I've accidentally wiped an acrylic enclosure with 70% alcohol, externally and internally. It got some crazing on the inside and outside, and the acrylic got a hazy look. I knew beforehand that alcohol was aggressive to acrylic, but I would've never guessed that just wiping it with a small amount of alcohol could lead to crazing so fast.

The enclosure( 0.7 m tall - about 2.3 ft) is used to house electronic components that dissipate heat , and is filled with dielectric oil, that heats up to 70 degrees Celsius(158 Fahrenheit). The exterior is cooled by circulating water at 10 degrees Celsius(50 Fahrenheit), that is inside a 1.2 m( 4 ft)tank. The enclosure walls have a thickness of 10 mm( 3/8"), and the pressure difference between the inside and outside of the enclosure is 12 in H20( 0,4 psi).

My question is, do I continue using the enclosure or should I replace it ?

It is just ugly but I don't think it will cause a rupture anytime soon.

Agreed! How big is the actual cylinder? Is it pressure rated or anything? Next time just clean with a magic eraser and water..
