I work as a mechanic and wash my work clothes at home, because I can not stand the dry cleaning that offers my employer. To grease, dirt, dust, grease etc ever get shut out, stay me 2 ways ... 1. The matters to wash above 60 ° C, with the result shrinkage things greatly. Or 2. I wash them at 40 ° C and give depending on the degree to Sil. Advantage ... things do not run a ... at least not so quickly. Clear manages Sil not really get all the deep-seated dirt out, but it creates the most of the spots. So I can say ... at least Monday to start work I run with clean work clothes rum -D. I use Sil even with my normal clothes and I am very satisfied! Until now I have that all stains out though I get on my clothes 95% 40 ° C and wash in the short wash cycle of 45 minutes. So I can only recommend Sil.
