Do I need a pressure washer?
Whilst a hot water pressure washer is undoubtedly the quickest and easiest way to wash off the residue, a cold water pressure washer may yield equally satisfactory results. If a pressure washer is not practical or available, then use a bucket of water, a scrubbing brush, Scotchbrite or similar and a sponge (hot soapy water for solvent-based strippers, warm water, not soapy, for alkali-based strippers). This will usually give good results on reasonably smooth substrates, but be aware that a jet of water is much more effective than the bristles of a brush for removing the dissolved paint from rough or porous surfaces.
Our VACWASH pressure-washer/vacuum cleaner attachment makes it possible to use a pressure-washer in areas where the spray and runoff from a normal pressure-washer lance would be unacceptable.
