Caring for your sink
Clean with warm water, a mild washing-up liquid and a soft cloth, then rinse and wipe dry. Avoid abrasive pads, steel wool and harsh chemicals, and don't put very hot pans straight into the bowl. Whitebirk recommend Astonish Oven & Cookware cleaner for marks left by metal pans.

Frequently asked questions
How is the Langho fitted?
The Langho is made for inset fitting, sitting on the worktop, or undermounting beneath a solid worktop. Your fitter should cut the worktop to the actual sink, as sizes can vary by up to 2%.
How heavy is the Langho?
About 55kg. At this weight the base unit needs reinforcing, or the sink should sit on a support frame. Whitebirk recommend professional installation.
Which waste do I need?
The Langho has 2 x 3.5 inch outlets, so it takes two 3.5 inch basket strainers, standard or premium lever, or a waste disposal unit. The strainer comes with an overflow kit for the sink's overflow.
What does reversible mean on the Langho?
You can fit the sink either way round, so the smaller bowl sits on whichever side suits your tap and drainer.
