First, wear gloves. Because, you know, it’s still a chemical. Second, use it on hard, non-porous surfaces like doorknobs, countertops, and phones. Let it sit for 5–10 minutes—sing the “Happy Birthday” song twice, then do the Macarena.
For viruses, a 3% solution works if you’re patient. But if you’re dealing with a high-risk area (like a sick friend’s bathroom), grab a 6% or 8% solution. Just be careful—it can bleach your clothes. Oops, there goes that favorite t-shirt.
The “Tissue Test” Trick
Want to know if your peroxide is still active? Spray it on a dark cloth. If it fizzes, it’s a fighter. If it just sits there like a lazy cat, toss it. Peroxide degrades over time, especially if exposed to light. That’s why it comes in a brown bottle—it’s not shy, it’s just sensitive.
Think of it as the vampire of disinfectants: hates sunlight, fights hard, but gets a little weak after a few months.
