That’s actually a common “smart hack” — many people buy dishwasher tablets even without owning a dishwasher because they’re powerful multi-purpose cleaners.
Here’s likely the trick your mother-in-law is using 👇
🧼 Why dishwasher tablets are useful
They’re designed to:
- Cut grease
- Remove stains
- Kill bacteria
- Work in hot water
So they can be used for deep cleaning around the house.
🏠 Popular uses (no dishwasher needed)
1. 🍳 Cleaning burnt pots & pans
- Put 1 tablet in the pot
- Add hot water
- Let it sit 30–60 minutes
- Scrub lightly → stains come off easily
2. 🚽 Toilet deep cleaning
- Drop 1 tablet into the toilet bowl
- Let it dissolve for 20–30 minutes
- Brush and flush
3. 🧴 Removing tough stains
- Dissolve a tablet in warm water
- Use it to clean:
- Greasy kitchen surfaces
- Tiles
- Oven trays
4. 🗑️ Cleaning trash bins
- Fill with hot water + 1 tablet
- Let sit, then rinse → removes smell and grime
5. 🪟 Glass & plastic items
- Helps remove stubborn residue from bottles or containers
⚠️ Important cautions
- Don’t use on delicate surfaces (wood, aluminum, non-stick pans repeatedly)
- Wear gloves if you have sensitive skin
- Keep away from children (they’re strong chemicals)
💡 Why “one pack lasts a year”
Because:
- You only use 1 tablet at a time
- Cleaning isn’t daily like dishwashing
So yes—your mother-in-law is being pretty clever 😄
If you want, I can share a few less-known but very effective uses that most people don’t know about.
