What to use to clean LINER, not “clean” the water

[RadarContact1]

Internet searches keep bringing me to barley straw and bacteria... lol

I want to clean my LINER surface so I can apply a waterproofing to my newly installed bulkheads.
Apparently DAWN is safe for ducks but not for fish!

Anyone know of a safe product to prep my liner?

Thanks so much,

I used rubbing alcahol and then peroxide and it did not harm anything

I feel like we used alcohol wipes when we had to patch a piece of liner.

Use vinegar in the aquarium world , not sure if it would be safe to use on pond liner.

I have used peroxide and alcohol to clean liner when I have had to work on it.

Well, excellent responses!

So, I’m going to use a rubber sealer (Flex Seal Liquid)... should I use alcohol or peroxide? Or both? If so is one used before the other?

*I have also used alcohol prior to using a patch before with no issues.

use just alcohol .I used peroxide just on one of the the filter liners because I had no alcohol

When I built my pond, I used lacquer thinner to clean the seams. It evaporates quickly, and leaves no residue. (it's what I had on hand)
