Yes, and for a number of reasons. As Best Cleaning Tools expert John Larson tells us, "When it comes to evaluating the hygienic properties of silicone toilet brushes, there are several factors to consider." He points out, first and foremost, that silicone is non-porous. "This means that it does not have tiny holes that can trap dirt, grime, and bacteria," he says. "Plastic bristles, on the other hand, are porous." He also goes on to note that silicone is also far easier to clean, more durable, and as an added benefit, more environmentally friendly — it's recyclable, after all!
