Liquid resin should never be rinsed away with water, whether from your tools, work surface, or skin. Doing so can lead to environmental harm and damage in your workspace. Here’s how to safely manage and dispose of liquid resin, and why responsible handling matters.
Why Avoid Rinsing Liquid Resin?
Liquid resin contains components that do not break down in water and can be hazardous to plumbing, local waterways, and ecosystems. When rinsed down the drain, uncured resin can cause blockages in pipes and release pollutants into the environment. For these reasons, always avoid washing uncured resin off tools, containers, or your skin directly into sinks or drains.
Safe Ways to Clean Up Resin
For cleaning tools and surfaces, scrape off as much resin as possible with disposable paper or plastic, and allow the residue to cure; once fully hardened, it can be disposed of as household waste in most areas. For remaining sticky residue, use a gentle, natural cleaning product such as Strong Technical Degreaser for Resin Projects – 100% Natural Formula. This plant-based cleaner effectively removes resin without resorting to harsh solvents and is kind to skin and a range of surfaces.
- Wipe with absorbent paper before cleaning further.
- Always wear gloves when handling uncured resin.
- Avoid contact with drains at every stage.
When This Matters Most
Spills and accidental splashes are more likely when working on larger projects or using intricate moulds. In these situations, cover your surfaces in advance with a Protective Sheet Film for Resin Projects, 4x4m Surface Cover so that any drips can be contained and disposed of correctly without contaminating washwater or surfaces.
