Why didn't I think of asking them? Doh.
Oh well, prompted by your post, I checked the manufactuirers website, and
found this in the FAQ:
"
How do you clean teak?
Once teakwood has weathered the colour will be enhanced by an annual scrub,
in the Spring, with soapy water to remove accumulated dirt. Alternatively
you may use a pressure hose with a fan or multi-nozzle jet. However, great
care should be used since failure to abide by recommended procedures may
result in permanent damage to the furniture. Where a gauge is fitted it
should be set to a pressure of 60-80 bar (900-1200 psi). A distance of
15-20cm (6-8") should be maintained between the nozzle and the surface to be
cleaned. Care should be taken not to direct the water jet directly into
joints.

Thanks all.
