Cheapest place to buy RYDLME

Get a boat with outdrives, go on, you know you want to. :D
Must confess do get a bit nostalgic for sitting on the dockside in puddle of hydraulic fluid and emulsified gearbox oil desperately trying to get the U/J to line up with the jackshaft while smothered in greasy crap and scratched to buggery with barnycules,watching everyone else go boating.
The good olde days. :):):)
 
They're really close to me so I just go and fetch it, but thats not much help to you!! I thought it was basically the same as fernox??

Just been on website to see if they have any stockists local to me.Would appear its got to come by post.
Wondering now,wether to just get some B & Q brick cleaner.

Fernox DS-3 descaler is based on sulfamic acid

Rydlyme is based on hydrochloric acid

Some brick cleaners are hydrochloric acid solutions
 
Descale ... Update.

Rigged up pump system with raw water/impellor pump bypassed with 200cms of copper tube between inlet and outlet hoses.
Old diesel transfer pump used to pump 5L of Dynamic Descaler through gearbox oil and engine heat exchanger reverse flow for 2 hours (ish).
Some rather funny looking sludge emerged but no lumps.
Out in morning to see if temp reduced. !
