Calgon 4-in-1 Washing Machine Cleaner and Water Softener Tablets, Removes Limescale & Odours, Deep Clean, Units: 15 Tablets, Pack of 1 (Packaging May Vary)

cleans machine really well. all bad smell removed does a great job for a good price

Great fresh and good quality functions well.

This little square does what it says on the box cleans round rubber on door and drum and leaves it smelling fresh great job .

Excellent product, must save lots of money on washing machine repairs.

These are excellent! My washing machine smelled awful, tried other cleaners and it was fresh for about a day at the most. They seemed to just freshen rather than actually clean. These don’t really leave a scent behind, but the bad smell has gone completely!! Washing is coming out cleaner and fresher too.I don’t use one in every wash. I used two in the first load to clean it, then pop one in every now and then as I do a LOT of washing.Will definitely keep buying these

Certainly brightened the drum of the machine but that was as far as it went. Odour was still present after using 2 tabs in an empty machine on hot cycle.Disappointed!

Seems to do exactly what it claims. I'll buy again

These are okay but don’t seem quite as good as some of the one off service type cleaners. Handy to throw in with each wash though. I have a Labrador with quite a lot of hair so after washing his blankets or towels the machine can get a hair build up. I’m hoping these will prevent unpleasant smells or blockages. So far they are okay.
