Laboratory evaluations of alternative cleaning products
There are no related objects.
Four products were diluted to 5% and heated to 130 F. Stainless steel coupons were coated with Black dye ink.
Although water was not tested, it could have been included and done well. The dye was not truly adhering to the surface until it had dried there. The dye was removed within the first minutes (1-2) of the immersion, in most cases.
Three of the four removed over 80% of the ink.
