You can get proper contact cleaner from Toolstation or Screwfix as well as electrical wholesalers. Interestingly, WD40 do a branded one but any labeled contact cleaner will do the job.
If I had a tenner for every bit of electronics I have had to clean over the years that's been given the WD40 treatment, it would make a very useful amount. Would you use washing up liquid in your washing machine, or more relevant, put olive oil in an engine because it's 'all oil'?
