What to do when shoe polish go bad?

The polish will start to melt, which signals your water is hot enough. Let it cool down, seal the tin and your shoe polish is back to normal.
What’s the difference between Wax and Liquid/Cream Polishes?
A wax polish does its wonders to the outer of your leather shoes by adding layers of wax on it. They do not seep into the leather so they can be buffed to a high shine. They’re old fashioned and classic, making your shoes always look like new.
A liquid/cream polish adds color to your shoes and keeps their original finish. They have small amounts of wax and are rich in pigments leaving more of a matte finish to your shoes.
How do you store your shoe polish properly?
Shoe care products are usually seldom purchased by the average consumer because they last a long time even for the most frequent users. Their sales have even declined over the years as more and more people ditch formal footwear instead of sneakers for everyday use. It is best to use proper storage techniques to get the best result out of your shoe polish every time.
If you have a wax shoe polish, storing them at room temperature and making sure the can is airtight should do the trick, it will avoid shoe polish go bad. If the wax has cracked or crumbled over time, massage the surface of the wax or apply a little heat to melt the wax back together.
Room temperature storage also works well for both liquid and cream-emulsion-based shoe polishes. Since they’re water-based products, solvents can evaporate if your bottle is not properly sealed.
Don’t forget to seal the bottle’s cap so you’ll always get the same gloss and shine in every use.
How do you re-use old shoe polish?
You’ll often see a white-ish layer on top of your shoe polish if you’ve opened them but haven’t used it for a while. This normal result of “sweating” or wax bloom as the shoe polish experiences rapid heating and cooling. This “wax bloom” is fairly common amongst wax-based cosmetic products, art supplies, chocolates, fruits, and more. It’s a sign of shoe polish go bad.
To make your old shoe polish reusable, you must use heat. Fill up a pan or a tray with water then heat it up on a stove. Put your shoe polish in the tray and check until it melts.
Remember not to overheat it to avoid burning the shoe polish. If this does not apply to you, holding a lighter underneath it can be an alternative.
You can also place it near a heat source such as a floor vent or a radiator until the wax softens. After this is done, cool the wax down until it’s ready for use.
