Summer!! Vintage Hebel Haus Built in 1972: The Situation 01

Good morning, everyone! It is July 23rd, and we are truly having some very hot days lately.
While the heat makes even morning filming feel like a chore these days, this time I would like to talk about "dealing with summer odors and stains that become a concern after turning 50."

Aging odors, stains, and cleanliness! Summer laundry tips for those in their 50s

Since we sweat in the summer, we change our white T-shirts multiple times a day, don't we? During this season, men in their 50s and 60s are particularly concerned about "clothing odors and stains."
Also, as we get older, the cleanliness of our clothing becomes important. Even when looking at people of the same generation in town or at the hospital, incorporating white or beige into tops and pants gives a clean, refreshing, and youthful impression.
But! I think many people avoid white shirts because stains and dirt stand out!

The solution!
To conclude, the method of using "Kitchen Haiter" as a last resort limited to white items is chemically sound, and there is a logical reason why it removes stains overwhelmingly well.

However, because there is a risk of damage to clothing, it is safer to use it after understanding "why Kitchen Haiter removes stains so overwhelmingly well" and the mechanism of "Wide Haiter."

Why does Kitchen Haiter remove stains so overwhelmingly well?

The biggest reason is that the "chemical type (strength)" as a bleach is fundamentally different.

Bleach Type Main Products Bleaching Ingredient Features/Ease of Removal Oxygen-based (Powder)OxiClean, etc. Sodium percarbonate Weakly alkaline. Can be used on colored items, but takes time for stubborn stains.
Oxygen-based (Liquid)Wide Haiter, etc. Hydrogen peroxide Acidic. While safe for colored items, the bleaching power itself is the mildest.
Chlorine-based (Liquid) Kitchen Haiter etc. Sodium hypochlorite Strongly alkaline. The power to destroy and decompose pigment molecules themselves is the strongest.

The reason why oxygen-based (Wide Haiter) doesn't work even if you make it concentrated

Wide Haiter (liquid) is made with ingredients (hydrogen peroxide) that intentionally suppress bleaching power so as "not to remove the patterns of colored items." Therefore, no matter how much undiluted solution you apply, it cannot reach the decomposition power of the chlorine-based Kitchen Haiter.

Also, Kitchen Haiter contains not only sodium hypochlorite but also "surfactants" and "strong alkaline ingredients."

• Strong alkali + hot water: Intensely decomposes (saponifies) and dissolves curry oils or pasta fats

• Sodium hypochlorite: Powerfully destroys the remaining turmeric in curry or the strong polyphenol pigments in coffee

Because this double effect works, stains that wouldn't budge with Wide Haiter are removed instantly.

2. Is it a "yes" or "no" to use Kitchen Haiter on white shirt stains?

If limited to "white cotton or 100% polyester clothing," it is a very effective and logical method as a last resort.

However, please be careful of the following 3 risks.

① Fibers get damaged and holes become more likely to form

Because chlorine-based products are too strong, soaking them for a long time or using too high a concentration will dissolve and thin plant fibers like cotton.

② White clothing may "turn yellow"

• UV-cut processing or special coatings: May react with chlorine and turn yellow.

• Nylon or polyurethane (stretch materials): Will deteriorate and turn yellow due to chlorine.

③ Resin care processing (collars and cuffs) turns yellow

The interlining (adhesive resin) inside the collars and cuffs of dress shirts can react with chlorine and turn bright yellow.

3. How to use the 'last resort' method safely and effectively

The method you are already practicing works perfectly, but I have organized the best steps to make your clothes last longer.

1. Apply to the specific spot

   1. Instead of soaking the whole item, use a cotton swab or spoon to apply highly diluted kitchen bleach only to the stained area.

2. Leave on for '5 minutes to a maximum of 15 minutes'

   1. Applying hot water (about 40–50°C) will drastically increase the reaction speed. Since leaving it too long will damage the fabric, rinse it off immediately once the stain disappears.

3. Rinse thoroughly and proceed to normal washing

   1. If chlorine remains, it can cause the fabric to turn yellow after drying, so rinse well before putting it in the washing machine.

Summary: Guidelines for proper use

• Everyday laundry, mild stains, colored/patterned items, odors ➔ Soak in OxiClean (powder) thoroughly dissolved in 50°C hot water

• Last resort for stubborn curry, coffee, or oil stains on white items ➔ Short-term, spot application of kitchen bleach

If you have a favorite white T-shirt you really don't want to throw away, the current approach of 'diluted kitchen bleach + hot water' is scientifically the ultimate secret trick. Just be careful about fabric damage and use it sparingly on specific spots!

Housework as rehabilitation

The swelling in my broken foot has gone down quite a bit after about 3 weeks, but I still shouldn't push it. Even so, I am doing a little bit of daily housework as rehabilitation, such as carrying laundry up the stairs while using the handrails in the house.

Information on laundry supplies we love in our home

I've been using two of these since last year as they help with indoor drying and room air conditioning!

I use this every time for odors and light stains. Soak for 2 hours in 40°C–60°C lukewarm water.

Because it is a low-temperature active detergent, it can be used in any season.

The really hot days are continuing, so please take care of yourselves!
