I have a tile patio with 1/4" grout lines between the 16" tiles.

In a few places, the grout has cracked and disintegrated, probably due to
thermal expansion.

Prior to replacing the grout, what is the best way of removing the remnants
of the grout from the spaces between the tiles.


A small area use a grout saw. HD will have them.

Somebody suggested the HF Multifunction Power Tool ($ 19.99). Would this
work? Any betters suggestions?

Yes and maybe.

Remove grout in a fraction of the time – including epoxy and urethane

¦Fits all reciprocating saws; insert as you would a standard blade

¦Made from carbon steel with a carbide grit edge for maximum
performance and control

¦1/16? is intended for joints 1/16? to 3/16? widths

¦3/16? is intended for joints 3/16? and wider

¦Do not use with saws operating with orbital action
