Apparently the motorhome cleaner's weapon of choice, I can't think of a more talked about (and recommended) product for campers. I've seen it recommended for cleaning roofs, black streak removal, all over cleaning, polishing, sealant renovation, bug removal, wheel cleaner, the list goes on... It only costs a Pound too - what could possibly go wrong ? I would imagine that it's extremely good at removing dirt (and everything else ?) from a motorhome. After all, it's a degreaser and full of acid too. I've used it with great success for cleaning the BBQ, it's great for removing grime from a bicycle, I've even tried it on some alloy wheels (quick spray, brush, rinse, like all good wheel cleaners) I'm not a chemist so don't know all the inns and outs of it all but am damned sure that Elbow Grease isn't coming anywhere near my moho's bodywork... I wouldn't wash the van with Fairy Liquid, so why the hell would I use Elbow Grease ?? Am I mistaken, is it really that good or are the masses unwittingly damaging their vans ?
