1. How to clean with abrasives - try to remove water stains from a ceramic washbasin!
【degree of difficulty★★☆☆☆】

Washstands used daily are prone to stains caused by moisture and soap.
Many people may be able to prevent mold with routine cleaning, but they may not be able to remove water stains.
Water stains can be difficult to remove as they accumulate, so it is important to clean them before they become noticeably dirty.

Stubborn water stains on ceramics; water-resistant abrasive paper is recommended for this area among abrasive materials.

It is durable and tear-resistant, so one piece can be used for a long time.

Since it is sandpaper, it can of course be used for DIY, etc. (paint coating, woodworking).

2. How to clean with abrasive materials - remove burnt on induction stove by polishing!
【degree of difficulty★★☆☆☆】

Induction stoves have been touted as being flatter and easier to clean than gas stoves, but after years of use, they can become greasy and burnt. ...... It is true that the flat surface is easy to wipe clean, but it is impossible to take care of burnt-on stains during daily cleaning.

In fact, these stains can be easily removed with cleanser and aluminum foil.

～What to prepare～
・Cleanser
・Aluminum foil
・Wet rags
・Dry rag

Turn off the induction stove and begin working when it reaches room temperature.
Dab a small amount of cleanser and polish with rolled aluminum foil (about 15 cm).
In fact, the cleanser contains microscopic abrasives, and these particles remove dirt.
When the stain is removed, wipe with a clean cloth to remove the cleanser.
Finally, wipe up any remaining water with a dry cloth to complete the process.

In fact, along with cleansers, toothpaste also contains fine abrasive particles.
Abrasives are much more familiar to us than we imagine.

3. How to clean with abrasive materials - Try to revive diatomaceous earth mats that have lost their water absorbency!
【degree of difficulty★★★☆☆】

Many people may be fond of diatomaceous earth bath mats, which dry quickly and are always dry.
Its greatest feature is its high water absorbency, but after many years of use, its water absorbency may decrease.
In such cases, abrasives come into play.
After years of use, dirt such as sebum and dust adhere to the surface, preventing it from absorbing water, which is the cause of reduced water absorbency.
By removing this dirt through polishing, it is possible to restore water absorption.

～What to prepare～
・Dry abrasive paper #400 or #320
・scissors
・brush

Polish the dry diatomaceous earth bath mat with #320 to #400 dry abrasive paper cut with scissors to an appropriate size.
It can be polished with a coarser grit, but if you apply up to around #400, it will have a better feel.
The secret to success is to finish the final product to #400.

After polishing is complete, remove the dust from the grinding.
If the diatomaceous earth bath mat has a pattern, a brush can be used to efficiently remove powder from the grooves.
After removing the powder, the surface is quickly wiped with a dry rag to complete the process.

Diatomaceous earth bath mats are eco-friendly products that can be dried and reused.

This is a more difficult process that requires subtle force and technique, but if done well, the original shine of the leather can be restored, so it is recommended.
The key point is to polish the surface in a light stroking motion to the minor scratches, as if you are trying to even out sharp scratches so that they are less noticeable.
Finish by applying leather shoe cream.

It is actually not suitable for daily maintenance as it does not repair the scratches, but only evens them out so that they are less noticeable.
However, it is worth a try when there are noticeable scratches.

6. Summary - Abrasive is a versatile product that can be used for cleaning.

In this issue, we introduced some unexpected uses of abrasives.
You have seen that abrasives have many other uses beyond DIY.
However, due to the nature of abrasive products, the method introduced here only removes the surface, and it is inevitable that minute scratches will be left on the object.
We recommend that you try it once on a less noticeable area before polishing.

In addition, gloves and masks should be worn when grinding to prevent injury and inhalation of shavings.
Please bring gloves and masks with you when purchasing abrasives.
