PBW is alkaline, StarSan is acidic. I don't think you want to soak hoses long term in either one. Rinse with clear water right away. Use a line cleaning brush (e.g. https://www.morebeer.com/products/line-brush-12-48.html?site_id=7) appropriately sized for your tubing, with PBW to scrub the inside. Rinse with StarSan if you have some available and feel like using it, but there is absolutely no reason to soak anything in StarSan for more than a few minutes. Then hang vertically to drip and dry, preferably in full sun, but anywhere warm enough to dry out reasonably fast. Full sun can eventually cause your tubing to dry out and crack, but all that UV is great for killing bacteria.
