Best power flush fluid?

[Brandnewcombineharvester]

Hi guys!
I've just purchased a power flush pump system.

And would like some advice on what is the best fluid to use for badly clogged systems that have limescale , and where to buy it from.

Thanks in advance guys!

Kemco chemicals work very well I have one of there units its about 15 years old now and still going fine, But found that there own products work good in hard water areas. Parts Centre used to stock them or buy direct
