Will dehumidifier help with rust?

Using a dehumidifier to introduce dehumidified air into your sandblasting booth will significantly reduce RH, which will, in turn, decrease the risk of ‘flash rusting’. Reducing humidity to below 50% RH will also allow you to ‘hold the blast’ on uncoated steel for days.
