I am surrounded by rape fields every year - so my beekeeping has adapted to it.
I do not try and extract the liquid honey as soon as possible, as I always worry there will be a hungry gap.... so I use wireless foundation in my supers and melt the honey off at the end of the season. Our association has a rapeseed honey extractor (a bit like a wax melter just bigger) and it works for me. I steam clean my empty (and usually quite sticky) frames (home made (wallpaper) steamer and old brood box) every winter.
Only drawback is that you need to re-do the frames with foundation every year and if it gets hot before they have drawn them out properly, they tend to sag a bit in the heat, causing the frames to be filled unevenly.
