I have some mothers wax and sealer that over time got very thin. Even after shaking it for a good while it still seems very watery and milky colored not creamy like I remember it. Should I just toss it??
Yes it can actually get moldy . Don't store applicator inside your paste wax can ,this can contaminate it. Synthetic waxes will last the longest but in my opinion don't do as good a job as the naturals. when in doubt throw it out wax is cheap.
