Your tools will last longer if you keep them clean. Scrape off the dirt before you put them away, using sandpaper to remove heavy mud or rust. To protect metal tools from rust, pour motor oil into a bucket of sand. Dip the clean tool blade into the bucket, and work it up and down a few times to clean any stubborn soil and lubricate the blade. If you like, you can store your tools in the bucket of sand and oil.
Hoses take more abuse than most garden tools.
To prolong their life, store them off the ground in large pottery or plastic pots or on a hose reel. If you see a kink in the hose, straighten it out before walking away. Instead, use a flat stick, such as a paint stirrer, to scrape off caked on mud. If you can't get all the mud off with a scraper, use sand paper. Store hoses up off the ground to minimize damage, either hanging them coiled on the wall or coiled inside an oversize clay pot.
