Plaster stains

[lafonte98]

I have some stains in the deep end of my plaster bottoms pool. I have taped sandpaper to a brush I use to normally brush the pool which has helped remove stains in the past. Its just kind of a hassle. Does anyone recommend a brush made for this or had something they have tried that worked good?

Thanks,

Greg

Before attacking stains, it's best to figure out if they are metal stains, organic stains or calcium scale with embedded dirt. Each type of stain has a different approach to it for removal. Mechanical scrubbing only works if it's from a source that will not return; some types of stains recur in the same places because of more fundamental issues.

Have you tried identifying the stains?

They are a light brown/yellowish color and typically show up in the same places. In the deep end where the floor curves up the wall.

I would suggest using some Vitamin C in a sock to determine of they are metal stains. If they don't react (lighten) to that, then you can put a trichlor puck on it for a few minutes to see if it's organic/biological.

I assume I can do all of this under water without draining the pool?

Yes. No draining.

They make a little attachment (like a sponge with a reservoir) that you can put on a pole and put Muratic Acid or Vit C in a cap and then put the spot.

I got one and used it on a few spots. Worked ok.
