I personally like the 2 part
bleaches. Start by giving your wood a quick rough sand with a 100
grit paper, this gives the wood a uniform texture and gets rid of
any burnished areas. Apply the Part A liberally to the wood and it
is important to keep it wet. The wood will turn a dark brown. Next
apply the Part B, again a liberal coat - don't play with it, just
get it on quickly. Move the bleach around and keep it wet. After a
few minutes you might want to apply a little more Part B. let the
bleach dry. The next day wash the bleached surfaces with water and
15% vinegar solution to neutralize the bleach. Let dry 1-3 days
before finish sanding.
Things to watch out for:
If bleach splashes on something
the spot is there forever, even if you bleach the object it will
always be lighter than the surrounding surface so.....bleach both
sides of a door at the same time, and on vertical surfaces start
from the bottom and work up. Keep unbleached items out of the way
until you are ready to bleach them.
Use separate rags for Part A and
Part B to avoid diluting the solutions. Avoid letting the rags come
in contact with each other.
When sanding wear dust masks and
rubber gloves, any moisture, like sweat or your moist breath will
reactivate the bleach and cause a burn - even though it was
Watch your sanding so you don't
sand thru the color.
Make sure the wood is totally
dry before proceeding to your sanding steps.
The Part B is an oxidizer and
will cause steel to rust. This includes nails, screws or tools that
happen to be close by.
Safety precautions are a must.
Good ventilation, goggles-not glasses, aprons and gloves. Have a
bucket of the vinegar solution near by incase you get splashed; it
takes a while to notice the pain and an even longer time to make it
stop. Have sawdust available to sprinkle on the floor if it gets
slippery. Always wash your hands before going to the bathroom.
Bleaching is smelly, dangerous
stuff. Plan things out, make safety first and be sure you charge for
your efforts and risks.
