How to Clean Silicone Bongs and Pipes: Safe Methods

Silicone smoking accessories are durable and shatterproof, but they require different cleaning methods than glass. Using the wrong cleaner (like isopropyl alcohol) can permanently damage silicone. Whether you're cleaning silicone containers from MunchMakers' smell-proof storage collection or silicone pipes, this guide covers safe, effective cleaning techniques.

Quick Answer

To clean silicone: Use warm water and dish soap only—never isopropyl alcohol. Scrub with soft brush, rinse thoroughly, air dry completely. Most silicone pieces are dishwasher safe (top rack, no heat dry). For odors, use baking soda paste overnight.

Why Silicone Requires Different Cleaning

The problem with alcohol:

• Isopropyl alcohol degrades silicone over time
• Causes brittleness and cracking
• Can lead to discoloration
• May affect food-grade safety

What works for silicone:

• Dish soap and water
• Baking soda (for odors)
• Dishwasher (top rack)
• Freezing method (for stubborn resin)

The Wikipedia article on silicone explains how this material's unique properties make it resistant to extreme temperatures while being susceptible to certain solvents.

The Soap and Water Method

This is your primary cleaning technique for silicone.

Step 1: Disassemble

Remove all non-silicone parts:

• Glass bowls and downstems
• Metal screens
• Any removable pieces
• Clean these separately with appropriate methods

Step 2: Rinse with Warm Water

Initial rinse removes loose debris:

• Use warm (not hot) water
• Shake to dislodge loose particles
• Let water flow through all openings

Step 3: Add Dish Soap

Apply dish soap inside:

• Few drops of standard dish soap
• Dawn, Palmolive, or similar work well
• Fill partially with warm water
• Shake to create suds

Step 4: Scrub

Use soft-bristled brush:

• Bottle brushes work well
• Pipe cleaners for narrow areas
• Don't use abrasive scrubbers (can scratch)
• Focus on areas with visible buildup

For stubborn spots: Let soapy water sit for 30-60 minutes before scrubbing.

Step 5: Rinse Thoroughly

Remove all soap:

• Multiple rinses with clean water
• Shake to clear all passages
• Continue until water runs clear
• No soapy residue should remain

Step 6: Dry Completely

Air dry before use or storage:

• Set upside down to drain
• Ensure all water exits
• Let air dry completely
• Don't store while damp (prevents mold)

The Dishwasher Method

Most food-grade silicone is dishwasher safe.

Before Dishwashing

Check:

• Manufacturer says dishwasher safe
• Remove all glass and metal parts
• Ensure it's food-grade silicone

Dishwasher Settings

Do:

• Use top rack only
• Normal cycle
• Standard dish detergent

Don't:

• Use heated dry cycle (can warp)
• Place near heating element
• Use with sharp utensils that could puncture

After Dishwashing

• Inspect for remaining residue
• Air dry completely before reassembling
• Check for any damage or warping

The Freezing Method

For resin that won't budge with soap and water.

How It Works

Silicone is flexible, resin is not. Freezing makes resin brittle while silicone remains pliable—allowing you to flex the piece and break off frozen resin.

Steps

1. Rinse to remove loose debris

2. Freeze for 2-4 hours (or overnight)

3. Remove from freezer

4. Immediately flex the silicone—bend, twist gently

5. Frozen resin will crack and fall off

6. Rinse with warm water

7. Repeat if needed

Tips

• Work quickly before silicone warms up
• Don't force if something won't release
• Can combine with soap cleaning after

Removing Odors from Silicone

Silicone can absorb odors over time. Here's how to deodorize:

Baking Soda Paste Method

Most effective for stubborn odors:

1. Make thick paste (3:1 baking soda to water)

2. Apply inside piece, coating all surfaces

3. Let sit overnight (8+ hours)

4. Rinse thoroughly

5. Repeat if smell persists

Baking Soda Soak

For lighter odors:

1. Dissolve 2 tablespoons baking soda in warm water

2. Soak silicone piece overnight

3. Rinse and dry

Sunlight Method

Natural deodorizing:

1. Clean piece with soap and water first

2. Place in direct sunlight for 4-6 hours

3. UV rays help break down odor-causing compounds

4. Don't leave for extended periods (can fade colors)

Vinegar Rinse

Mild deodorizing:

1. Rinse with diluted white vinegar (1:1 with water)

2. Follow with thorough water rinse

3. Works for light odors

What NOT to Do

Never Use Isopropyl Alcohol

• Degrades silicone structure
• Causes brittleness over time
• Can create cracks and tears
• Shortens lifespan significantly

Avoid Harsh Chemicals

Don't use:

• Bleach
• Acetone
• Hydrogen peroxide (high concentrations)
• Commercial glass cleaners
• Abrasive cleaners

Don't Use Extreme Heat

• No boiling water (can warp)
• No microwave
• Keep away from open flames
• Skip heated dry in dishwasher

Avoid Abrasive Tools

• No steel wool
• No hard-bristled brushes
• No abrasive sponges
• Can scratch and harbor bacteria

---

Cleaning Frequency

Daily/After Each Use

• Empty water
• Quick rinse with clean water
• Let air out before storage

Weekly (Regular Users)

• Full soap and water clean
• Brush scrub all surfaces
• Check for odor buildup

Monthly (Or As Needed)

• Deep clean with freezing method if needed
• Baking soda treatment for odors
• Inspect for damage or wear

Cleaning Different Silicone Pieces

Silicone Bongs

• Remove glass bowl and downstem first
• Clean base and neck separately
• Ensure ice catchers are cleared
• Flexible design makes interior access easier

Silicone Pipes

• Usually simpler to clean
• Pipe cleaners for the bowl and chamber
• Soap and water works well
• May need more frequent odor treatment (smaller pieces trap smell)

Silicone Containers

• Same soap and water method
• Pay attention to lid seals
• Replace if seal becomes compromised
• Don't store wet (can grow mold)

Silicone Mats/Pads

• Usually just wipe with damp cloth
• Soap and water for deeper clean
• Lay flat to dry
• Can often go in dishwasher

---

Preventing Buildup

Tips for easier cleaning:

• Change water frequently (if applicable)
• Don't let resin dry on surfaces
• Quick rinse after each session
• Store in clean, dry location
• Use screens to reduce direct contact

---

When to Replace

Silicone is durable but not permanent. Replace if you notice:

• Cracks or tears
• Persistent odor after deep cleaning
• Discoloration that affects function
• Loss of flexibility
• Damaged seals or connections

Average lifespan: 2-5 years with proper care, depending on use frequency.
