Are alternatives

Have gained me a marketed coffee machines.
The was from a friend who casually such machines also sells and repairs, me thrived.
Did I, as the machine asked for cleaning, the entspr.Tabletten here on Amazon worried.
The result is absolutely okay, must be, however, why the tablets the same as "irritant" (risk phrase) does not open up to me. Clear, coffee oil and fats are persistent.
But I've just used the next time overdue cleaning, two drops of detergent concentrate. The result was in my opinion even better. And that friend even said he recommends otherwise, since the tablets damage the seals in the machine even above average due to the "Focus", in a later age.
I consume my supply of purification tablets, then I take the more environmentally conscious method with two drops of washing up liquid was.
