If you’re considering the viral vinegar laundry trick, there’s a useful idea behind it—but the claim that vinegar is the secret to whiter whites and softer towels is overstated.
How vinegar can help
White distilled vinegar can help dissolve detergent and mineral buildup, particularly on towels washed in hard water. That buildup can make towels feel stiff and less absorbent. Clorox™+1
For whitening, however, vinegar isn’t a substitute for a proper laundry whitener or bleach. Its main benefit is removing residue rather than bleaching fabric. Clorox™
The important safety point
There’s conflicting advice about routinely putting vinegar into washing machines. Some manufacturers warn that its acidity can eventually damage rubber seals and hoses, so check your washer manufacturer’s instructions before making it part of every wash. Whirlpool+1
Never mix vinegar with chlorine bleach. The combination can release toxic chlorine gas. Whirlpool
For towels that have become stiff, a safer first step is to use the correct amount of detergent, avoid overloading the machine, wash at the hottest temperature permitted by the care label, and dry them thoroughly. cleaninginstitute.org+1
So, vinegar can be useful for residue and odor problems, but it isn’t a miracle whitener—and regular use in your washing machine isn’t necessarily appropriate.
