- Invest in quality. A $9 bottle that lasts the whole season is less expensive then cheaper bottles that need to be repeatedly replaced. Look for commercial-grade sprayers used by cleaning services or greenhouses. You may also want to consider a pressurized sprayer.
- Clear the uptake tube and nozzle regularly. Spraying hot water through the equipment will clear out any clogs.
- Do not set spray bottles on the ground. To avoid nozzle-clogging dirt as well as the risk of being stomped by human and equine feet, place bottles on a tack trunk or chair as you work.
- Go natural. Sea sponges tend to be more durable than man-made varieties.
- Rinse well. Soap or liniment residue can break down a sponge over time.
- Dry thoroughly. Mildew can grow in a perpetually wet sponge. Store sponges in mesh bags or a hanging produce basket to allow air to circulate and facilitate drying.
