Yep. I'm pretty sure it doesn't work as well as this Rustyco stuff. I might do a comparison test to check though.
It is taking one heck of a long time. So far after about 24 hours, 3 of the 4 roof vents sliding openers are now working again. Number four is still being stubborn.
I realise now it isn't a smart move scrubbing the rust off the parts in the bath of fluid. It is best to do it outside of the bath - wash - and then put back in so you don't end up with so much sludge in the bottom of the bath => I want the solution to be working on the parts not the flakes of rust I rub off.
I spent some time filtering out the muck and rust
I ended up filtering the last of the solution through a coffee filter - but this is way too slow to do 8 litres (hence the yellow duster used for most of the solution)
