Descaling Solution

Hi,

I would like to clean the raw water side in my perkins 4.236 engine (heat exchanger is ok) any idea what I can use beside Muriatic Acid?

Will CLR or Citric acid do the job?

Thanks

I also have a couple of 4.236s. I have been doing a spring and fall flush with Salt-Away. Seems to help.

Re: Descaling Solution

I used:
Apex - Rydlyme is the world's leading biodegradable descaler, rydlyme is designedto dissolve water scale, lime deposits & rust deposits, but is not water treatment orwater conditioner.

Re: Descaling Solution

I use a hose with a fitting that replaces the inlet fitting to the raw water filter. A 25 litre pail filled with fresh water, add the small amount of Salt Away. stick the hose in the pail and start the engine. You will see foamy bubbles come out when it has worked through the engine. Shut it down, remove the hose and reconnect the raw water to the strainer. You can leave it like that for a few hours or until next time you need to start your engine. It will just flush out. There is a kit sold that allows you to do this by removing the raw water screen cover and making your connection there. I was too cheap, so I didn't buy it. Kind of depends on how much room you have above your raw water screen. I do this to the twins and the genset.
