Tips and Hints For Proper Use of Harvest Guard Reusable Canning Lids
- Always wash and thoroughly clean lids and rings prior to use. Harvest Guard Reusable Canning Lids and Rings are dishwasher safe. Never clean lids with bleach of other oxidizing agents or strong acids.
- Read instructions before use and always follow proper USDA recommended canning practices. Improper use can cause seal failure and possible injury due to hot temperatures of canned food products.
- Use standard mason jar metal band when processing. Overtightening of metal bands can cause seal failures due to trapped pressure in the jar.
- Never tighten metal bands on jars with lids that appear convex or “domed”. This is indicative of trapped pressure in the jar which can release and cause severe burns or injury.
- Always exercise extreme caution when removing hot jars from pressure canner or water bath as injury can result. When tightening metal bands after processing, cover jars with a kitchen towel to prevent accidental contact with hot jars or contents.
- Allow canned products to cool for 12-24 hours at room temperature before removing metal bands. During cooling period, ensure jars are not directly under air conditioning vents as this may affect proper cooling and sealing of lids.
- After jars are cool to the touch, remove metal band and gently lift upward on plastic lid to ensure proper seal. Failed seals will lift without any resistance. If a failure occurs, re-process according to USDA approved methods, or consume un-sealed products immediately.
