you!

A brush with a mild liquid detergent solution may work. The detergent may get some foaming in your pool water for a while. The brushing is important. But it will be a never ending project as the mildew will grow back if you have the right environment in your pool.

Thank you for the suggestion, Allen! I will soon be changing out my water so this may be a good cleaning step to take before doing so.

@ajw22 please advise my usual mold/mildew killers in regards to Kim. For mold and mildew In the non pool world, a 25% mix of either bleach or white vinegar in water is the common cleaner. Using a spray bottle would keep most of the solution on the canvas/cover and most of the mildew and cleaner would wipe off with a sponge.

In theory, a couple of ounces of bleach would only raise the FC a hair *or* a couple of ounces of vinegar would lower the PH a hair.

Either of those would be fine for this use with a spray and sponge application, correct ? Or am I missing something ?

Any dead mold/mildew that dropped would get picked up by the filter.

Have you tried spraying the spots with diluted bleach solution? Baking soda isn't a mildew killer, all the brushing will disrupt it but it isn't gone until its killed and gone.

@YippeeSkippy, what about the white vinegar solution also ? Its not a normal TFP acid, and much weaker than MA, but in this rare instance it wouldnt cause any harm either, right ? 4800 gallons should eat a few ounces of it without much noticable chemistry change.

Worth a try.. I have no experience with using vinegar on mildew but if it works, yay!

I only know of bleach killing mildew.

It does. I Just double checked on wiki-how. Bleach, white or apple vineger, baking soda mixed with vinegar, borax, and ammonia. Ammonia is bad obviously. Some people have the borax on hand so that was a happy suprise. The more i think about it, the vinegar would probably leave an odor behind. So spray bleach (pure with no additives /colormax) is probably the best bet.
