how do i get the smell out of the plastic jar lid? it smells like old garlic no matter how i wash it.

Diagnosis

The Hamilton Beach Wave Crusher 54221 utilizes a plastic lid assembly equipped with a flexible silicone sealing gasket. Plastic and silicone are porous materials, meaning they contain microscopic voids that act like a sponge. When you blend pungent ingredients—specifically garlic, onions, or curry—the volatile organic compounds (sulfur compounds) penetrate these pores and bond to the material. Because these oils are hydrophobic, standard dish soap simply slides over the surface without penetrating the pores to lift the trapped odors. Over time, these odors oxidize, creating a "stale" or "old garlic" scent that persists even after the lid looks visually clean. If you smell the scent most strongly around the rim where the lid meets the jar, the silicone gasket is the primary culprit, as it is more permeable than the hard plastic shell.

How to Fix It

To fully neutralize the odors, you must break the chemical bond between the sulfur compounds and the porous material. Follow these exact steps:

1. Complete Disassembly: Do not just wash the lid. Use a blunt butter knife or a plastic pick to gently pry the silicone sealing ring out of the lid groove. If the ring remains in place, the cleaning solution cannot reach the underside of the seal where the most odor accumulates.
2. The Acidic Soak: Create a solution of 1 part distilled white vinegar to 2 parts hot (not boiling) water in a shallow basin. Submerge the plastic lid and the silicone ring separately. Let them soak for a minimum of 4 hours, or ideally overnight. The acetic acid in the vinegar breaks down the alkaline odor molecules.
3. Abrasive Neutralization: Create a thick paste using 3 parts baking soda and 1 part water. Apply this paste liberally to the silicone ring and the interior grooves of the lid. Use a soft-bristled toothbrush to scrub the paste into the pores of the silicone. Let the paste sit for 30 minutes.
4. Final Purge: Rinse both components under high-pressure warm water. Use a fragrance-free dish soap for a final light wash to remove any remaining baking soda residue.
5. Air Cure: Do not towel-dry. Place the components on a drying rack in a well-ventilated area or under direct sunlight for 2 hours. UV rays help break down remaining organic compounds.

If That Didn't Work

• Denture Tablet Deep Clean: Fill a bowl with warm water and drop in two denture cleaning tablets (like Polident). These contain effervescent agents and potassium peroxymonophosphate, which are specifically designed to lift organic stains and odors from porous acrylics. Submerge the lid and gasket for 60 minutes.
• Hydrogen Peroxide Bath: For extreme cases, soak the silicone ring in a 3% hydrogen peroxide solution for 30 minutes. This oxidizes the trapped organic matter. Rinse thoroughly with water afterward to ensure no peroxide remains before reassembling.
• Activated Charcoal Absorption: Place the dry lid and gasket in a sealed Tupperware container with a fresh activated charcoal sachet or a bowl of dry coffee grounds for 48 hours. The charcoal/coffee will act as a desiccant and pull the remaining scent molecules out of the plastic.
• Component Replacement: If the plastic has become "pitted" or scratched, the odors are trapped in physical gouges. In this case, the only solution is to replace the lid assembly. Search for the Wave Crusher 54221 replacement lid to ensure the seal remains airtight.

Heads Up

• Avoid Boiling Water: Never boil the plastic lid or silicone ring. Excessive heat can warp the plastic, causing the lid to fit loosely and lead to leaks during high-speed blending.
• Avoid Bleach: Do not use concentrated bleach on the silicone seal. Bleach can degrade the elasticity of the rubber, leading to permanent cracks and a loss of suction.
• Pre-Treatment Tip: When blending garlic or onions in the future, rinse the lid immediately with cold water. Hot water can "set" the odors into the plastic if they aren't rinsed off quickly.
• Seal Check: Always ensure the silicone ring is seated perfectly flat in its groove after cleaning. A pinched ring will cause the blender to leak from the top during a "Crush" cycle.
