What Is a Remedy for Fiberglass Rash?

Remedies for fiberglass rash include blowing compressed air on the affected area, application of a topical steroid cream, taking antihistamine medications that contain diphenhydramine and application of nail polish remover to the affected area, according to Made Man. These are home remedies, and the supplies needed for these treatments are all available over the counter. Depending on the case, one or more of these remedies may be needed.

Made Man explains that fiberglass rash usually results from handling insulation. Since fiberglass is made from bits of microscopic glass, those who handle it are at risk of having the microscopic shards of glass become embedded in their skin, causing fiberglass rash.

Blowing compressed air on the rash helps because it loosens the fiberglass that has embedded in the skin. Topical steroid creams and antihistamine medications containing diphenhydramine can be purchased at most drug stores, and they provide for fast relief from fiberglass rash itch. The proper antihistamine medication dosage is 25 to 50 milligrams three to four times daily. Application of nail polish remover to the rash is helpful because the acetone in the nail polish remover melts the glass. To use this method, Made Man advises dampening a cloth with the nail polish remover and wiping the affected area. Fiberglass rash can be prevented by wearing protective gloves, clothing and safety glasses while handling insulation.
