How to Clean A Microwavable Heating Pad
Microwavable heating pads are a favorite muscle pain relief tool for those who suffer from menstrual cramps, arthritis pain, stiffness and more.
However, the more people love using their microwavable heating pad, the more likely they will eventually get dirty.
So how do you clean a microwavable heating pad?
Like all fabric-based products, paying close attention to the materials that make up your microwavable heating pad is key to keeping it clean.
By following manufacturers’ instructions and investing in covers, it is easy to keep a microwavable heating pad clean and usable for many years to come.
But what if you have a homemade microwavable heating pad that didn’t come with instructions?
Is It Hard to Clean a Microwavable Heating Pad?
Most microwavable heating pads are easy to take care of, if you know how.
Heating pads are simple, yet very effective tools to manage muscle pain.
Made from a simple cloth bag and filled with a reheatable filling material, constructing one isn’t very hard.
However, figuring out how to wash and clean something filled with rice, flax, or beans can be slightly daunting.
If you buy a microwavable heating pad from a trusted online retailer, such as LavaHQ, chances are that they included information on how to clean the product.
However, if your microwavable heating pad did not come with instructions, here are some helpful tips on how to best clean your heating pad.
How Do You Clean a Microwavable Heating Pad
How you clean a microwavable heating pad depends on two factors:
- The material used to make the bag
- The filling of the bag
Material and Fabric Used to Make Microwavable Heating Pads
It is very important to be aware of what fabrics are used in making your microwavable heating pad.
Various online sellers and retailers, especially in the hand crafted sector, use a variety of materials to construct the bag of the microwavable heating pad.
Generally, this material is a natural fiber fabric, such as linen (made from flax), cotton, and hemp materials.
However, some may unwittingly use synthetic or polyester material (which is not recommended for construction of microwavable heating pad due to the flammability risk and the heating of chemicals in the material).
Reheatable Fillings Used in Microwavable Heating Bags
The materials used to fill a microwavable heating pad usually include pantry items such as rice, beans, flax, wheat, etc.
Due to the perishable nature of these items, the filling of a microwavable heating pad should NEVER get wet.
If the foodstuffs inside of a microwavable heating pad get wet, then there is an increased risk of rot and mold developing inside of the bag.
Not only is it unhealthy to be reheating rotting foodstuff inside a microwave, but the heating of spoiled food can smell up a house and ruin a microwavable heating pad.
If using nonperishable microwavable heating bag fillers such as lava sand, clay beads, sand, and other mineral based substances, the risk of rot is non-existent.
That means that if a heating pad filled with such items gets wet, there is no chance that anything will spoil inside.
Unfortunately, the fabric case itself is still prone to mildew, so if moisture is trapped inside the filling it can cause the covering to smell.
Despite nonperishable materials not rotting, it is not recommended to wash a microwavable heating pad in a washing machine.
Small particles of sand or pebbles may leak out of the bag and ruin the load of laundry.
Also, it is not recommended to saturate a microwavable heating pad with soapy water since the soap and detergent might become trapped inside the filling material.
Instructions on How to Wash a Microwavable Heating Pad
Most microwavable heating pads can be spot cleaned.
However, if there is a major stain or spill on one it might need a thorough cleaning.

- Examine filling for any signs of rot or burning and replace spoiled material.

Microwavable Heating Pad Care Frequently Asked Questions (FAQ)
Can You Throw A Microwavable Heating Pad Into a Washing Machine?
It is ill advised to throw a microwavable heating pad into a washing machine without emptying the filling contents first.
If a microwavable heating pad is filled with food items such as rice, wheat, flax, etc., the foodstuffs will absorb the water in the wash along with some of the laundry detergent.
If placed in a dryer, such foodstuffs have the potential to catch on fire if subjected to intense heat.
If a microwavable heating pad is washed in a washing machine and then left to air dry, rot and spoilage can set in to the filling, causing a strong and unpleasant odor to arise when it is heated in the microwave.
Microwavable heating pads with nonperishable fillers should also not be placed into a washing machine without the contents emptied.
Although there is no risk of rot, the granular nature of the filler may leak out of the fabric and could destroy the washing machine.
Can You Use Bleach to Clean the Fabric of a Microwavable Heating Pad?
It is always advised to follow the care instructions of the fabric or microwavable heating pad for instructions on how to best clean it.
However, because of the natural characteristics of the fabric generally used to make a microwavable heating pad, it is strongly recommended NOT to use bleach.
Bleach not only can alter the coloring of the fabric if applied, but can weaken and even break the fibers which make up the material.
Instead, gentle detergents or a paste made from half baking soda and half vinegar is recommended to help get rid of stains.
How to Clean My Rice Sock
If your microwavable heating pad happens to be a sock filled with rice knotted at the end, then washing it is very simple.
Unknot the sock and pour out the rice.
Inspect the rice to find any signs of burning, rot, or bugs.
If the rice shows signs of any of the above, dispose of rice.
Once the sock is empty, launder it according to the manufacturer's instructions.
Once the sock has been cleaned, replace the rice or add new rice and knot up the end of the sock again.
Should I Toss Out My Dirty Microwavable Heating Pad?
Depending on the amount of effort it takes to clean a microwavable heating pad, it may be easier to throw it out and invest in a new one, especially if its contents have been saturated with liquid.
If your microwavable heating pad is a cheap piece of fabric that is sewn all about and contains food such as rice, wheat berries, corn, flax, etc, it may be in your best interest to dispose of it and make a new one.
Another sign that a microwavable heating pad should be discarded is if a strange odor is emitted while being heated in a microwave.
This odor can be a sign of burning or rot that is occurring inside the heating pad.
For heating pads with nonperishable fillers, such as lava sand and clay beads, the fabric casing can be discarded and the filler reused in a new microwavable heating pad.

Invest in a few cute covers for your heating pad to make cleaning it a breeze, and if the time comes that you need to wash it, make sure to follow the steps mentioned above.
