Mr Hard Water Blast Gun - 0 Degree

The Mr Hard Water Blast Gun - 0 Degree is a complete cleaning system for any surface that can be cleaned with a zero degree nozzle.  Able to accommodate many types of media, this kit is simple yet powerful.  A sand stake can be inserted into the desired media.  As the water is forced through the blast aperture via a pressure washer, sufficient suction is accomplished to draw through the media through the mixing valve.  

It's easy to accommodate different pressure washers.  Regardless of the pressure washer's output, the user can adjust the vacuum (suction power) created within the mixing valve by inserting one of four different sized nozzle jets inside valve body.  This allows the user to optimize the performance of the suction power to the pressure washer's output.

Professionals can use their Pool Tile Cleaning License to buy the media from local suppliers. Home owners generally need a contractor’s license to buy from local suppliers.  This can restrict their access to the media.  Mr. Hard Water does sell to home owners.  However, shipping costs apply to all media sales.


Media types dissolve at different rates when mixed with water.  Media types also differ in pH.  This affects of plants health.  pH-neutral media is recommended around vegetation.  Media types also vary according to hardness and break down during impact.  For example, sand is very hard and does not disintegrate upon impact whereas other media will.  As a result, cleaning effectiveness, pitting, stripping, and other featureas associated with blasting are determined by the type of media used.

For quick clean up, capture undissolved media using a tarp and then dispose in a safe place.
