Is it real teak? If so it doesn't need any treatment and is quite ok left outside. We have a set of teak garden furniture which we bought second hand and we leave it outside 365 days of the year. It's lovely to be able to sit out on the terrace with a cup of coffee on a sunny midwinter morning.
We like the silver patina of naturally aged teak so we don't even oil it. Teak is such a hard wood that it doesn't need any preservative. We just give ours a good scrub over once or twice a year with a stiff bristle scrubbing brush to get rid of dust and grime.
If you prefer the honey-coloured look you can sand the teak to remove the patina and then oil the timber.
Don't use plastic covers on teak furniture - they trap moisture and can cause rot - it's far better to leave it in the open air to breathe.
