This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan.
Quick take
The JASON MARKK Essential Kit cleaned a pair of off-white knit sneakers without a rinse. Wet the brush, add the solution, brush it into a foam, then wipe it off. About five minutes per shoe made a clearly visible difference, and the fabric parts were fine too.

What I tested
- JASON MARKK Essential Kit (cleaning solution and standard brush)
- A pair of lightly soiled, off-white knit sneakers
- A bowl of water and a cloth for wiping
How I used it
- Dip the brush in water so it is just damp
- Put a little solution on the brush, then add a touch more water
- Brush the whole shoe; it foams up quickly
- Wipe the foam off with a cloth. No rinsing needed

What I found
- Fast results. About five minutes of brushing per shoe was enough to see a big difference. Doing both shoes carefully took around 15 minutes.
- No drying hassle. Because you wipe instead of rinse, you avoid the long drying time of machine or hand washing.
- Gentle enough for knit fabric. The bristles are firm, but brushing lightly through the foam did not damage the fabric.
- Mild scent. It smells pleasant rather than like detergent. I wore gloves, but the solution did not feel harsh.
- Not perfectly white. On light-colored shoes it removed dusty dirt and darker marks, but did not make them brand-new white.
Who it’s for
It suits people who wear sneakers every day and want to keep light-colored pairs looking clean with quick, regular touch-ups instead of full washes.
Watch the review
The video is in Japanese, but the before-and-after is easy to follow. Useful moments: around 1:00 for the steps, 3:15 for the side-by-side comparison, and 7:00 for the tip about splashing.
Limitations
I cleaned one pair of knit sneakers and did not clean the soles. The firm brush flicks foam around, so work somewhere you don’t mind getting a little messy.
