🦷 This $300 Machine Makes Her $500/Day

Back in high school, I had this idea to buy a mobile carpet cleaning machine and offer carpet, rug, and mattress cleaning to friends and neighbors. It just made sense to me… buy a machine nobody wants to own, and instantly you’ve got a valuable service people will pay for.

Today’s side hustle is built on that exact same idea.

I came across a woman on Reddit making $500 a day running a mobile teeth whitening business. Instead of working out of a salon, she bought a professional teeth whitening machine off Amazon and now she drives to customers' homes and whitens their teeth right from their couch.

She’s now pulling in $5,000 a month working just a few days a week.

Here’s exactly how she did it 👇

🚗 How This Business Works

💰 Charge per session: $100–$150 ⏳ Time per session: 45 minutes to 1 hour 📅 Clients per day: 3–5 (or more, if you scale up) 📈 Potential earnings: $500+/day, $10K+/month if consistent 🔁 Recurring Customers: Most clients book every 3–6 months for touch-ups

The best part? There’s little competition. Most teeth whitening services are overpriced at high-end salons or dental offices, leaving a huge gap in the market for an affordable, at-home alternative.

🚀 How to Get Started

1️⃣ Buy a Teeth Whitening Machine 🛍️

• Professional LED whitening machines cost $300–$600+.

• Whitening gel kits & supplies cost around $100 to get started.

2️⃣ Practice First 🏡

• Try it on yourself, friends, or family to build confidence.

• Offer discounted “first-time” treatments to early customers for social proof.

3️⃣ Set Up a Booking System 📅

• Use a free scheduling tool like Calendly or Square Appointments to manage bookings.

• Accept payments via Venmo, CashApp, or Stripe.

📢 How to Get Customers

📍 Local Facebook Groups: Post about your service in your local community Facebook page sharing a picture of yourself cleaning teeth and a before/after photo.

🗣️ Word-of-Mouth: Tell friends, family, coworkers about your new business.

📸 Personal Social Media: Regular before/after photos keep engagement high and drive bookings.

📬 Flyers & Business Cards: Drop them at coffee shops, gyms, salons, and high-end apartment complexes.

🛠️ What It Costs to Start

🔹 Machine & Supplies: $400–$700

🔹 Marketing Budget: $0 (social media & referrals)

🔹 Ongoing Costs: Low—mostly just restocking whitening gel

🤑 Profit Margins: 80%+ (since each session only costs a few bucks in materials)

🚧 Challenges & What to Know

📝 Legal Stuff: Some states have restrictions on non-dentists offering whitening services. Check local regulations

🦷 Customer Expectations: Be clear that results vary. Some need multiple sessions.

❄️ Seasonality: Demand is high year-round, but especially before weddings & holidays

🎯 Why This Works

✅ High Demand + Convenience: People love the idea of getting their teeth whitened at home.

✅ Low Cost, High Profit: Minimal startup costs with insane profit margins.

✅ Recurring Revenue: Clients return every 3–6 months for touch-ups!

✅ Scalable: Once booked up, you can train someone to take appointments for you.

This is one of those side hustles that’s simple and fun for the right person. If you’re looking for a unique business you can start with just a Facebook post and a few flyers around town, this could be perfect for you.

Enjoy the day!
