Hello
Welcome to fixya.
I'm Huuum and happy to assist you,

You said,you have a Eurotech front loader. Lately you have observed that your cotton materials come out with oily spots after wash. What can one use to address this problem.

In most front loaders when this happens it is usually either of two things.
1.Front loaders must have HE detergent for their use and if you do not use HE detergent you must cut your detergent and bleach in half.
Because to much detergent destroys your seal and eventually your bearings! And any other rubber seals like the rubber door seal in the front opening.
These degrade and get into the wash and depending on the color of the rubber (Black or gray) are found to stain your clothing or leave a residue in those colors.!
Those washers with Grey rubber like Maytag's have gray stains and or residues!
I have people asking me about this problem every day!

Call the manufacturer and ask if they have any cleaner that you can run once with out clothes to put an end to this!
And then use HE detergent and or half the dose of bleach form now on!

I hope this brings some lihgt to your problem. Please let me know what the Eurotech proplr tell you to use to clean it out of your washer!

Please remember to leave a rating before you go!
Thank you
