How to Store a Snow Blower for Summer in Missouri

In Missouri, a snow blower spends 75% of the year sitting idle in a hot, humid garage. That humidity attacks exposed steel augers and oxidizes pump fuel. Follow this 6-step checklist in late March to ensure flawless startup next November.

The 6-Step Summer Storage Checklist

1. Empty the Fuel System or Treat with Non-Ethanol Gas

Either run the fuel tank completely dry until the engine stalls, or fill the tank with 100% ethanol-free fuel mixed with double-dose Sta-Bil 360 Marine, running it for 5 minutes so treated fuel reaches the carburetor bowl.

2. Change the Engine Oil While Warm

Used oil contains acidic combustion blow-by and microscopic metal debris. Storing an engine with dirty oil causes internal pitting on crankshaft journals. Drain warm oil and refill with fresh 5W-30 synthetic.

3. Fog the Cylinder with Storage Oil

Remove the spark plug, spray a 2-second burst of engine fogging oil (or pour 1 teaspoon of clean motor oil) into the spark plug hole, and gently pull the recoil cord twice to coat cylinder walls against summer rust.

4. Wash Away Winter Salt & Touch Up Paint

Wash off caustic street salt residue. Inspect the scraper bar and housing for bare scraped metal and spray with automotive rust-inhibitor primer or fluid film.

5. Lubricate Drive Axles & Chute Gears

Apply white lithium grease or silicone spray to chute worm gears, drive cable linkages, and wheel axle bushings.

6. Elevate Tires Off Damp Concrete

If your garage floor tends to sweat during humid Missouri summer days, park the machine on a rubber mat or wooden 2x4s to prevent tire dry rot and wheel rim corrosion.

Frequently Asked Questions

Yes, but be careful. Washing road salt and winter brine off the steel auger housing and chute prevents rust. However, do NOT spray high-pressure water directly into the carburetor, electrical starter connections, or gas cap vent. After washing, run the engine for 5 minutes so exhaust heat completely dries the block.
