another method
To keep your leather couches looking nice, mix one cup of salt water (you can make this with one 3/4 cup tap water and 1/4 cup sea salt), two tablespoons of baking soda, and one teaspoon of flour in a large bowl.
Dip wet rag into the mixture and wipe down the couches. Then dry with a dry rag. It will brighten and clean even the dirtiest leather couches
I can only hope that this is said as a joke?
Cleaning with these ingredients may well make the leather look cleaner but it will do so by removing the finish on the leather. Salt and baking soda are abrassives and will attack the finish. The whole mix will simply grind in the dirt and the residues it will leave on the surface will only attract more dirt and oils.
This really is very strange advice from a 'professional' cleaner and does show a great lack of knowledge of the subject.
First of all, No its not a joke.
Infact if you have actually done the courses yourself and actually studied the the ingredients above in detail and the history of there use you will find that they have been used widely. Infact world wide. For many years.
I will agree that they are slightly abrassive. But only slightly.
The first use of baking soda within the household is for cleaning. Baking soda can clean
almost any surface in your household. Just mixing baking soda with some water and you can clean your stove, sink, counter-top, and so on. When you use baking soda to clean everything looks very shiny and sparkling clean. Baking soda is also good to clean baby bottles it takes out that sour milk formula taste and odor. Baking soda can also be used to remove stains from clothes as well. When washing your clothes just add some baking
soda to remove stains. Baking Soda will deodorize your clothes as well.
Baking soda is a sodium bicarbonate, a normal content that maintains the pH equilibriumit will Polish leather – To remove scuff marks from shoes and soften leather jackets, make a paste of baking soda and vinegar. Your leather purses, shoes, jackets and belts will be clean and soft.
There are many uses!
Use warm water (1 cup) with a teason of vinegar. Dampen cloth and wipe clean . Make sure the leather is finished (does not stain with water!) Leather has a pH of 4.5 and most leather cleaners are at 10. This is OK for car leather, but not for handbags. It will alter the chemistry causing pH damage (recognizable by the spongy texture and cracking)
For ink stains: use a white eraser right away.
DO NOT USE ALCOHOL on ink stains. . It dissolves the ink and smears it.
For other spot soiling use the white eraser, it is effective in removing many different types of dirt
For oil stains, use corn starch. Rub in and let the corn starch absorb the oil. A light bulb is helpful to heat the area which decreases the viscosity of the oil, so that it can be absorbed faster. Brush off with a soft tooth brush.
To remove odor from handbags, place a container of baking soda inside the bag. The larger the surface area the better. Heat will help release the odor, so the baking soda can absorb it. You may have to change out the baking soda a couple of times. Then febreeze the interior of the bag, not the leather.
Keep out of DIRECT sunlight
DO NOT use Saddle soap. It will attack the leather finish and affect the pH. It will break down the leather fibers. It's OK for saddles, that leather is a lot harder, thicker and tougher than handbag leather.
Do not use shoe polish. If not top coated it may rub off on your clothes. Designer leathers are more sophisticated and requires a finish that has flexibility.
There are many ways to clean. But it might not be your prefered way! It does not mean it is incorrect!
And as for the training in cleaning Leather I have done training and have certificates. But they do not teach you everything. As for lack of knowledge on the subject I think that is actually very unfair and uncalled for.
And to prove a point I have taken a phot of my sofa,
Also I have been cleaning my own leather sofa for many many years with baking soda/ salt and it has not tarnished the finish! and it still looks like new! Its over 8 years old.
kind regards
