Borosilicate glass dildos are among the easiest sex toys to keep, they're non-porous, chemically inert, and sterilisable to surgical standard.
Everyday cleaning
After every use:
- Warm water, not hot enough to thermal-shock the glass. Lukewarm is correct.
- Fragrance-free antibacterial soap, Carex Original, Cussons Soft & Gentle, or any unscented liquid soap. Avoid scented soaps (residue lingers).
- Thirty seconds of attention, front, back, base, any textured surfaces.
- Rinse thoroughly.
- Pat dry on a clean cloth or paper towel.
- Air-dry for a few minutes before storing.
Deeper sterilisation
For thorough sterilisation between partners, between body parts, or after long-term storage:
Boiling
Submerge in boiling water for 3 minutes. Use a saucepan reserved for the purpose. Lift out with tongs; allow to air-cool on a clean surface.
Important: add the glass to room-temperature water and bring to a boil together, rather than placing cold glass into already-boiling water. Sudden temperature change can shock-fracture borosilicate glass, even though it's designed for thermal resistance.
Dishwasher
Top-rack dishwasher, normal cycle, no detergent (residue is hard to remove from textured surfaces), no heated drying. Effective for batch-cleaning multiple glass pieces; mind the rack position so the glass doesn't touch the heating element directly.
70% isopropyl alcohol
Wipe with 70% IPA on a microfibre cloth, then rinse with water afterwards. Useful when boiling or dishwashing isn't practical.
The inspection check
Before every use, inspect the glass:
- Look for visible chips or cracks, particularly at the base, the head, and any textured areas. A chip is the most-common point of failure under load.
- Feel along the surface with a fingertip, any rough spots, cracks, or surface damage means the piece should be retired.
- Hold up to light, internal fractures are sometimes visible as cloudy lines inside the glass.
Cracked or chipped glass can fracture under use. The body of a quality borosilicate dildo can withstand significant force, but any pre-existing damage compromises that strength.
Storage
- Original padded pouch or a foam-lined drawer space, protect from impacts during storage.
- Don't store in direct contact with other hard objects, glass-against-metal contact in storage can chip the surface.
- Room temperature, glass tolerates temperature extremes but rapid changes can shock-fracture. Don't store next to a radiator and use immediately afterward; let it equilibrate.
What destroys glass dildos
- Impact, dropping on tile or hard floors. The single most-common cause of failure.
- Rapid temperature change, cold-to-boiling or hot-to-cold without gradual transition.
- Surface scratches from abrasive cleaners, never use scouring pads, bleach, or harsh chemicals.
Lifespan
A quality borosilicate glass dildo, properly stored and inspected, lasts indefinitely. There's no material degradation; only structural damage. Many users own glass pieces for 10+ years without any decline in performance.
Lubricant compatibility
Glass works with every lubricant type, water-based, silicone-based, and oil-based all leave no residue and don't react with the glass surface. This makes glass the most-flexible material for lubricant choice.
