20/10/4/1Pc Limpador de vidro de pára-brisa de carro compacto efervescente comprimidos detergente

Received 10 small effervescent tablets (1 for 4 liters of water for a total of 40 liters of car windshield washer product) remains to be seen if it is really effective. The color of the water changes to a very beautiful blue but the scent needs to be reviewed because really not terrible otherwise I tested this product as a car windscreen washer and it did the necessary on the windshield, all visible traces have been cleaned ... I recommend this product to everyone without problems thank you joom for this gift ordered with my points

Very difficult to solve, better to dissolve it separately, then put it in the car. I did not notice any good effects. Some time ago I bought from another seller, they dissolved in a minute, and they had a strong color and smell. These are not quality!

does not dissolve in water. it's just a tablet in water. i left it for 30 minutes and it didn't work. I tried again with a different tablet. the same thing happened.

Of the 10 delivered, 3 had already crumbled and were scattered around the packet as fine dust. For the money, the tablets are a bit too expensive for me.
