How do I clean pond liner?

Question

I have just emptied my pond, it is 11' x 11' x 5' deep and the pond liner has a white dried on residue on it. Is there anything apart from a pressure washer and a brush I can use to clean the liner so that it is black again (any cleaning solution that is safe, I don't want to kill my fish when I put them back in)?

No I am not Tim, I am just a huge fan of ISIRTA, ISIHAC and especially The Goodies, and in case you wondered I am a woman. Thank you, you really made me laugh.

Thank you for your answer, but the residue I need to get rid of can not be removed by using a pond vac, I know this because I already have one, as I said I am looking for some kind of solution to use as the residue is dried on.

Okay Nikgy71 where do I buy elbow grease from , ha, ha ha :-)

Answer 1

Bill would know coz he's a nature nut
Graham would know coz he's a clever $hit
So you must be Tim. Hi. Love ISIHAC - keep up the good work.

Answer 2

The only safe thing to do is buy a cleaner made for aquarium and pond use, or to use white vinegar. Both will require lots of rinsing. I would just stick to using a pond-vac if you can. Hagen makes a great one with a brush attached.

Answer 3

Mix one-gallon muratic acid to four gallons of water.
Briskly scrub all surfaces of the pond with this solution using a brush or broom.
This will not harm the pond.
Mix more solution if needed being sure to reach all surfaces. Rinse the pond thoroughly, drain and refill.
Your pond is now ready for fish and plants.

Answer 4

You could have used a pond vac. It's a bit like a vaccum cleaner. you stick it in the pond and hoover the dirt up. The main advantage is that you don't have th empty the pond and they are fairly cheap at around £60-100.

Answer 5

I would try SALT. Most fish can tolerate a small amount of salt in their water, and it might make a good scrubbing solution ??

Answer 6

preasure washer or some elbow grease,would,nt use chemicals.ive done it that way for years but be careful you dont split the liner.
