What humidity should I set my dehumidifier to?

[The Cyclist]

Dear Lotus Enthusiasts,

I treated myself to a dehumidifier this winter - an absorbent rather than a refrigeration type. But, of course, how often it is running depends on the target humidity I set. Currently 60%. Is that low enough?

The previous refrigerant one was clearly ineffective in the cold and ran a lot to little purpose, so I would like to use this one efficiently to try & recoup the expense.

Some tips for winter storage in this article from Hagerty ......

Including this paragraph on humidity....

The article is misleading in that by "setting it high" they meant a lower relative humidity. 40% will kill dust mites so I'd put it there. 40% is also about as high as it gets in Death Valley which goes below 20% in summer just for perspective.

Suppose it depends on what part of the world you are in and how well your garage is sealed in UK I would stick with 55-60% RH if you try to go too low it will be running all the while and may not get to target if sealing is poor. Clean a bit of sheet steel with wire wool leave it in there see if rust forms on it

Thank you everyone for your comments, I think the view settles to being a smidge less than I have now - 55%.
