Storing a Sprayer Between Uses

How a bottle is stored decides whether it works next time, and the rules differ by liquid.

The General Principles

Cool, out of direct sunlight, upright, and not full of something that will degrade.

Sunlight breaks down plastics and accelerates rancidity in oil. Heat does both faster.

A bottle stored beside a hob or on a sunny windowsill is being aged deliberately.

By Liquid

• Oil: store cool and dark, and flush the mechanism before long storage
• Water: empty rather than leaving it standing
• Plant feeds and treatments: empty, flush and label
• Cleaning products: labelled, upright, out of reach of children
• Anything sugary or salty: flush after every use

Where a manufacturer specifies hand washing and warns against dishwashers, of the kind noted at https://flairosol.us.com/, that applies to storage preparation as much as to routine cleaning.

Never Store an Oil Sprayer Full and Idle

Oil left in a nozzle for months polymerises into a hard varnish that warm water may not shift.

A sprayer put away with oil in it is frequently a sprayer that never works again.

Empty, flush with warm soapy water, rinse, dry with the head off.

Dry With the Head Off

So the inside of the mechanism can air rather than staying damp in a closed bottle.

A sealed damp mechanism is where biofilm forms.

Freezing

Water expands when it freezes and can crack a bottle or split a mechanism.

Anything stored in a garage or a shed over winter should be emptied first.

Keep Them Separated

Cleaning products nowhere near food or cosmetic bottles.

Label Before Storing

Contents and date.

Check Before Refilling

Smell and look inside.

Flush Before Long Storage

Especially anything that held oil.

Empty Before Frost

Water expands and splits mechanisms.

Store Away From Heat and Light

Which ages both bottle and contents.

Keep Cleaning Bottles Separate

Nowhere near food or cosmetic ones.

Upright, Always

Which keeps the dip tube where it should be.

Check Before Refilling

Look and smell inside first.

Label Before Storing

Contents and date, in permanent marker.

Dry With the Head Off

So the mechanism airs rather than sitting damp in a closed bottle.
