Just read http://antjanus.com/blog/thoughts-and-opinions/use-vim/ and found the following lines in his .vimrc at https://github.com/AntJanus/dotfiles/blob/master/.vimrc#L200


" Whitespace fixes
highlight ExtraWhitespace ctermbg=red guibg=red
match ExtraWhitespace /\s\+$/
autocmd BufWinEnter * match ExtraWhitespace /\s\+$/
autocmd InsertEnter * match ExtraWhitespace /\s\+\%#\@<!$/
autocmd InsertLeave * match ExtraWhitespace /\s\+$/
autocmd BufWinLeave * call clearmatches()

" Strips whitespace
nnoremap W :%s/\s\+$//:let @/=''
