This is one of those ingenious tricks that makes you wonder, “Why didn’t I think of that?” Dishwasher tablets aren’t just simple bars of soap—they’re highly concentrated dirt and grease removers that are extremely powerful against stubborn baked-on grime and stains.

Your mother-in-law knows exactly how to make housework easier without buying expensive specialty cleaners. Once you understand what these little tablets can do, you’ll always keep a pack on hand—even without a dishwasher!

Here are the best household tricks your mother-in-law probably uses the tablets for:

1. Every kitchen’s nightmare: Burnt-on food in pots and casseroles
   Scrubbishing burnt-on food residue can take hours. A tablet does almost all the work.

Here’s how: Simply place the tablet in the dirty pot or casserole dish, pour boiling water over it, and let it soak for a few hours (or overnight). Afterward, the dirt can be easily wiped away without any scratching.

2. Sparkling white curtains (without a gray cast)
   Over time, curtains absorb dust, cooking fumes, or nicotine and become gray or yellowish.

Here’s how: Simply add a dishwasher tablet directly to the washing machine drum with your white curtains (select a normal wash program for curtains). The tablet acts like a gentle bleach and makes the gray cast disappear in no time. Caution: Only use on pure white laundry!

3. Cleaning the toilet (without scrubbing)
   Limescale and urinary scale deposits in the toilet bowl are often stubborn. A tablet works wonders here, especially in those hard-to-reach places with a brush.

Here’s how: Drop a tablet into the toilet bowl in the evening before going to bed. It dissolves in water and fizzes away the grime overnight. The next morning, give it a quick wipe with a brush, rinse – done.

4. How to make greasy oven doors crystal clear again
   Burnt-on grease on the oven door is extremely stubborn.

Here’s how: Put on rubber gloves, moisten the flat side of a dishwasher tablet with a little warm water, and rub it directly over the oven door glass like an eraser. The grease practically melts away. Then simply wipe it off with a damp cloth.

5. How to clean musty washing machines
   If your washing machine smells unpleasant (often due to bacteria from too many 30-degree washes), this secret weapon will help.

Here’s how: Drop two tablets directly into the empty drum and run the machine at 60 or 90 degrees (without any laundry!). This dissolves grease deposits, limescale, and soap scum in the hoses and eliminates the bad odor.

A little money-saving tip: For many of these tricks, you don’t even need to buy the expensive brand-name tablets. The cheapest tablets from the discount store serve the same purpose, as the basic chemical composition (surfactants, bleach, and enzymes) is almost identical.
