does anybody have an idea of the best method on how to clean the water marks of a swimming pool roof. does the pool need to be empty before you can access the roof. is there a soloution you should use to remove the marks.

cheers

Pressure washer fed from fresh water, no chemicals. That's what I use above and around my indoor jacuzzi......

Don't use detergent because it will make the pool soapy!

Dont forget, you will need to adjust the pool water pH and Cl / Br afterwards.

If it's really grubby, you could use a swimming pool surface cleaner (for cleaning the surface of the pool... the tiles... not the surface of the water!!) because this is compatible with the pool chemicals.

Maybe WFP would be the perfect answer for a glass roof?

thanks for the reply. the pool is in an gym, so do you think that the water  needs to emptyed. would a water fed pole work? I thought it would best done by hand with use of a scaffold tower, buy maybe i was wrong

Dont panic about emptying the pool.... as long as you dont use chemicals on the roof, any dirt that washes into the swimming pool will be caught by the pool filters, which can then be back-flushed.

Scaffold would be best for a really filthy roof.... you can really scrub a dirty roof, but if it's mainly water marks on the roof, then water should take them off again.

Cover the pool before any work, even indoor pools will have a huge cover laying around somewhere.
