How to Clean Yellowed Epoxy Grout
Epoxy grout is a durable and long-lasting material often used in kitchens, bathrooms, and other areas with high traffic and moisture. However, over time, it can become yellowed, giving your space an unappealing appearance. Luckily, there are several methods to clean yellowed epoxy grout and restore its original shine.
Why Does Epoxy Grout Turn Yellow?
Several factors contribute to the yellowing of epoxy grout, including:
- Dirt and grime build-up: Just like any other surface, epoxy grout accumulates dirt, dust, and grime over time, leading to discoloration.
- Mold and mildew growth: Moisture trapped within the grout can provide the perfect breeding ground for mold and mildew, which often appear as black or yellow stains.
- Exposure to harsh chemicals: Certain cleaning products can react with the epoxy, causing it to yellow or fade.
- UV exposure: Prolonged exposure to sunlight can cause the epoxy to degrade, resulting in yellowing.
