Bilt-Hamber Surfex HD

Water-based Bilt-Hamber’s Surfex HD has a lot going for it – not only is it biodegradable, it’s also one of the cheapest degreasers we tested. Yet while it did the job, it wasn’t quite as capable as our podium finishers. We had to give it a little help with a brush; when simply applied and rinsed, it left behind a thin film of oil.
