products for cleaning heat exchanger

It's that time of year again.

I've been avoiding it but its time to clear out the gumph in the heat exchanger

Watching a few youtube videos the Americans seem to use a product called salt away or something that destroys all the crud.

What products are available in the UK or which would people recommend?

Brick acid contains pretty much the same ingredients as rydlyme look up the msds sheet for it and it gives you the acid percentage.
About 1/10th the price of rydlyme

This is the one I use but its very strong only use it outside with a mask cos it realy takes your breath away
But a few mins with this in your heat exchanger and the brass and copper is like new
Looks like the jewsons one is 10% acid and the bq one less than 5%
The link i posted is 36%

I've used RydLyme on various VP heat exchangers for many years now, always done the job well and got me back to correct running temps, so I can recommend it.

Just remember to remove the engine anodes first as it will eat them.
