If you're wondering how to maintain a sprayer, start by checking your equipment before every use. Properly taking care of your sprayer can extend the life of the machine. It's important to empty your sprayer and clean the inside of the tank after each use. Evaluate your sprayer's parts to ensure they are clean and in good condition. Inspect the plumbing for sagging or kinked hoses that can block solution and cause chemicals or solution build up which could have a negative effect on the sprayer's performance.
