How to remove white deodorant marks

Short answer: White streaks from deodorant are aluminium salts that have settled into the fabric, and water alone will not wash them out. Vinegar dissolves the residue, but prevention is easier than removal. Give deodorant time to dry before getting dressed, and the problem shows up far less often.

Vinegar dissolves aluminium salts

Dab the mark with white vinegar mixed one to one with water, and let it work for about twenty minutes before washing. The acid in the vinegar breaks down the salts so they rinse out with the rest of the load. See bamboo t-shirts for men.

Let deodorant dry before dressing

Wet deodorant transfers the most onto fabric because it has not yet settled onto the skin. Waiting two minutes after applying makes a big difference to how much ends up on your clothes. See bamboo underwear for men.

Avoid building up layers

Old residue collects new layers every time you apply deodorant again. Wash the underarm area every time you wash the garment, so aluminium salts do not accumulate over several days. See bamboo clothing for men.

Aluminium free deodorant solves it

Without aluminium there are no white streaks to worry about. Many aluminium free deodorants work well against odour, even though they do not reduce sweat the same way. See bamboo socks for men.

Brush the fabric before washing

A dry brush can remove some of the loose white residue before the garment even reaches the washing machine. This makes the vinegar treatment more effective, since it can focus on what is stuck fast.

Change shirts more often in hot weather

The more you sweat, the more deodorant transfers onto the fabric during the day. In hot spells, it can help to change your top an extra time, so the same garment does not collect several layers of streaks.

Wash at the right temperature

Too low a temperature can leave traces of aluminium salts in the fibres, while too much heat can set the mark permanently. Follow the label's washing instructions, and use the vinegar treatment as an extra step before the actual wash.

Try a toothbrush for stubborn marks

If the streaks have dried in firmly, a soft toothbrush can help work the vinegar mixture into the fibres. Rub gently in small circles so you do not wear down the fabric unnecessarily.

Check the result before the dryer

As with other stains, heat sets aluminium salts that have not been fully washed out. Always check the fabric in daylight, and repeat the vinegar treatment if any residue is still visible after washing.
