We did a bang up job using a cleaner on a 2 year old deck in NH. However the weather is not cooperating and I don't want to stain it too close to rain. We will be gone for work for almost 3 weeks. Do I have to use the cleaner again before staining or will it retain it's look and prep for the 21 days we are gone?
Most likely after that long you will need to redo do but very lightly.
