Blocked spa bath jets.

[Corkem]

Does anybody know of a cleaner which will unblock jets in the bottom of a spa bath. I think limescale is the problem as the water is very hard. I've asked at B & Q and Homebase and they both said Milton sterilizing solution (as in babies bottles). Has anyone had this problem and found the answer?

In the Usa where we had one in the house we rented, we were told to fill the bath and add a generous amount of dishwasher powder (not tabs or liquid, )then run it for 10 mins to deal with this

You need a good descaler like Fernox DS1 (I think) obtainable at plumbers merchants and B&Q. Use with very hot water and allow to fully circulate if possible to get to the other parts. Use a scale inhibiter or softner in the water supply to avoid this problem.
