Specialist cleaning brushes, used in combination with Puly products, are extremely effective and well worth the outlay.

If your changing a group seal or gasket you'll see the usual caked on muck underneath and all around the area where the seal previuosly sat.

Use group head cleaning brush and some Puly Milk or Caff and you will have that area shining like new in no time at all.

Often over looked as a gimmick, specialist brushes help you save time, money and energy, they last a long time as well.
