Materials
Non-porous materials are the only ones worth buying. Here's how to tell them apart.
Body-safe silicone is the standard for most quality products — non-porous, flexible, and easy to clean. It has a slightly matte, velvety texture. ABS plastic (hard, smooth, usually in handles or buttons) is also non-porous. Glass and stainless steel are non-porous and can be fully sterilized. TPR and TPE are softer and often cheaper, but porous — they absorb bacteria and oils that can't be fully removed by cleaning, and they degrade faster. Jelly materials are the worst offenders: porous, often made with plasticisers that can cause irritation, and not worth using. If a product listing doesn't specify silicone, ABS, glass, or stainless, assume porous until confirmed.
- Silicone: slightly matte, velvety — the right texture for a body-safe product; shiny or rubbery feel usually means TPR
- ABS plastic: hard, smooth, non-porous — common in handles and controls, safe on contact
- Glass and stainless steel: non-porous, can be boiled or run through a dishwasher for full sterilization
- TPR / TPE / jelly / rubber: porous — bacteria survive cleaning, material degrades over time; not recommended
