Which chemicals or solvents are safe to use with ECHO® sprayers?

Proper cleaning of the sprayer should be performed after every use. Always check the chemical manufacturer’s label for specific cleaning instructions. Do not leave any chemicals in the tank when the sprayer is not in use. Different chemicals may require specific neutralizing or removal methods to eliminate harmful residues. Use the cleaning steps listed below only if no chemical manufacturer instructions are provided. Never use hot or warm water to clean a sprayer. Only cold water should be used. Hot/warm water will soften the pressure chamber causing premature wear.

•  Cleaning After Using Fertilizers, Pesticides, Fungicides, and Similar Chemicals: 
  • Mix 1 gallon of cold water with 6–8 tablespoons of white vinegar.
  • Pour the mixture into the sprayer tank and gently shake or swirl it to make sure the solution reaches all areas inside.
  • Pressurize the sprayer and spray the vinegar solution through the nozzle.
  • Repeat this process at least twice to ensure all chemical residue is removed.
  • After rinsing with the vinegar solution, mix a small amount of cold water and dishwashing detergent in the tank and repeat the cleaning process.
  • Finish by flushing the sprayer with clean, cold water through both the tank and spray wand.
• Cleaning After Using Oil-Based Deck Stains and Sealers: It’s important to clean your sprayer within one hour after using any oil-based deck stain or sealer. If the material is allowed to dry inside the sprayer, it can damage seals and O-rings, requiring replacement. 
  • Pour 1 quart of denatured alcohol (available at most hardware stores) into the tank.
  • Gently shake or swirl the alcohol to make sure it reaches all areas inside the tank.

  • Pressurize the sprayer and spray the alcohol through the nozzle.

  • Repeat this process at least twice to ensure all stain or sealer residue is removed.

  • After cleaning with alcohol, mix cold water and a small amount of dishwashing detergent in the tank and repeat the rinsing process.

  • Finish by flushing the sprayer with clean, cold water through both the tank and spray wand.

  • Notes: Sprayers used for deck stains or sealers should not be used for fertilizer or pesticide applications, as residue may cause damage or contamination.
