THERE’S something old school about Hyper Clean, from the plain packaging to the solvent whiff. If you want to spray it on you’ll need to find a trigger bottle.
It can be brushed on, although you’ll need a bowl or similar. It’s not the most convenient to use, and wasn’t helped by needing 10 minutes to work. This was close to the much newer WD-40 and still works well. It would be our choice for big jobs or filling a parts washer.
