We Claim:
1. A downhole cleaning tool (1) for removing residues or precipitation solids (2) on an
inner face (3) of a casing (4) or liner, comprising:
- a tool body (5) having a bore (6) and a wall (7),
- at least one inlet (8) in the wall of the tool body, said inlet being fluidly connected with the bore,
- a solid removing element (16) connected with the tool body for releasing solids of the inner face of the casing or liner, and
- a fluid cleaner section (17) comprising:

- a chamber (18),
- a filter (19) within the chamber for separation of the solids from the fluid, and
- a pump (20) fluidly connected with the bore for sucking fluid with released solids in through the inlet into the chamber,
wherein the solid removing element comprises at least one projecting part (10) projecting from the tool body and a spring (11) arranged between the tool body and the projecting part, and wherein the at least one inlet is arranged adjacent the projecting parts for suction of released solids.
2. A downhole cleaning tool according to claim 1, wherein the projecting part projects radially from the tool body.
3. A downhole cleaning tool according to claim 1 or 2, wherein the projecting part is radially movable in relation to the tool body.
4. A downhole cleaning tool according to any of the preceding claims, wherein the projecting part comprises bits (14) arranged facing the casing.
5. A downhole cleaning tool according to claim 3, wherein the radially movable projection part is connected with the tool body by means of a restricting element (27), so

that the spring forces the projection part radially outwards to have a distance (28) to an outer face (34) of the tool body.
6. A downhole cleaning tool according to any of the preceding claims, wherein the projecting part has an increasing thickness along an axial extension of the tool body.
7. A downhole cleaning tool according to any of the preceding claims, wherein the tool comprises a plurality of projecting parts arranged spaced apart along a circumference of the tool body.
8. A downhole cleaning tool according to any of the preceding claims, wherein the spring is releasably arranged in bores (33) in the tool body in the groove or the projecting part to maintain the spring in position.
9. A downhole cleaning tool according to any of the preceding claims, wherein the tool body is connected with the fluid cleaner section, so that the bore (6) is connected with the chamber.
10. A downhole cleaning tool according to any of the preceding claims, wherein the solid removing element is arranged furthest away from the wireline.
11. A downhole cleaning tool according to any of the preceding claims, further comprising a bit head (24) arranged at a leading end of the tool body.
12. A downhole cleaning tool according to any of the preceding claims, wherein the tool body is rotatable.
13. A downhole cleaning tool according to any of the preceding claims, wherein the pump is fluidly connected with an outlet (15) of the fluid cleaner section.

14. A downhole cleaning tool according to any of the preceding claims, further comprising a driving unit (25), such as a downhole tractor, for propelling the tool forward in the casing.
15. A cleaning method for removing residues or precipitation solids (2) on an inner face (3) of a casing (4) or liner, comprising the steps of:

- introducing a downhole cleaning tool (1) according to any of the claims 1-14 into the casing or liner,
- drilling into the solids for releasing the solids,
- sucking fluid containing the solids in through the inlet (8) in the wall of tool body,
- filtrating the solids from the fluid in the filter, and
- pumping the filtrated fluid back into the casing through an outlet (15) in the tool in an end of the tool closest to a wireline (23).
