tanuki Posted March 18, 2011 Report Share Posted March 18, 2011 I need to clean the crap out of a radiator.....you know all the crap that gets inground and lives inbetween the little fins. anyone know how this can be done, I have tried soaking it and brushing it with a soft toothbrush but even that is damaging the fins. Anyone know how its best done or that can steer me towards someone who can do it for me. Cheers Link to comment Share on other sites More sharing options...
Egg on Leggs Posted March 18, 2011 Report Share Posted March 18, 2011 On a related note (because I need to clean up my rad too) whats the best way of straightening the fins? And for painting the rad? I do seem to remember Frosts doing a radiator comb type of device for theis sort of problem. Link to comment Share on other sites More sharing options...
Bungle Posted March 18, 2011 Report Share Posted March 18, 2011 I have just done the radiator on my RG500. I de-greased it 1st using gunk in a spray tin then hosed it down. I then sprayed through the radiator fins using brake/carb cleaner, which blew out 26yrs of crap nicely with the pressure & dried quickly! I repainted it with smooth black hammerite out of a spray tin. Looks like new!! Link to comment Share on other sites More sharing options...
tanuki Posted March 18, 2011 Author Report Share Posted March 18, 2011 Cool, I'm guessing you didn't spray the fins? Link to comment Share on other sites More sharing options...
Bungle Posted March 18, 2011 Report Share Posted March 18, 2011 Cool, I'm guessing you didn't spray the fins? Yep sprayed the fins, but you have to spray from all directions to make sure you cover every bit. I use the smooth hammerite as it has a rust/corrosion inhibitor & goes on thinly,[ a bit like PJ1 exhaust paint] so does not gloop up the fins.

Mark/Foggy Posted March 18, 2011 Report Share Posted March 18, 2011 If you dig around you can find foaming air-con heat exchanger cleaner. This suff is nicely alkaline so you need to use a lot of water to neutralise it after use, but it works. I work it in with a stiff brush and leave to foam away. I've had a small beach come oot of a rad that had been kindly installed by a certain James Hayden, no need to ask how It realy will shit a lot of heavy particles and not just dirt. This stuff does wonders and neatly etches back the alloy a little to a bright finish. Loverley stuff. I'm thinking that some of the alloy wheel products might do something similar, but I've not tried yet. Link to comment Share on other sites More sharing options...
Mark/Foggy Posted March 18, 2011 Report Share Posted March 18, 2011 I do seem to remember Frosts doing a radiator comb type of device for theis sort of problem. And somewhere in my beaten up memory is the thought that the tool is called a frog in the trade. I've managed to lose the set of specialist pliers that I was once given that did the job perfectly. I mainly use a cable tie nowadays. Link to comment Share on other sites More sharing options...
