I don't think it can be removed with the standard kind of laundrette here in PH. I have the same problem before but gave the clothes away in the end. Millennium Laundry has had their signage down & supposingly changing name caused partners go separate ways. This is my 6th laundry outlets i utilised. The last one, Queens colored my expensive bedsheet with another color
I have a few white outfits which have yellowed. Haven't worn them for long. The yellow's quite noticeable. Anyone knows of a dobi around PH which can do a good job? The outfits are the type where the materials have specific handling instructions.
