Weldtite Dirtwash citrus hand cleaner

Asked to describe Weldtite’s Dirt Wash hand cleanser in a word and I’d use two: diet Swarfega. In its defence it’s a very proficient hand cleanser for tackling most types of ground in grease and grime. However, describing it as a citrus product is a bit misleading. Sure, there’s a nice citrus orange odour but ingredients are petrochemical derived and those with sensitive skin should either rely on Latex gloves and/or minimise their exposure times to avoid discomfort.

Opening the tub and you’re greeted with a bright orange semi gel comprising of water, deodorised Kerosene with polymer grains and parabens commonly used in cosmetics and deodorants as a preserve/stabilizer to prevent solutions separating. Some studies show a link with cancers and reproductive health problems, so on this basis I’d avoid regular or prolonged exposure.

Application is pretty much identical to other industrial cleaners. Scoop a liberal helping into your hands using your fingers and massage enthusiastically into the affected areas for a couple of minutes, or until the grime begins to lift before rinsing clean using warm tap water. Our test sample worked wonders on less sophisticated oils, greases, ground in road grime and preserves such as Waxoyl but wasn’t nearly so effective on more chemically complex Teflon/marine based pastes commonly applied to bottom brackets, headsets and other higher stressed component areas.

The 500ml tub represents good value for money, ample for the needs of most home mechanics. However, there are concerns over some of the chemical groups employed in this and many similar products. Used daily for a week, my hands felt noticeably drier, especially tackling particularly stubborn grime. While I'd be happy enough to use it infrequently, I would avoid prolonged exposure. Frequently fettlers should stick to the humble Latex examination gloves and a good moisturiser.

Verdict

Cheap and relatively effective hand cleanser.
