Gunk
Price: £5.49 Pack size: One litre
As with our top two, Gunk left an oil-free finish. But it was not as consistent as the Comma and Jizer degreasers, as there were patches of grime remaining. Worked best when we left it to soak for the necessary 10 minutes, unlike other formulae, which were more effective when they were brushed off as well.
